Imagine you’re working away on your PC and see a Windows update prompt. Instead of
ignoring it, you take action. After all, you want to keep your device safe. But when you
install what you think is a legitimate update, you’re infected with ransomware.
That’s the nightmare caused by an emerging cybersecurity threat.
Cybercriminals are constantly devising new ways to infiltrate systems. They encrypt
valuable data, leaving victims with difficult choices. Once ransomware infects your system,
your PC is pretty useless. You either have to pay a ransom or get someone to remove the
malware. As well as install a backup (if you have one!).
One such variant that has emerged recently is the "Big Head" ransomware. It adds a new layer of deception by disguising itself as a Windows update. In this article, we'll explore the ins and outs of Big Head ransomware. Including its deceptive tactics. We well as how you can protect yourself from falling victim to such attacks.
Ransomware attacks have long been infamous for their ability to encrypt files. This renders
them inaccessible to the victim until a ransom is paid to the attacker. In the case of Big
Head ransomware, the attackers have taken their tactics to the next level. The attack
masquerades as a Windows update.
Big Head ransomware presents victims with a convincing and fake Windows update alert.
Attackers design this fake alert to trick users. They think that their computer is undergoing
a legitimate Windows update. The message may appear in a pop-up window or as a
The deception goes even further. The ransomware uses a forged Microsoft digital signature. This makes the fake update appear more authentic. This adds an extra layer of credibility to the malicious message. And makes it even more challenging for users to discern its true nature.
The attack fools the victim into thinking it’s a legitimate Windows update. They then
unknowingly download and execute the ransomware onto their system. From there, the
ransomware proceeds to encrypt the victim's files. Victims see a message demanding a
ransom payment in exchange for the decryption key.
By 2031, it’s expected a ransomware attack will occur every 2 seconds.
