Watch Out for Ransomware Pretending to Be a Windows Update!

Imagine you're diligently working on your computer in Singapore, and suddenly, a Windows update prompt pops up. This time, instead of ignoring it, you decide to act, aiming to keep your device secure. 

But in a cruel twist, the "update" you installed is actually ransomware, a malicious software that locks your data and demands a ransom. Welcome to the unsettling reality of the "Big Head" ransomware, a new cyber threat masquerading as a routine Windows update.

Understanding Big Head Ransomware

Ransomware attacks are notorious for encrypting files and holding them hostage. Big Head ransomware, however, takes deception a notch higher. 

It disguises itself as a Windows update. Imagine receiving a seemingly legitimate update notification, complete with a fake Microsoft digital signature. 

This is exactly what Big Head does, tricking you into downloading and executing the ransomware, which then proceeds to encrypt your files and demand a ransom.

By 2031, it's estimated that a ransomware attack will occur every 2 seconds worldwide.

Safeguarding Yourself from Big-Head Ransomware & Similar Threats in Singapore

Cyber threats are becoming more sophisticated. In the tech-savvy landscape of Singapore, staying ahead of cyber threats is crucial. Here's how you can protect yourself:

Update Wisely

Always ensure your software and systems are up-to-date, yet Big Head ransomware hides behind the appearance of Windows updates. One way to be sure you’re installing a real update is to automate. Automate your Windows updates through your device or an IT provider (like us).

Verify Updates

Double-check the authenticity of any update. Genuine updates will come from Microsoft's official channels or your trusted IT provider. Be cautious of unsolicited update notifications. Especially those received via email or from unfamiliar sources.

Regular Backups

Frequently back up your data to an external device or a secure cloud service. This way, even if you fall victim to ransomware, you can restore your data without paying the ransom.

Install Security Software

Use reliable antivirus and anti-malware programs to detect and block potential threats. This helps prevent them from infiltrating your system.

Stay Informed

Keep yourself and those around you educated about the latest cyber threats. Understand the risks of clicking on unknown links or downloading dubious attachments. Consider signing up for Cyber Security Awareness training for yourself and your team.

Email Safety

Implement robust email security practices. Be sceptical of attachments and links from unknown sources, as ransomware often spreads via phishing emails.

Firewall and Network Security

Activate your firewall and use network security solutions to guard against unauthorised access.

Disable Auto-Run

Prevent ransomware spread through infected USB drives by disabling auto-run features for external devices.

Monitor Your System

Keep an eye out for any unusual PC behaviour, such as slowdowns, missing files, or unexpected processor activity. 

Suspicious PC activity can be:

  • Unexpected system slowdowns

  • File changes

  • Missing files or folders

  • Your PC’s processor “whirring” when you’re not doing anything

Have a Response Plan

In case of an attack, know how to disconnect from the network and report the incident to a cybersecurity expert. Try to avoid paying the ransom if possible.

Need a Cybersecurity Check-Up?

Don't wait for an attack to reveal the vulnerabilities in your system. Regular cybersecurity audits are crucial for identifying potential weaknesses. If you're concerned about your digital safety, consider reaching out for a professional cybersecurity audit. Stay informed, stay prepared, and keep your data safe.
