An unknown threat actor is brute-forcing Linux SSH servers to install a wide range of malware, including the Tsunami DDoS bot, ShellBot, log cleaners, privilege escalation tools, and an XMRig coin miner.
Network administrators typically use SSH to manage Linux devices remotely, performing tasks such as running commands, changing the configuration, updating software, and troubleshooting problems.
AhnLab Security Emergency Response Center recently discovered a campaign of this type, which hacked Linux servers to launch DDoS attacks and mine Monero cryptocurrency.
The attackers scanned the Internet for publicly-exposed Linux SSH servers and then brute-forced username-password pairs to log in to the server.
To defend against these attacks, Linux users should use strong account passwords or, for better security, require SSH keys to log in to the SSH server.
