WininiCrypt – recently emerged ransomware virus

The picture of WininiCrypt

WininiCrypt is a file-encrypting virus that appends .[cho.dambler@yandex.com] file extension to the target files. Once all the data is locked with a sophisticated algorithm, malware delivers a ransom note in HOW_TO_BACK_FILES.html file.

Typically WininiCrypt virus spreads as an obfuscated file in the emails. As soon as a user opens it, malware enters the system. Then it creates a new process in the %WINDIR%\System32\cmd.exe directory and drops an executable file called sdelete.exe.

WininiCrypt ransomware might also modify proxy settings, queries sensitive IE security settings, install suspicious files, and alters or creates new Windows Registry entries. When it strengthens its presence, crypto-malware starts scanning the system looking for the targeted data for the encryption.

Apart from encrypting the files, the virus also deletes Shadow Volume Copies[1] by executing the command:

vssadmin Delete Shadows /All /Quiet

Thus, it means that data recovery after ransomware attack might be nearly impossible without specific decryption tool. Undoubtedly, hackers offer to obtain it from them. However, paying the ransom and hoping that cyber criminals will keep their word is naive.

After ransomware attack, you should focus on your computer’s state and remove WininiCrypt together with its malicious components. Virus elimination won’t help to restore your files, but you will be able to use backups, extract valuable data from emails and use alternative recovery methods.
