Ransomware and You

Ransomware and You: What You Need to Know

You may have heard about the recent widespread cyberattack that impacted several major high street brands. It’s one of the largest ransomware incidents in recent years, affecting businesses and individuals around the world. Understandably, many people are left wondering: Am I at risk? As with most types of cybercrime, the best defence is awareness.

What Is Ransomware?

Ransomware is a type of malicious software (malware) that disguises itself as a legitimate file or application. Once installed, it encrypts your files and locks you out of them—demanding a ransom in exchange for access. Victims are often asked to pay in cryptocurrency like Bitcoin, with no guarantee of recovery even if they comply.

Who Is at Risk?

Currently, ransomware is primarily targeting Microsoft Windows computers. Apple devices (iPhones, iPads, and MacBooks) are generally more secure due to strict app store requirements and default system settings that block unauthorized software.

However, if you use a Windows device, especially one that is not regularly updated, you may be at risk.

Important:

Microsoft will officially end support for Windows 10 Home and Pro on October 14, 2025. After that date, no more security updates will be released, which increases your vulnerability significantly.

How to Protect Yourself

You can take several simple steps to reduce your risk and protect your data:

1. 

Keep Your System Updated

Ensure your Windows and Mac OS system has all the latest security patches installed. These updates often include fixes that block ransomware and other threats. Older systems such as Windows 2000, XP, or Vista no longer receive updates and are especially vulnerable.

2. 

Backup Your Data Regularly

Regular backups are your best defence.

• Mac users: Use Time Machine with an external hard drive like the My Passport to easily back up and restore data.
• Windows users: Use built-in backup tools or third-party software to create frequent backups. Store them offline or in the cloud to avoid ransomware encryption.

3. 

Avoid Unfamiliar Software

Ransomware often spreads through deceptive downloads, like fake software updates.

• Only download updates from official websites.
• If a site prompts you to install something you didn’t request or recognize—close it.
• When in doubt, don’t install it.

Already Infected? Here’s What to Do

If your computer is already infected:

• Do not pay the ransom. There’s no guarantee you’ll regain access to your files, and you could lose your money as well.
• There is currently no universal fix for decrypting files without the hacker’s key.
• If you have backups, wipe the system and restore your files.
• Tools like Malwarebytes can detect and remove some threats, but may not recover encrypted data.

If You Suspect a Data Breach

If you believe any of your personal information has been compromised:

• Change your passwords immediately—especially if you reuse them across multiple sites.
• Notify your bank and monitor your accounts for suspicious activity.
• Warn your contacts if their information may have been exposed.
• Watch out for login issues or password changes on your online accounts.

Final Tips

• Never reuse passwords across websites.

Use a password manager or generator to create and store strong, unique passwords.

• Always keep your system and antivirus software up to date.
• Backups save lives—digitally speaking.

Staying informed and cautious is the best way to outsmart ransomware. Taking these preventive steps now can save you a lot of trouble later.
