rp_ransomware-file-encryption-150x150.jpgTrojan.Ransomcrypt is a Trojan horse that creates several different files in an infected computer and once it has control over the victim PC, scans for and encrypts imprortant data from the user. It has several different variants – T, S, R and the primary Trojan.Ransomcrypt version. The specific strength of this trojan is that it can scan for a wider range of file formats than other ransomware viruses. Experts advise affected users to immediately follow the instructions provided on the bottom of this page. It is highly recommended to remove any files that this trojan has created on the computer as fast as possible and try to decrypt their files using some of the methods linked at the end of this article.

Trojan.Ransomcrypt – How Did I Get Infected

The Trojan.Ransomcrypt variants are primarily distributed via spam mail campaigns. A spam email may contain several different files and resemble different reputable services that may fool users to think they are perfectly safe by resembling a reputable company or a person as a sender. One good example was the Windows 10 Fake Upgrade email spam. Users are strongly advised to beware and use external mail software that has spam filters. Microsoft Outlook and Mozilla Thunderbird are one of the most preferred email address managing software out there and some users prefer them.

Trojan.Ransomcrypt – More about It

Symantec researchers have identified several different variants, besides the main variant of this trojan. Once executed on the computer, the main variant of this infection creates this file and sets it as a wallpaper:

→SystemDrive\vsworkdir\shantazh.jpg

After this is done, the trojan horse begins to scan the computer for the most opened and important files in the user PC:

→.doc .jpg .rar .zip .txt .rtf .jpeg .html .htm .php .eml .3gp .7z

.3gp .7z

After establishing which files are important for users, the malicious program then encrypts all of the detected files on scan and copies them with an added .vscrypt extension to them. After doing so, the trojan then deletes the original files. What is good news about the original variant is that it uses one decryption key for all of the encrypted files, similar to the .bitcrypt extension ransomware.

After it has finished with the encryption of the targeted files, the cyber threat then changes the wallpaper to a message in Russian and restarts the infected PC. The message states the following:

“Hello, I am a Trojan encoder, more specifically one of its variants ::) my author is a person whose nickname is KOPPEKTOP and he will gladly sell you a decypher for the files that I succeeded to encrypt on your computer for the small sum of 10 dollars it is around 350 rubles here are the details to connect to my account
Mail: otrazhenie_zla@mail.ru icq 481095
oh yes i almost forgot – do not clean the files with vscrypt extensions because taking them back will become impossible
Good luck yours trully Trojan encoder and KOPPEKTOP”
