Encryption Trojan attacks Spain and FranceRussian anti-virus company Doctor Web has registered an ongoing massive spread of the encryption malware Trojan.ArchiveLock across PCs outside Russia. The program, dubbed Trojan.ArchiveLock.20, is infecting increasingly more computers in France and Spain.
Last August, Doctor Web issued a warning about Trojan.ArchiveLock encryption malware. This program uses the archiver WinRAR to encrypt files. To spread the malware, criminals mount a brute force attack via the RDP protocol on target machines. Once connected to the attacked PC, cybercriminals launch the Trojan. After gaining control, Trojan.ArchiveLock.20 copies the encryption application to one of the system folders.
Trojan.ArchiveLock.20 then creates a list of files to be encrypted, empties the Recycle Bin, and deletes all backups stored on the computer. The Trojan uses the console version of WinRAR to place files on the compiled list into password-protected, self-extracting archives and employs a special utility to delete original files, after which they simply can't be restored.
