“Your Computer has Detected a Potential Problem” Virus – Remove It

This blog post has been created with the main purpose to explain to you what is the WindShift Mac Virus (Your computer has detected a potential problem) and how you can remove it completely from your Mac.

A new Trojan horse for MacOS machines was recently identified to be spread with a very low detection rate. The virus, called WindShift has been labeled more of a Spyware type of virus which aims to revoke certificates and thus be detected by next to none VirusTotal antivirus engines. The Trojan’s primary goal is to infect victims via phishing and then tap onto their Mac’s with the idea to spy on the victim. If you have seen the WindShift also known as WindTail detection on your Mac, we do recommend that you read this article thoroughly.

WindShift – Distribution Methods

WindShift is malware for MacOS machines and it is also known as OSX.WindTail or OSX.WindShift as a detection by most antivirus programs. But you may also encounter this virus by an anonymous detection, such as Trojan.OSX.Agent.c and others. The virus is known to spread via a very unconventional method that is typical for most viruses and that is via phishing pages.

Such pages may often pretend to be the original pages of big websites you may be familiar with, like PayPal, eBay, Amazon, Gmail and other large sites. Below, you can see a fake RayBan website, versus a Phishing one, spreading the RayBan Facebook virus:

But Phishing is not a typical way to spread malware and this could be the primary reason why the people behind this virus used just that. These phishing pages may ask you to click on a button or download a file and this is one way via which one could unknowingly let the WindShift Trojan on their Mac.

WindShift Mac Trojan – Activity

The main infection file according to malware researchers has been reported at VirusTotal to have the following specifics:

→ Name: Meeting_Agenda.zip
IOC: ad282e5ba2bc06a128eb20da753350278a2e47ab545fdab808e94a2ff7b4061e
Size:246.37 KB

Also classified by reports as an APT (Advanced Persistent Threat), the malware may silently enter your Mac without you even realising it. Then, the WindShift Trojan may start to revoke certificates, like the following:

→ CSSMERR_TP_CERT_REVOKED

Shortly after that, the WindShift Malware may begin to cause problems by likely taking down other certificates and as a result of that the “Your computer has detected a potential problem” error message appears on the user’s Mac, looking like the image underneath shows:




The bad news here is that Apple validates Macs’ firmware frequently and this is not likely to happen. This is why, seeing this message along with the CSMERR certificate revoked is the most clear symptom of having the WindShift (“Your computer has detected a potential problem”) Trojan on your Mac.

If the Trojan has already compromised a Mac, researchers report that it could be used to perform the following activities:

  • Record what you do on your Mac.
  • Communicate with the control server of the hackers.
  • Take pictures of your Mac’s desktop.
  • Steal files from your Mac.

But what gets even more interesting is that the Trojan was actually reported in relation to the “Your computer has detected a potential problem” Trojan is that four months ago a hacking group was detected to perform digital espionage with this virus and their malware was undetected. And what is bad here is that even though the servers of WindShift were disabled, the malware is still active and could still be spread. And what is even worse is that it could be used by other hackers to spy on Mac users or could be modified to become something worse than it already is. So, experts advise to be careful, especially if you see the “Your computer has detected a potential problem” message. If this is the case, we recommend checking your Mac for malware and removing it, preferably by following the instructions in the “Remove” section below.

If you know how to detect and eliminate the malicious files by knowing their location and name, we recommend that you follow the first two steps below. However, if you do not seem to find the files or feel unsure that you have removed the “Your computer has detected a potential problem” WindShift Trojan, we would strongly recommend that you follow the other two steps underneath the first two.
