The Fuck_You Ransomware is a Trojan that uses encryption technology to block your files and make them unreadable by other applications. Its attacks are theoretically recoverable by a decryptor, which the Trojan's threat actors sell for a Bitcoin ransom. Since this recovery method isn't guaranteed and rewards illicit behavior, malware experts advise that you uninstall the Fuck_You Ransomware with the proper anti-malware tools and use free decryption applications or backups for your data recovery.

The Trojan that Tells You What It Thinks of You

Since different groups of threat actors have either rented or 'borrowed' the Hidden Tear's code for conducting various file-ransoming campaigns, a new version of it can be called original scarcely. Notwithstanding that caveat, some threat actors manage to differentiate themselves in minor ways from others using almost mirror-image Trojans against businesses and recreational PC users. The latest of this number includes the individuals deploying the Fuck_You Ransomware, which, already, may be collecting ransoms.

As a Hidden Tear-based program, the Fuck_You Ransomware selects files for attacking according to an internal whitelist that can include formats such as Word's '.DOC' documents or '.JPG' images. It encrypts these files on your PC automatically and may include any local network-accessible drives in its scans. The AES-based encryption technique renders your media unable to open until you decrypt it back to normal. The Fuck_You Ransomware also generates a Notepad file on your desktop dynamically with instructions (including the profanity which gives it its name) for paying a 50 USD equivalent in Bitcoins before contacting the threat actor's e-mail address, most likely for receiving a decryptor.

Preserving Your Files against the Mouthiest of Threats

While its infection methods are unknown, the Fuck_You Ransomware does disguise itself with incorrect descriptions and other information that could lead to a victim believing it to be part of the Windows OS. Since the Fuck_You Ransomware's ransoming demands are relatively small, malware experts are estimating that its attacks aren't targeting well-funded businesses that would be willing to pay thousands of dollars to recover their servers' contents. Recreational PC users may be at risk via spam e-mail attachments, a website's embedded vulnerabilities (which often trigger with the help of Flash or JavaScript), or even torrents.

There are some decryption solutions available for anyone needing to recover a Hidden Tear-encrypted content without paying a ransom. Most users also should consider backing any media of importance to another drive not vulnerable to an attack by file-encrypting Trojans. Removing the Fuck_You Ransomware with dedicated anti-malware apparatus, while as viable for this threat as with other versions of Hidden Tear, doesn't reverse any of its encryption damage.

The Fuck_You Ransomware is blunter in tone than most of its kind, but all file-encrypting threats carry the same, core message. Money is more important to the con artists than your files, which is why you should stop to think of the consequences before giving them something out of a hope of getting anything in return.
