The $ucyLocker Ransomware is a Trojan that locks your files by using Hidden Tear-based encryption features. Even though its attacks include a ransoming message for purchasing a data-decrypting service, malware experts warn against paying since the Trojan omits features that are integral to the recovery process. Keep backups to prevent this Trojan from causing irreversible damage, and use anti-malware protection to block or uninstall the $ucyLocker Ransomware.

The All-Important Missing Molecules in a Drop of Hidden Tear

Threat actors without the drive to make anything better resort to creating minor modifications of very well-explored threats with code that's subject to easy plundering frequently. This fact is a point of origin for file-encrypting Trojans particularly, which con artists can create in a matter of minutes, after getting access to the widely-circulated code of Hidden Tear. However, their editing to that baseline code, sometimes, causes more troubles for the people they attack, as malware experts assert with the $ucyLocker Ransomware.

The $ucyLocker Ransomware, referred to by some sources as theVapeHacksLoader Ransomware, searches an infected PC for documents, pictures, and equally non-essential, but personally valuable, formats of media. It targets every file fitting its definitions with an AES cipher that locks them from opening. The $ucyLocker Ransomware's threat actor also chose to add the '.WINDOWS' extension onto their names, which is a unique string not shared with other Hidden Tear revamps.

The usual profit-generating features also are in evidence, such as text messages and HTML pop-ups asking the user to pay Bitcoins to get access to the decryption feature. Victims doing so will not be able to restore their files; the $ucyLocker Ransomware doesn't save the decryption data and doesn't check to verify the transaction. Malware experts also emphasize that, since the $ucyLocker Ransomware uses Bitcoin ransoms, refunds will not be available without the threat actor's highly unlikely consent.

Keeping a File-Locker from Taking You for a Sucker

The $ucyLocker Ransomware is a valuable example of how threat actors can take a given definition of a threat and modify it just enough to make it even worse for the people it attacks. Even when these changes consist of nothing more than deleting previous features, the result is an encryption attack that can damage your files permanently. Decryptors for Hidden Tear may unlock some of the files that the $ucyLocker Ransomware attacks, but malware analysts also encourage keeping backups as a fallback position for when decryption isn't possible.

While malware analysts can't corroborate any ongoing distribution models in the $ucyLocker Ransomware campaign, its threat actor could install it through traditional methods, like documents attached to e-mail spam, free software bundles, or a website's drive-by-download scripts. Disabling macros, scanning downloads before you open them, and disabling content like JavaScript and Flash will help you block these attacks. Many anti-malware products also remove the $ucyLocker Ransomware and other Hidden Tear variants without any issues.

Stopping a Trojan like the $ucyLocker Ransomware from gaining a foothold on your computer is more than just a convenience, it's a defensive position to protect your files from attacks. Just as in real warfare, recovering from losses will cost the defending party more than drawing a line in the sand.
