A New Security Threat Lurks in the Shadows of Your Computer: ClickFix.
ClickFix, a relatively new technique, has emerged as one of the most significant security threats your family may not be aware of. This sophisticated method can bypass many endpoint protections, making it difficult for even the most advanced antivirus software to detect and prevent attacks.
The attack starts with an email or WhatsApp message from a hotel that claims you have a pending registration. The message references your correct registration information, making it seem legitimate. In some cases, the attackers use a search query on Google to serve up a malicious URL at the top of the results page. Once you click on this link, you'll be prompted to copy a string of text into a terminal window and paste it back in.
This may seem like an innocuous request, but it's actually a clever ruse designed to trick you into installing malware onto your computer. The moment you enter the string, the PC or Mac will visit a scammer-controlled server and download the malicious software, which will then install itself without any indication that something is amiss.
Security experts warn that ClickFix campaigns have been running rampant, with attackers using malvertising and social engineering tactics to spread this malware. The technique allows eCrime actors to bypass Gatekeeper checks on macOS, making it nearly impossible to prevent infections.
The primary piece of malware used in these campaigns is a credential-stealer known as Shamos. Other payloads include malicious cryptocurrency wallets, software that makes the Mac part of a botnet, and changes to the operating system's configuration to allow the malware to run automatically every time the machine restarts.
ClickFix scams are particularly effective because they prey on people's trust in online institutions and their reluctance to question instructions from seemingly legitimate sources. With many families gathering for holiday gatherings this season, it's essential that you educate your loved ones about the dangers of ClickFix scams and encourage them to be cautious when clicking on links or responding to suspicious emails.
While Microsoft Defender and other endpoint protection programs offer some defenses against these attacks, they can sometimes be bypassed. Therefore, awareness is the best countermeasure against ClickFix scams.
