Watch Out for Ransomware Pretending to Be a Windows Update!

Watch Out for Ransomware Pretending to Be a Windows Update!

Picture this: You’re diligently working on your PC, and a Windows update prompt appears. Instead of brushing it off, you decide to take action because safeguarding your device is paramount. However, what unfolds next is a chilling nightmare – you unknowingly install what you believe is a legitimate update, only to find your system infected with ransomware. 

This is the nightmare induced by an emerging cybersecurity menace. 

Cybercriminals are perpetually devising novel methods to infiltrate systems, encrypting invaluable data and leaving victims with agonizing choices. Once ransomware seizes your system, your PC becomes virtually useless, and you’re confronted with a grim ultimatum: pay a ransom or engage an expert to expunge the malware, all while hoping you have a reliable backup. 

Enter “Big Head” ransomware, a recent variant that takes deception to unparalleled heights, posing as fake updates. It masquerades as a Windows update, employing a devious disguise to dupe its victims. In this article, we’ll delve into the intricate workings of Big Head ransomware, dissecting its deceptive strategies, and equipping you with the knowledge to shield yourself from falling victim to such malevolent attacks. Let’s explore the diabolical tactics it employs and discover how you can protect yourself from falling prey to such insidious threats. 

Good Cybersecurity Habits that Help Prevent Ransomware Attacks

Habit #1: Keep Software and Systems Updated 

Balancing the need for security with the risk of falling victim to deceptive updates is a challenging endeavor. One way to navigate this precarious landscape is through automation. Automate your Windows updates either through your device or a trusted IT provider like us. This increases your chances of spotting a rogue update that unexpectedly appears. 

Habit #2: Verify the Authenticity of Updates 

Before installing any software update, take a moment to verify its authenticity. Genuine Windows updates will originate directly from Microsoft’s official website or your trusted IT service provider through Windows Update settings. Exercise caution when encountering unsolicited update notifications, especially those received via email or from unfamiliar sources. 

Habit #3: Backup Your Data 

The cornerstone of ransomware defense is a robust backup strategy. Regularly back up your essential files, utilizing an external storage device or a secure cloud backup service. In the event of a ransomware attack, having backup copies is the same as having a safeguarded vault of your invaluable data. 

Habit #4: Deploy Robust Security Software 

Equip your computer with reputable antivirus and anti-malware software. These formidable ransomware prevention tools can detect and block ransomware threats, fortifying your defenses and thwarting potential infiltrations. 

Habit #5: Educate Yourself and Others 

Stay well-informed about the latest ransomware threats and tactics. Enlighten yourself and extend that knowledge to your colleagues or family members. Discuss the perils of clicking on suspicious links and downloading attachments from unknown sources. 

Habit #6: Implement Email Security Measures 

Ransomware often proliferates through phishing emails. To thwart these malicious attempts, institute comprehensive email security measures. Approach email attachments and links with caution, and be especially wary of communications from unfamiliar senders. 

Habit #7: Enable Firewall and Network Security 

Activate your computer’s firewall and harness network security solutions to prevent unauthorized access to your network and devices, building an impenetrable digital fortress. 

Habit #8: Disable Auto-Run Features 

Configure your computer to disable auto-run functionality for external drives. This straightforward measure can prevent ransomware from spreading via infected USB drives. 

Habit #9: Beware of Pop-Up Alerts 

Exercise prudence when encountering pop-up alerts, especially those prompting you to download or install software. Always verify the legitimacy of such alerts before taking any action. 

Habit #10: Develop an Emergency Response Plan 

In the unfortunate event of a ransomware attack, having both a well-defined ransomware prevention checklist and a response plan is essential. Know how to disconnect from the network, report the incident to your IT department or a cybersecurity expert, and, if possible, refrain from paying the ransom. 


Don’t leave the shadows of unknown threats lurking in your system. A cybersecurity audit can illuminate the hidden vulnerabilities within your network. It’s a proactive step to ensure the impenetrability of your digital fortress. Ready to take the first step toward fortifying your defenses? Contact us today, and let’s schedule a conversation.
