eCh0raix ransomware campaign aimed at QNAP Network Attached Storage (NAS) devices used for backups and file storage. The attackers hack servers with weak passwords and require a ransom of 0.05–0.06 BTC. The ransomware has been reported to target the following QNAP NAS devices: QNAP TS-231, QNAP TS-251, QNAP TS 253A, QNAP TS 253B, QNAP TS-451, and QNAP TS-459 Pro II.
Ch0raix is a compact Go program (the code takes up no more than 400 lines). Authors of the ransomware picked up passwords by brute forcing the servers. It communicate with with C&C which are located on TOR network via SOCKS5 proxy from where it downloads the ransom note, a RSA public key to encrypt the key it employs when encrypting its victim's files, and to provide the attackers with real-time insight on the malware's activity. It however, does not send system information to its server.
