What is OnyxLocker ransomware? And how does it carry out its attack?


OnyxLocker ransomware is a data-encrypting virus that attaches a “.onx” suffix to every file it encrypts. It isn’t known yet if it belongs to any ransomware groups, although based on the analysis done by security experts, it uses a sophisticated encryption algorithm in locking its targeted files. It seems to be targeting Russian-speaking users since its ransom note is written in the Russian language.

The instant it invades a computer, OnyxLocker ransomware will begin to carry out its nefarious attack by dropping 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 .onx extension. Following encryption, it drops 10 identical ransom notes like “Прочти меня! 0 .txt”, “Прочти меня! 1 .txt”, and so on, which contains the following content written in Russian:
