First Seen: May 12, 2017
OS(es) Affected: Windows

The FuckTheSystem Ransomware is a file-locking Trojan based on the FTSCoder family and can block your media, such as pictures or documents. Its other attacks include filename changes and pop-ups, the latter of which may deliver ransom messages. Malware experts rate this threat as easily decryptable, and victims should be able to recover their files freely after deleting the FuckTheSystem Ransomware with any good anti-malware program.

An Extortionist's Alternative System for Making Money without Working

Threat actors are retaining an interest in using the .NET Framework code for delivering encryption attacks with little development time, but this choice also renders their products potentially more susceptible to analysis. Fresh examples include the FuckTheSystem Ransomware and the Haters Ransomware, both members of the FTSCoder family of file-encrypting threats. Unlike the Haters Ransomware, the FuckTheSystem Ransomware doesn't try to mislead the victim about its identity, and, instead, contents itself with locking files and loading pop-ups for ransoming.

Malware experts are rating the FuckTheSystem Ransomware as being still in development, with any means by which it might install itself on a victim's PC not known. Infection strategies to watch for include e-mail spam, macro-based document exploits, and exploit kit-based attacks hosting through corrupted or hacked websites. Symptoms a victim sees afterward include being unable to use a potentially wide variety of file formats, as a result of the FuckTheSystem Ransomware's encryption feature.

The FuckTheSystem Ransomware scans your drives for documents and other files that it can encipher with an algorithm that reorganizes their data, stopping other programs from being able to read them. It also provides a superficial '.anon' extension for the victim to identify them, and, then, loads a Windows message box. This pop-up is likely to serve as a vehicle for carrying demands for payment to get the decryption password and restore your files, although current releases of the FuckTheSystem Ransomware show no ransom instructions.

A Personal System for Making Ransoming Trojans Outdated

The FuckTheSystem Ransomware shares one of the major vulnerabilities also notable with its relative, the Haters Ransomware: a file-unlocking password that's fixed in its internal code as a non-variable value. For the FuckTheSystem Ransomware, the password is 'Hexobon,' which victims can enter into its pop-up field to force the decryption feature to run. Like many .NET Framework Trojans, the FuckTheSystem Ransomware also can have the file-locking aspects of its payload reversed by free utilities provided by various PC security organizations for no fee.

Paying to get your files back from threats like the FuckTheSystem Ransomware isn't always necessary, but it retains its classification as a significant security risk until its full removal. Use anti-malware products to fully identify and delete the FuckTheSystem Ransomware, which usually will use inaccurate filenames or directories to protect itself. Standard anti-malware programs also may block the threats most likely of distributing the Trojan, including drive-by-downloads that malware experts often confirm for occurring automatically.

New Trojans meant for damaging your local files are being identified with high regularity, and not all of them use encryption strategies as simple as the FuckTheSystem Ransomware's function. While backing up your hard drive is a potentially tedious chore, it's still clearly preferable to losing money just to get a password.
