Muhstik Botnet Exploits the Latest Web Logic Vulnerability for Cryptomining and DDoS Attacks

Summary: On April 28, 2019, Unit 42 discovered a new variant of the Linux botnet Muhstik exploiting the WebLogic vulnerability CVE-2019-2725, disclosed five days earlier, to install itself on vulnerable systems. The botnet, active since March 2018 with worm-like self-propagation, infects Linux servers and IoT devices to run cryptocurrency mining and DDoS attacks, and the captured exploit payload contained a single shell command to download wl.php from IP address 165.227.78[.]159.

What's compelling: Muhstik added the exploit within five days of disclosure, and Oracle's emergency patch released April 26, 2019 was confirmed to block this variant - the gap between disclosure and weaponization is measured in days, not weeks.
