It is essential that you install up-to-date security software and use your mind when browsing the web to ensure that FessLeak cannot corrupt your Windows operating system. The clandestine threat is also known as Cryptolocker, and if you let it in your PC, you will have all of your personal files encrypted. Unfortunately, many users do not find a way to decrypt personal files, and this is why FessLeak Ransomware is considered to be one of the most obnoxious and harmful threats out there. Even though the infection cannot delete your files, there are no guarantees that you will be able to restore them. Regardless of the outcome, it is most important that you remove the threats associated with FessLeak and take care of your virtual security.
Cyber criminals who have created FessLeak are very smart when it comes to the distribution of this threat. According to our researchers, the infection can use zero-day vulnerabilities in Adobe Flash Player to drop temp files and send commands to icacls.exe to set permissions on files and folders. It is likely that this could be used to bypass existing malware detection and removal software as well. Nonetheless, it is most impressive that FessLeak Ransomware has managed to utilize the file-less ransomware distribution method. It has been discovered that schemers can use the ad-bidding network to get the chance to display unreliable ads on generally secure websites. FessLeak registers a burner domain (registered using fessleak@qip.ru), then links it to a malicious landing page, to which the corrupted ads are redirected. These domains are abandoned within 8 hours, after which the attack is repeated using different burner domains.
As mentioned before, fessleak@qip.ru is the email address that can be used to register for the unreliable domains, and this is why malware researchers identify CryptoLocker as FessLeak Ransomware. So far, the infection has been noted to place corrupted ads on huffingtonpost.com, thesaurus.com, howtogeek.com, and other popular websites. In some cases, FessLeak Ransomware can also be executed after a user clicks a link routing to an article or clicks on a video within the article. Once executed, FessLeak removes itself, which means that no files are left to delete. Despite this, the infection manages to encrypt personal files and present a ransom notification suggesting that a specific sum has to be paid for file decryption. As mentioned before, there are no guarantees that your personal files will be restored after you pay the ransom.
Even though FessLeak removes itself from your personal computer right after execution, there are a few things you must do. First of all, you need to figure out what you want to do with the decrypted files. Afterward, you must install a reliable malware removal tool to make sure that all threats are deleted. Even though you do not have to delete FessLeak, other threats could be active. In addition, you need to upgrade your virtual security and keep up with all updates, to ensure that no security vulnerabilities can be exploited to infiltrate FessLeak or other threats. Finally, we remind you that you need to be cautious when browsing the web, because security threats can hide behind every corner.
