The AI Revolution in Cybercrime

AI has fundamentally reshaped the economics of cybercrime. What once required skilled hackers and weeks of manual effort can now be executed in hours—or even minutes—by automated systems. Here’s how AI is changing the game:

1. AI-Powered Phishing and Social Engineering

Phishing emails used to be easy to spot—poor grammar, generic greetings, and suspicious links. Not anymore. AI now crafts hyper-personalised phishing campaigns that mimic corporate communication styles and even replicate entire email threads. Attackers scrape social media and company data to create messages that feel authentic, increasing click-through rates dramatically.
Deepfake technology adds another layer of deception, enabling voice and video impersonations of executives during live calls to authorise fraudulent transactions. In one real-world case, a finance worker was tricked into transferring $25 million after attending a video conference populated entirely by AI-generated deepfakes of senior executives. 

2. Adaptive, Self-Evolving Malware

Traditional malware relies on static code, making it easier to detect. AI-powered malware, however, learns and adapts in real time. It analyses security measures, rewrites its own code, and changes behaviour to evade detection. Google reported malware strains like PROMPTFLUX and PROMPTSTEAL that use large language models to autonomously generate new malicious scripts every time they run. This means signature-based antivirus tools are becoming obsolete. Attackers can now deploy polymorphic malware and fileless attacks that slip past traditional defences as if they weren’t even there.

3. Deepfake-Enabled Cyberattacks

Deepfakes have moved beyond social media pranks—they’re now a serious cybersecurity threat. Artificial Intelligence (AI) generated audio and video can impersonate CEOs, government officials, or trusted partners with alarming accuracy. In 2025, 85% of organisations reported at least one deepfake-enabled incident, with average losses exceeding $280,000 per attack. These attacks bypass voice authentication systems and exploit trust at scale, making them one of the fastest-growing cybercrime tactics.

4. Autonomous AI Agents

The rise of agentic AI—autonomous systems capable of planning and executing complex tasks—has lowered the barrier to entry for cybercrime. Anthropic’s recent report revealed that attackers used AI agents to automate up to 90% of a cyber espionage campaign, performing reconnaissance, exploitation, and data exfiltration with minimal human oversight.
This shift means even low-skilled criminals can launch sophisticated attacks, dramatically increasing the volume and impact of cybercrime worldwide. 

Why This Matters for Businesses and Individuals

The consequences of AI-driven cybercrime are severe:

• Financial Losses: Global cybercrime costs are projected to hit $24 trillion by 2027.
• Data Breaches: AI accelerates zero-day exploitation, making patching cycles dangerously slow.
• Reputational Damage: Deepfake scams and synthetic identity fraud erode trust in digital communications.

Artificial Intelligence (AI) has supercharged cybercrime, turning traditional threats into highly adaptive, scalable attacks. But the same technology can empower defenders—if organisations act now. Building resilience means combining AI-driven security tools, human expertise, and robust governance frameworks to stay ahead in this arms race.

Why People Prefer Password Managers and Virtual Cards for Online Shopping

Shopping online is quick, easy, and often cheaper than going to physical stores. However, it is fraught with security risks. Many people now use password managers and virtual cards for safer transactions.  A password manager creates and keeps complicated, distinct passwords for all accounts. This minimises the chance of unauthorised access and theft. The Cybersecurity and Infrastructure Security Agency (CISA) recommends using password managers to reduce password reuse and protect sensitive data from hackers. Virtual cards also add an extra layer of protection when shopping online. Although the card numbers are linked to your real credit or debit card account, the merchant never sees your card details. This helps prevent identity theft and financial fraud.

Tips for Using Password Managers and Virtual Cards for Zero-Risk Holiday Shopping

Before you start adding items to your cart, the safety of your money comes first. Here are smart ways to use these tools to improve online security during the holidays.

Choose a Reputable Password Manager

Select a trusted provider with strong encryption and a solid reputation. Popular options include 1Password, Dashlane, LastPass, and Bitwarden. Fake versions are everywhere, so make sure you only download from the official website or app store.

Create a Strong Master Password

Your master password protects all your other passwords and should be the most secure. “Secure” means making it unusual and not something that can be guessed. You can achieve this by combining letters, numbers, and special characters. 

Turn On Two-Factor Authentication (2FA)

2FA adds another protection step by requiring two verification steps. Besides your password, you can choose to receive a verification code on your phone. Even if hackers steal your password, they can’t access your account without your verification code.

Generate Virtual Cards for Each Store

Set up a separate virtual card for each online retailer, many banks and payment apps offer this feature. That way, if one store is compromised, only that temporary card is affected, your main account stays safe.

Track Expiration Dates and Spending Limits

Virtual cards often expire after a set time or after one purchase. This is good for security, but make sure your card is valid before placing an order. Set spending limits as well, as this helps with holiday budgeting and prevents unauthorised charges.

Shop Only on Secure Websites

Be sure to purchase only from websites you are familiar with. Don’t shop from any link in an advertisement or email. You may end up on phishing sites that target your information. The URL of a safe site starts with “https://.” Also, pay attention to data encryption. Look for the padlock symbol on your browser address bar. This indicates that the site has employed SSL/TLS encryption, which encrypts data as it is passed between your device and the site.

Common Mistakes to Avoid for Safer Online Shopping

Even with the best security tools, simple mistakes can put your data at risk. Developing strong security awareness is key to safer online habits. Here are some common pitfalls to watch out for when shopping:

Reusing Passwords

One hacked password can put all your accounts at risk. Keep them safe by using a different password for every site, your password manager makes it easy.to generate and store strong, distinct passwords for each one.

Using Public Wi-Fi for Shopping

Hackers can easily monitor public Wi-Fi networks, making them unsafe not just for shopping but for any online activity. To protect your data, avoid using Wi-Fi in coffee shops, hotels, or airports for online shopping. Instead, stick to your mobile data or a secure private network.

Ignoring Security Alerts

Many people overlook alerts about unusual activity but ignoring them can be risky. If your bank, password manager, or virtual card provider alerts you to suspicious activity, act immediately. Follow their instructions to protect your data, for example, changing your password and reviewing recent transactions for any signs of fraud.

Saving Card Details in Your Browser

While browsers allow card information to be saved, it is less secure than virtual cards. If hackers access your browser, your saved cards are compromised.

The holidays should be about celebration, not about worrying over hacked accounts or stolen card details. Using tools like password managers and virtual cards lets you take control of your online shopping security. These tools make password management easier, protect you from phishing scams, and add extra protection against cybercriminals. As you look for the best holiday deals, include security in your shopping checklist. Peace of mind is the best gift you can give yourself. Need help improving your cybersecurity before the holiday rush? We can help you protect your data with smarter, easy-to-use security solutions. Stay safe, stay secure, and shop online with confidence this season. Contact us today to get started.

What is Cyber Hygiene?

Cyber hygiene means the care you give to your online stuff. This includes keeping your devices and information clean and safe. Washing your hands stops germs. Good cyber behaviour stops digital germs like viruses and hackers.

Why is it Important?

Criminals online always try new tricks to get your info or mess up your gadgets. Good cyber hygiene stops them. It keeps your stuff private and your devices working well.

How Can You Improve Your Passwords?

Passwords are like keys to your online home. You want them to be strong. Here are some tips:

Use Long Passwords Longer passwords are harder to guess. Try using a sentence. For example, “I love eating pizza on Fridays!” is a good password.
Mix it Up Use different types of characters. Mix in numbers, symbols, and both big and small letters. “I<3EatingPizza0nFridays!” is even better.
Don’t Reuse Passwords Use a unique password for each account. If someone steals one, the others stay safe.

Why Should You Update Your Software?

Updating your software is like getting a flu shot. It protects you from new threats. Here’s why it’s important:

Fix Security Holes Updates usually fix problems in your software. These are holes that bad guys can use to get in. Updating closes these holes.
Get New Features Updates can also give you new cool stuff. Your apps may work better or do more things.
Set Automatic Updates Turn on automatic updates when you can. Then you don’t have to remember to do it.

How Does Two-Factor Authentication Work?

Two-factor authentication is like putting two locks on your door. It makes it harder for bad guys to break in. Here’s how it works:

What is 2FA? 2FA needs two things to prove it’s you. Usually, one thing is your password. The second thing might be a code sent to your phone or your fingerprint.
Why Use 2FA? If someone steals your password, they still can’t get in. They don’t have the second thing. It’s much safer.
Where to Use 2FA Use 2FA on all your important accounts. These include email, banking, and even social media.

Are You Being Careful on Public Wi-Fi?

Public Wi-Fi can be very dangerous. It’s like yelling in a crowded place. Anyone could listen. Here’s how to stay safe:

Using a VPN A VPN is like a secret tunnel to the internet. It keeps your information private, even on public Wi-Fi.
Avoid Sensitive Tasks Don’t do banking or shopping on public Wi-Fi. Wait until you’re on a safe network.
Turn Off Auto-Connect Don’t let your device connect to any Wi-Fi network by itself. It might connect to a fake, bad network.

How To Identify Phishing Scams?

Phishing is when a bad guy tries to trick you into giving away your information. It’s like a fake fisherman trying to catch you. Here’s how to avoid the hook:

Check the Sender Look closely at who sent the message. Scammers often use names that look real but aren’t.
Don’t Click Suspicious Links If a link looks weird, don’t click it. Move your mouse over it to see where it really goes.
Be Wary of Urgent Messages Scammers often say you need to act fast. Real companies rarely do this.

Are You Backing Up Your Data?

Backing up is like making copies of your important papers. If something bad happens, you don’t lose everything. Here’s why it’s important:

Against Ransomware Ransomware can lock up your files. With backups, you can tell them to go away.
Recover from Accidents Sometimes we delete things by mistake. Backups let you get them back.
Use the 3-2-1 Rule Keep 3 copies of your data, on 2 different types of storage, with 1 copy off-site.

How Often Should You Review Your Privacy Settings?

Your privacy settings are like curtains on your windows. They let you control what others see. Check them often:

Schedule It Check your privacy settings every few months. Write it down so you don’t forget.
Check All Your Accounts Don’t forget about old accounts. If you don’t use them, close them.
Limit What You Share Only share what you need to. The less you share, the safer you are.

Are You Teaching Your Family About Cyber Safety?

Cyber safety is for everyone in your family. It’s like teaching kids to look both ways before crossing the street. Here’s how to spread the knowledge:

Make it Fun Use games or tell stories to teach about cyber safety. It’s easier to remember that way.
Lead by Example Show good cyber habits to your family. They learn by watching you.
Talk About Online Experiences Have open talks about what happens online. That keeps everyone in your house safe.

Want to Level Up Your Cyber Hygiene?

Good cyber hygiene protects you from online bad guys in 2026. Use strong passwords, update your software, and be careful on public Wi-Fi. Watch out for phishing scams. Always back up your data. Check your privacy settings and teach your family about online safety. Want to know more about staying safe online? We can help! Contact us for more tips on cyber hygiene. Let’s make your online life easier and safer together!

The Rise of the Machines: AI and Machine Learning in Security

Artificial intelligence (AI) and machine learning (ML) are no longer futuristic concepts. They are actively shaping the cybersecurity landscape. This year, we’ll likely see a further rise in their application:

Enhanced Threat Detection: AI and ML algorithms excel at analysing massive datasets. This enables them to identify patterns and anomalies that might escape human notice. This translates to a quicker detection of and reaction to potential cyber threats.

Predictive Analytics: AI can predict potential vulnerabilities and suggest proactive measures. It does this by analysing past cyberattacks and security incidents.

Automated Response: AI can go beyond detection and analysis. Professionals can program it to automatically isolate compromised systems. As well as block malicious activity and trigger incident response procedures. This saves valuable time and reduces the potential impact of attacks.

AI and ML offer significant benefits. But it’s important to remember they are tools, not magic solutions. Deploying them effectively requires skilled professionals. Experts who can interpret the data and make informed decisions.

Battling the Ever-Evolving Threat: Ransomware

Ransomware is malicious software that encrypts data and demands a ransom for decryption. It has been a persistent threat for years. Unfortunately, it’s not going anywhere in 2026. Hackers are constantly refining their tactics, targeting individuals and businesses alike. Here’s what to expect:

More Targeted Attacks: Hackers will likely focus on meticulously selecting high-value targets. Such as critical infrastructure or businesses with sensitive data. They do this to maximise their impact and potential payout.

Ransomware-as-a-Service (RaaS): This enables those with limited technical expertise to rent ransomware tools. This makes it easier for a wider range of actors to launch attacks.

Double Extortion: Besides encrypting data, attackers might steal it beforehand. They then may threaten to leak it publicly if the ransom isn’t paid, adding pressure on victims.

Shifting Strategies: Earlier Data Governance and Security Action

Traditionally, companies have deployed data security measures later in the data lifecycle. For example, after data has been stored or analysed. But a new approach towards earlier action is gaining traction in 2026. This means:

Embedding Security Early On: Organisations are no longer waiting until the end. Instead, they will integrate data controls and measures at the start of the data journey. This could involve setting data classification levels. As well as putting in place access restrictions. They will also be defining data retention policies early in the process.

Cloud-Centric Security: More organisations are moving towards cloud storage and processing. As they do this, security solutions will be closely integrated with cloud platforms. This ensures consistent security throughout the entire data lifecycle.

Compliance Focus: Data privacy regulations like GDPR and CCPA are becoming increasingly stringent. As this happens, companies will need to focus on data governance to ensure compliance.

Building a Fortress: Zero Trust Security and Multi-Factor Authentication

We’re in a world where traditional perimeter defenses are constantly breached. This is why the “Zero Trust” approach is gaining prominence. This security model assumes that no user or device is inherently trustworthy. Users and programs need access verification for every interaction. Here’s how it works:

Continuous Verification: Every access request will be rigorously scrutinised. This is regardless of its origin (inside or outside the network). Systems base verification on factors like user identity, device, location, and requested resources.

Least Privilege Access: Companies grant users the lowest access level needed to perform their tasks. This minimises the potential damage if hackers compromise their credentials

Multi-Factor Authentication (MFA): MFA adds an important extra layer of security. It requires users to provide extra factors beyond their password.

When Things Get Personal: Biometric Data Protection

Biometrics include facial recognition, fingerprints, and voice patterns. They are becoming an increasingly popular form of authentication. But this also raises concerns about the potential for misuse and privacy violations:

Secure Storage Is Key: Companies need to store and secure biometric data. This is ideally in encrypted form to prevent unauthorised access or breaches.

Strict Regulation: Expect governments to install stricter regulations. These will be around the collection, use, and retention of biometric data. Organisations will need to ensure they adhere to evolving standards. They should also focus on transparency and user consent.

How to Prepare for Evolving Data Security Trends

Feeling a bit overwhelmed? Don’t worry, here are some practical steps you and your organisation can take:

• Stay Informed
• Invest in Training
• Review Security Policies
• Embrace Security Technologies
• Test Your Systems

The data security trends of 2026 promise to be both intriguing and challenging. We can help you navigate this evolving terrain with confidence. A data security assessment is a great place to start. Contact us today to schedule yours.

What Are the Most Common Cyber Threats?

They come in so many forms, some old, some new, and very tricky. Here are some of the most common ones you should know about.

Phishing Attacks Phishing attacks will always be in vogue. They make you give away your personal data. It may involve a phony message or fake websites. Always check the sender’s email address. Do not click on suspicious links.

Ransomware Ransomware locks your files and demands money to unlock them. It can spread through email attachments or unsafe downloads. Keep your software updated and back up your files regularly.

Malware Malware is bad software that may cause damage to your computer. It can steal data or spy on you. Use antivirus software and avoid downloading files from unknown sources.

How Can You Protect Yourself Online?

Safety online is important. Here are some simple steps to take to protect yourself from cyber threats.

Use Strong Passwords Use strong and unique passwords for each account. A strong password includes letters, numbers, and symbols. Change your password regularly.

Enable Two-Factor Authentication Two-factor authentication is an added layer of security. When it is in place, one has to take an extra step to log in-for example, getting a code on one’s phone. Whenever possible, turn that on.

Be Careful with Public Wi-Fi Public Wi-Fi is not secure. It is easy for hackers to hack into the data of people who use public networks. Always connect your VPN when using any public Wi-Fi network.

Why is Cybersecurity Important for Everyone?

Cybersecurity doesn’t only apply to big corporations. Everyone should be knowledgeable about cyber threats and their prevention techniques.

Protect Personal Information Your personal information is worth something. Cybercriminals can use it for identity theft or fraud. Be careful about what you share online.

Secure Financial Transactions Online banking and shopping are convenient but risky if not done securely. Use secure websites and monitor your accounts regularly for any suspicious activity.

What Should You Do If You Are a Victim of a Cyber Attack?

Sometimes, despite all precautions, you may still become the victim of a cyber attack. Knowing your next step is paramount.

Report the Incident An immediate report of the cyber attack should be made to the authorities. This could help in investigations and reduce damage.

Change Your Passwords Immediately change all your passwords if you suspect a breach. This prevents further unauthorised access to your accounts.

How Will Cyber Threats Evolve in the Future?

Cyber threats will continually change with emerging technologies. It’s recommended to stay up-to-date on new threats for better protection.

AI-Powered Attacks Cybercriminals will leverage artificial intelligence for more sophisticated attacks. AI supports them in selecting the right victims.

Internet of Things (IoT) Vulnerabilities There are more and more devices connecting via the internet. They start to become the main targets of hackers. Make sure that all devices have updated security measures on them.

Cyber threats are real and growing every day. In this digital age, it is very important to protect yourself online. For more tips on staying safe online, contact us today! We are here to help you keep your digital life secure.

Why Login Security Is Your First Line of Defense

Your most valuable business assets—like client lists, product designs, or brand reputation—can be lost in minutes without strong login security. Nearly half of small and medium businesses have faced cyberattacks, and 1 in 5 never recovered. With data breaches costing an average of $4.4 million, credentials are a prime target. Hackers steal them via phishing, malware, or unrelated breaches, then sell them cheaply online. Many businesses know the risks but struggle with enforcement—73% say getting staff to follow security policies is a major challenge. That’s why solutions must go beyond just “better passwords.”

Advanced Strategies to Lock Down Your Business Logins

Good login security works in layers. The more hoops an attacker has to jump through, the less likely they are to make it to your sensitive data.

1. Strengthen Password and Authentication Policies

• Require unique, complex passwords for every account. Think 15+ characters with a mix of letters, numbers, and symbols.
• Swap out traditional passwords for passphrases, strings of unrelated words that are easier for humans to remember but harder for machines to guess.
• Roll out a password manager so staff can store and auto-generate strong credentials without resorting to sticky notes or spreadsheets.
• Enforce multi-factor authentication (MFA) everywhere possible. Hardware tokens and authenticator apps are far more resilient than SMS codes.
• Check passwords against known breach lists and rotate them periodically.

The important part? Apply the rules across the board. Leaving one “less important” account unprotected is like locking your front door but leaving the garage wide open.

2. Reduce Risk Through Access Control and Least Privilege

• Keep admin privileges limited to the smallest possible group.
• Separate super admin accounts from day-to-day logins and store them securely.
• Give third parties the bare minimum access they need, and revoke it the moment the work ends.

That way, if an account is compromised, the damage is contained rather than catastrophic.

3. Secure Devices, Networks, and Browsers

• Encrypt every company laptop and require strong passwords or biometric logins.
• Use mobile security apps, especially for staff who connect on the go.
• Lock down your Wi-Fi: Encryption on, SSID hidden, router password long and random.
• Keep firewalls active, both on-site and for remote workers.
• Turn on automatic updates for browsers, operating systems, and apps.

Think of it like this: Even if an attacker gets a password, they still have to get past the locked and alarmed “building” your devices create.

4. Protect Email as a Common Attack Gateway

• Enable advanced phishing and malware filtering.
• Set up SPF, DKIM, and DMARC to make your domain harder to spoof.
• Train your team to verify unexpected requests. If “finance” emails to ask for a password reset, confirm it another way.

5. Build a Culture of Security Awareness

• Run short, focused sessions on spotting phishing attempts, handling sensitive data, and using secure passwords.
• Share quick reminders in internal chats or during team meetings.
• Make security a shared responsibility, not just “the IT department’s problem.”

6. Plan for the Inevitable with Incident Response and Monitoring

• Incident Response Plan: Define who does what, how to escalate, and how to communicate during a breach.
• Vulnerability Scanning: Use tools that flag weaknesses before attackers find them.
• Credential Monitoring: Watch for your accounts showing up in public breach dumps.
• Regular Backups: Keep offsite or cloud backups of critical data and test that they actually work.

Login security can either be a liability or a strength. Left unchecked, it’s a soft target that makes the rest of your defenses less effective. Done right, it becomes a barrier that forces attackers to look elsewhere. The steps above, from MFA to access control to a living, breathing incident plan, aren’t one-time fixes. Threats change, people change roles, and new tools arrive. The companies that stay safest are the ones that treat login security as an ongoing process, adjusting it as the environment shifts. You don’t have to do it all overnight. Start with the weakest link you can identify right now, maybe an old, shared admin password or a lack of MFA on your most sensitive systems, and fix it. Then move to the next gap. Over time, those small improvements add up to a solid, layered defense.

What is encryption?

It is the process of converting readable data into an unreadable format using algorithms and keys. Think of it as locking your data in a digital vault—only those with the correct key can access it. Whether you’re sending an email, storing files, or accessing cloud services, encryption ensures that your information remains confidential and secure.

Why it matters?

According to the Australian Federal Government’s Data Breach Report, 63% of breaches happen to businesses with fewer than 100 staff.  That means small and mid-sized enterprises are prime targets. Without encryption, sensitive data like passwords, financial records, and customer details are vulnerable to interception and misuse.

How it works

Encryption is the process of converting readable data (plaintext) into an unreadable format (ciphertext) to protect it from unauthorised access. Only someone with the correct decryption key can convert the ciphertext back into its original form.

There are two main types:

Symmetric Encryption: Uses the same key for both encryption and decryption. It’s fast and efficient, ideal for encrypting large amounts of data. Examples include AES (Advanced Encryption Standard) and DES (Data Encryption Standard)

Asymmetric Encryption: Uses a pair of keys—one public and one private. The public key encrypts the data, and only the private key can decrypt it. This is commonly used in secure email and digital signatures.

What are the challenges?

Encryption is a powerful tool for protecting sensitive data, but it comes with several challenges that organisations must navigate. One major issue is key management, which involves securely storing, rotating, and distributing encryption keys—any misstep can compromise the entire system. 

Performance and latency are also concerns, especially when encryption layers slow down remote access or real-time applications. Additionally, user experience can suffer due to complex authentication steps and compatibility issues with browsers or devices.

Organisations must also ensure compliance with regulations like Australia’s Privacy Act, as poor encryption practices can lead to legal and reputational risks. Choosing the right encryption algorithm is critical, as outdated or unsuitable methods can expose data to attacks. 

Finally, third-party risks remain a concern—if vendors mishandle encrypted data, the organisation is still vulnerable. Addressing these challenges requires a balanced approach that combines robust technology with user-friendly design and strong governance.

Staying safe

At BarberaIT, we recommend layering your defences with these essential tools:

• Email Security Premium: Prevent spoofing and phishing attacks by encrypting email traffic and verifying sender authenticity.
• Business Password Vaults: Store and encrypt company credentials to prevent unauthorised logins.
• Vulnerability Management: Scan your network for weaknesses before hackers do.
• DNS Filtering: Protect remote workers from malicious websites and botnets.
• ID Verification Systems: Ensure secure remote support by verifying both staff and technician identities

By understanding the different methods can help you choose the right one for your needs. If you want more information or need help securing your data, contact us today!

Where Do Deleted Files Go?
Data on the Dark Web

The post Stay Safe with Encryption appeared first on Barbera IT.

What Happens When You Delete a File?

It’s not as easy as it seems to delete a file. When you send a file to the Trash or Recycle Bin, it is not erased from your hard drive right away. It is instead taken to a temporary storage place and stays there until you decide to empty the bin. The file’s data stays on the hard drive even after the bin is empty; it is marked as free space that can be used by other files.

When you delete a file, you remove its reference from the file system, but the actual data stays. That’s why recovery software can often restore deleted files unless the space has been reused. Think of it like removing a label from a VHS tape—the content is still there, just harder to find. To permanently delete sensitive data, you’ll need special tools. Next, we’ll look at file recovery and the importance of backups.

How Can I Get Back Deleted Files?

To recover deleted files, you need software that can scan your hard drive for data that has been marked as available but hasn’t been written over yet. This method might work if the file was recently deleted and the space it took up hasn’t been filled with new data.

How Software for Recovery Works

The way recovery software works is by scanning the hard drive for areas that have data in them but are not currently linked to any file in the file system. After that, it tries to rebuild the file by putting these parts back together. How well this process works will depend on how quickly the recovery is attempted and whether the sections have been written over.

What File Recovery Can’t Do

File recovery works sometimes, but not all the time. It’s much harder or even impossible to recover a removed file if the space it took up has been written over. It’s also possible for the quality of the recovered file to vary, with some files being fully recovered and others only partly.

Why Backups Are Important

Because file recovery isn’t always possible, it’s important to keep regular copies of important data. This ensures that you can still access a file through your backups even if you delete it and can’t recover it. We’ll discuss more about how different devices handle deleted data and the concept of “secure deletion” in the next section. 

What Does Happen on Various Devices?

Deleted files are handled in a few different ways by different systems. Android phones have a folder called “Recently Deleted” where lost files are kept. This is similar to the “Recycle Bin” or “Trash” on any other computer. Photos and movies deleted from an iPhone are kept in the “Recently Deleted” album in the Photos app for 30 days before being deleted for good.

Secure Deletion

Secure deletion does more than just delete a file from the file system; it also writes over the space it took up to make sure the data can’t be retrieved. This is especially important if you want to make sure that all of your private data is gone.

SSDs vs. HDDs

How lost files are dealt with depends on the type of storage device used. Solid-State Drives (SSDs) handle deleted data more efficiently with a method called TRIM. This can make recovery harder than with traditional Hard Disk Drives (HDDs).  To keep your information safe on multiple devices, you need to know about these differences. Next, we’ll discuss how to ensure that deleted files are really gone and what you can do to keep your data safe.

How To Make Sure Files Are Really Deleted

There is more to do than just putting things in the trash or recycle bin to make sure they are really gone. You need to do more to ensure that the data is safely erased. This is especially important if you want to keep private data safe from unauthorised access. You can safely delete files with software that is designed for that purpose. These tools delete files and then overwrite the space they filled several times, making it almost impossible to recover the data. In order to keep private data safe, this step is very important and is called “secure deletion.” Good data management practices can help keep your data safe and secure in addition to secure deletion. Some examples are making regular backups and encrypting your data. 

To sum up, if you want to keep your digital life safe, you need to know where deleted files go and how to recover them. You can keep your information safe from unauthorised access by managing your data and backing it up regularly. If you need help safely deleting sensitive files or have questions about how to handle your data, please contact us.

IoT Security Risks for Small Businesses

The post Where Do Deleted Files Go? appeared first on Barbera IT.

What is IoT?

IoT, or the Internet of Things, is all about physical devices, like sensors, appliances, gadgets, or machines, being connected to the internet. These smart tools can collect and share data, and even act on their own, all without needing someone to constantly manage them. IoT helps boost efficiency, automate tasks, and provide useful data that leads to smarter decisions for both businesses and individuals. But it also comes with challenges, like keeping data secure, protecting privacy, and keeping track of all those connected devices.

Steps To Manage IoT Security Risks for Small Businesses

1. Know What You’ve Got: 

Walk through the office, list all smart devices, note model names and users. With a clear inventory, you’ll have the visibility you need to stay in control during updates or when responding to issues.

2. Change Default Passwords Immediately

Use strong, unique passwords and store them securely. It takes just a minute, and it helps you avoid one of the most common rookie mistakes: weak passwords.

3. Segment Your Network

Let your smart printer talk, but don’t let it talk to everything. Use network segmentation to give each IoT device space while keeping your main systems secure. Create separate Wi-Fi/VLANs for IoT devices; block access to sensitive systems.

4. Keep Firmware and Software Updated

Check monthly for firmware and software updates; automate when possible. Even older gadgets can be secure if they keep receiving patches. Replace devices that are no longer supported

5. Monitor Activity

Once your devices are in place, watch how they talk. Unexpected activity could signal trouble. Track device traffic and set alerts for unusual behavior.

6. Set Up a Response Plan

Incidents happen; devices can fail or malfunction. Know who to contact, how to isolate devices, and what backups are available. A strong response plan lets you respond quickly and keep calm when things go wrong.

7. Limit Device Permissions

Disable unused features and restrict access to only what’s needed. Less access means less risk, yet your tools can still get the job done.

8. Watch for Devices That Creep In

Have a simple approval step for new device and reject or block any gear that can’t be secured. Catching these risks early keeps your network strong.

9. Encrypt Sensitive Data

If your smart devices transmit data, ensure that data is encrypted both during transmission and while stored. Encryption adds a layer of protection without slowing things down.

10. Reevaluate Regularly

Reassess security every 6 months—passwords, updates, and device relevance. With a regular schedule, you keep ahead without overthinking it.

What Are the Most Common Hacking Techniques?

Hacking methods have changed a lot over the years, taking advantage of advances in technology and tricks people are good at. Hackers still use brute force attacks and other old-fashioned methods to get around security measures, but they are becoming more sophisticated. One very common way is social engineering, in which hackers trick people into giving up private information. Another type is credential stuffing, which is when you use stolen login information from past data breaches to get into multiple accounts. There are also attacks that are powered by AI, which lets hackers make convincing fake campaigns or even change security systems. It is very important to understand these hacking techniques because they are the building blocks of more complex and surprising hacking techniques. We’ll talk more about these less common methods and how they can affect your digital safety in the parts that follow.

How Do Hackers Exploit Lesser-Known Vulnerabilities?

Hackers don’t always rely on obvious weaknesses; they often exploit overlooked aspects of digital security. Below are some of the unexpected ways hackers can access your accounts:

Cookie Hijacking

Cookies are small files stored on your device that save login sessions for websites. While convenient for users, they can be a goldmine for hackers. By intercepting or stealing cookies through malicious links or unsecured networks, hackers can impersonate you and gain access to your accounts without needing your password.

SIM Swapping

Your mobile phone number is often used as a second layer of authentication for online accounts. Hackers can perform a SIM swap by convincing your mobile provider to transfer your number to a new SIM card they control. Once they have access to your phone number, they can intercept two-factor authentication (2FA) codes and reset account passwords.

Deepfake Technology

Deepfake technology has advanced rapidly, allowing hackers to create realistic audio or video impersonations. This method is increasingly used in social engineering attacks, where a hacker might pose as a trusted colleague or family member to gain access to sensitive information.

Exploiting Third-Party Apps

Many people link their accounts with third-party applications for convenience. However, these apps often have weaker security protocols. Hackers can exploit vulnerabilities in third-party apps to gain access to linked accounts.

Port-Out Fraud

Similar to SIM swapping, port-out fraud involves transferring your phone number to another provider without your consent. With access to your number, hackers can intercept calls and messages meant for you, including sensitive account recovery codes.

Keylogging Malware

Keyloggers are malicious programs that record every keystroke you make. Once installed on your device, they can capture login credentials and other sensitive information without your knowledge.

AI-Powered Phishing

Traditional phishing emails are easy to spot due to poor grammar or suspicious links. However, AI-powered phishing campaigns use machine learning to craft highly convincing emails tailored specifically for their targets. These emails mimic legitimate communications so well that even tech-savvy individuals can fall victim. In the following section, we’ll discuss how you can protect yourself against these unexpected threats.

How Can You Protect Yourself from These Threats?

Now that we’ve explored some of the unexpected ways hackers can access your accounts, it’s time to focus on prevention strategies. Below are practical steps you can take:

Strengthen Your Authentication Methods

Using strong passwords and enabling multi-factor authentication (MFA) are essential first steps. However, consider going beyond SMS-based MFA by using app-based authenticators or hardware security keys for added protection.

Monitor Your Accounts Regularly

Keep an eye on account activity for any unauthorized logins or changes. Many platforms offer notifications for suspicious activity—make sure these are enabled.

Avoid Public Wi-Fi Networks

Public Wi-Fi networks are breeding grounds for cyberattacks like cookie hijacking. Use a virtual private network (VPN) when accessing sensitive accounts on public networks.

Be Cautious with Third-Party Apps

Before linking any third-party app to your main accounts, verify its credibility and review its permissions. Revoke access from apps you no longer use.

Educate Yourself About Phishing

Learn how to identify phishing attempts by scrutinising email addresses and avoiding clicking on unfamiliar links. When in doubt, contact the sender through a verified channel before responding. In the next section, we’ll discuss additional cybersecurity measures that everyone should implement in today’s digital landscape.

What Additional Cybersecurity Measures Should You Take?

Beyond protecting against specific hacking techniques, adopting a proactive cybersecurity mindset is essential in today’s threat landscape. Here are some broader measures you should consider:

Regular Software Updates

Hackers often exploit outdated software with known vulnerabilities. Ensure all devices and applications are updated regularly with the latest security patches.

Data Backups

Regularly back up important data using the 3-2-1 rule: keep three copies of your data on two different storage media with one copy stored offsite. This ensures you can recover quickly in case of ransomware attacks or data loss.

Use Encrypted Communication Tools

For sensitive communications, use encrypted messaging platforms that protect data from interception by unauthorised parties.

Invest in Cybersecurity Training

Whether for personal use or within an organisation, ongoing education about emerging threats is invaluable. Understanding how hackers operate helps you identify potential risks before they escalate. By implementing these measures alongside specific protections against unexpected hacking methods, you’ll significantly reduce your vulnerability to cyberattacks. In the next section, we’ll wrap up with actionable steps you can take today.
