“Your Mac is infected with 3 viruses” popup alert removal
Learn how to get rid of annoying “Your Mac is infected with 3 viruses” browser alerts and get best practice tips on dealing with tech support scams like that.
Cybercrime and social engineering go hand in hand these days. Targeting computer software alone tends to be much more difficult than exploiting human weaknesses, so to speak. Rather than focus on a single attack vector, though, some threat actors prefer combining the two. This is how tech support scams work. The fraudulent campaign to be analyzed herein revolves around bogus browser alerts saying, “Your Mac is infected with 3 viruses” or “Your system is infected with 3 viruses”. The message sure sounds scary, doesn’t it? Having stumbled upon it, some Mac users will end up following the malicious prompts provided on the page, and that’s a slippery slope.
Let’s delve into the technical nature of this online fraud. Obviously, Mac users do not go to the spoof web page in question because they want to. These forcible hits are facilitated by perpetrating scripts on hacked sites, or by malicious code previously deposited on the Mac. Some of the domains reportedly involved in this shady activity include apple.com-protect-systems-live, apple.com-supportcenter.pro, apple.com-traffic-cleaner.systems, and som008.site. The redirect begins with a popup warning that provides the following information, “Immediate action required. We have detected a Trojan virus (e.tre456_worm_osx) on your Mac. Press OK to begin the repair process.” The wording may vary, but the idea is to catch the user’s eye and persuade them to proceed. No matter what option is selected on the popup, the incursion moves on and the victim ends up on the main page that goes,
“Your system is infected with 3 viruses!
Your Mac is infected with 3 viruses. Our security check found traces of 2 malware and 1 phishing/spyware. System damage: 28.1% - Immediate removal required!
The immediate removal of the viruses is required to prevent further system damage, loss of Apps, Photos or other files. Traces of 1 phishing /spyware were found on your Mac. Personal and banking information are at risk.
To avoid more damage click on ‘Scan Now’ immediately. Our deep scan will provide help immediately.”
The whole message is a complete fake. However, it is designed quite competently, includes the official logo of AppleCare Protection Plan, and generally looks trustworthy. The ‘Scan Now’ button in the bottom part of the page will download and install MacKeeper, a malware cleanup tool with controversial reputation. It gained notoriety for malvertising activity and false positives used to persuade Mac users to purchase its license. One of the most disconcerting things about the alerts in question is that the browser redirects may be triggered by a hijacker application that changes Internet surfing defaults on a compromised machine.
So, the main takeaway is to refrain from following the recommendations provided by “Your Mac is infected with 3 viruses” scam alerts. Another one is to check the system for browser redirect malware and remove it if detected.
