The Enjey Crypter Ransomware is a Trojan that locks your files through an encryption routine that reorders their data according to a specified algorithm. The rest of this Trojan's payload drops messages asking you to make payments for restoring your content, which should be treated as a last-resort option if you consider it at all. Along with keeping backups that make its attacks ineffectual, you can use updated, professional anti-malware software to detect and delete the Enjey Crypter Ransomware during any infection attempts.

A Document Written with a Trojan Code

The original meaning of a 'Trojan horse' references the mythic concept of soldiers ambushing their enemies via hollowed horses. Since the dawn of threats, the term has been co-opted to apply to a heady range of threats, including ransom-based Trojans like the Enjey Crypter Ransomware. The Enjey Crypter Ransomware, for its part, takes its classification namesake to heart in how it distributes itself.

The Enjey Crypter Ransomware conceals its primary executable as a fake Word document or DOC file, although it retains the '.exe' extension. Users without extension-viewing enabled may launch the Enjey Crypter Ransomware by mistake after exposing themselves through methods like e-mail attachments or Exploit Kit-delivered downloads. The Enjey Crypter Ransomware proceeds with a primary attack and a ransoming function, both of which malware experts rate as standard to this type of threat.

The Enjey Crypter Ransomware encrypts files of formats like DOC, TXT, or JPG with a still-unknown cipher (with AES being the most popular, but not only, choice of threat actors, to date). Each file it locks has an additional extension inserted ('.encrypted.contact_here_me@india.com.enjey') that includes the con artist's e-mail contact. The encrypted content must be decrypted with the appropriate key and software before they're usable again.

The Enjey Crypter Ransomware also places a text file ('README_DECRYPT.txt') on the Windows desktop. The instructions therein give the victim an option for paying Bitcoins to ransom their data back, although using a cryptocurrency prevents you from canceling transactions that see no decoding responses from the con artist.

Putting Bad Documents into the Shredder

File-encryption Trojans may compromise new PCs by way of e-mail spam campaigns that imitate package notifications or internal department communications. Enabling visible file extensions and scanning new files like the Enjey Crypter Ransomware will let your security solutions detect the threat before encryption-locked content becomes an issue. Malware experts have found no working decryption solutions for the Enjey Crypter Ransomware, although victims are welcome to solicit assistance from the cyber security industry in developing freeware decoders (such as by providing samples of the Trojan and locked data).

The Enjey Crypter Ransomware's campaign is new, and accurate detection rates for this threat are overall low among most brands of anti-malware products. Update your security software when possible to optimize their detection of newly-made threatening software, and back your valuable files up to other PCs when practical. Removing the Enjey Crypter Ransomware and disinfecting your PC will not unlock any files automatically, which is why access to backups remains valuable.

Acting as a sheep in wolf's clothing, the Enjey Crypter Ransomware seeds itself through imitating the contents and formats of 'safe' files. PC users taking simple elements like file names and icons for granted continues being a massive vulnerability that con artists are only too eager to exploit for Bitcoins.
