Although there are fewer viral attacks on macOS than on Windows, they are not nonetheless nonexistent. However, they most often result from a lack of vigilance on the part of users who download corrupted files. This is particularly the case of the new EvilQuest ransomware which is deployed through corrupted versions of Little Snitch, a firewall available on macOS, downloadable from the web. A modus operandi brought to light by researchers at MalwareBytes.
Once the firewall is installed, the ransomware can be deployed on the machine and block access to the files and other documents saved on it, as well as to the keychain. Keylogger software can also be installed on the computer to record anything the victim types on the keyboard. The only solution for victims to regain access to their machine is to pay the ransom requested.
A single gesture to secure your data
In the case of EvilQuest, the amount demanded by hackers is not very high. It is only $ 50, but cybercrime specialists advise against giving in to the pressures of ransomware. You have no guarantee of actually recovering access to your files and hackers can sometimes even increase the amount if they see that you are ready to pay.
The best thing to do is to regularly back up your files to an external hard drive. If your machine is encrypted using ransomware, you can refuse to pay the ransom without worrying about losing your files. Furthermore, it is obviously advisable to download files from reliable and secure sources. Choose the official websites or the Apple application and software store.
