Threat details

GreedyAntd is delivered manually, with Pacha scanning the Internet for vulnerable WordPress or PhpMyAdmin instances before deploying several exploits for known vulnerabilities to gain access to the underlying server. Once this is done they will drop a backdoor through which GreedyAntd is installed.

Once delivered, GreedyAntd will create a Systemd service to gain persistence before creating a proxy service to mask disguise it's operations. It will then deploy a heavily modified XMRig variant using a configuration file downloaded from a command and control server. A separate list is also downloaded and used to terminate other mining processes on the system.
