What is Torchwood ransomware? And how does it implement its attack?
Torchwood ransomware is a crypto-virus created to lock important files in a targeted computer. It uses either the .TORCHWOOD or .TRCHWD extensions in marking the files it encrypts. This new crypto-malware seems to be targeting Russian-speaking users as its ransom note is written in Russian.
The instant it invades a computer, it drops its malicious payload in one of the system folders and launches it. It will also connect the infected computer to a remote server controlled by the attackers. From this remote server, the crypto-malware downloads more of its malicious components. After that, it uses an information gathering module in order to gather data about the infected system and its user. The obtained data, along with some of the malicious components are then used for stealth protection. In addition, it also modifies some Registry entries so that it can run on every system boot. Once all these modifications are applied, it starts the encryption process by scanning the computer for files with certain extensions. After it finds the files it’s looking for, it encrypts them using the AES encryption algorithm. It then marks the encrypted files with the .TORCHWOOD or the .TRCHWD extension. Following encryption, it opens a file named “ИНСТРУКЦИЯ_ПО_РАСШИФРОВКЕ_ФАЙЛОВ.txt” which contains the following content written in Russian:
