Hackers often target Linux SSH servers due to their widespread use in hosting critical services, and the following loopholes make them vulnerable, providing opportunities to hackers for unauthorized access and potential exploitation:-.
Cybersecurity researchers at AhnLab Security Emergency Response Center recently identified that hackers actively attack the Linux SSH servers to deploy scanner malware.
Threat actors target poorly managed servers, seeking IP and SSH credentials for DDoS and CoinMiner malware.
IP scanning identifies active SSH ports, followed by brute force attacks.
More CoinMiners mean increased cryptocurrency mining.
DDoS attacks grow in power with more controlled bots, and to install more malware, actors need target information besides DDoS and CoinMiners, malware scans, and attacks vulnerable systems.
SSH scanner malware DDoS bots and CoinMiners may be installed.
Some actors install scanners, selling breached info on the dark web.
Here below, we have mentioned all the common malware that is installed in attacks against poorly managed Linux SSH servers:-.
Threat actors deploy malware on Linux servers after logging in with stolen SSH credentials.
Threat actor scans for active SSH systems using stolen credentials for malware installation.
The CPU core check command confirms the successful login.
The actor downloads a compressed file with a port scanner and SSH attack tool.
To safeguard cybersecurity, researchers recommended the following mitigations:-.
