SimpleRmiDiscoverer is a JMX RMI scanning tool for unsecured
(without enabled authentication) instances of JAVA JMX. It does not
use standard Java RMI/JMX classes like other available tools but
rather communicates directly over TCP. The tool is written in Java
and is very useful in red teaming operations because JVM is still
ubiquitous in corporate environments. It can be executed by
unprivileged (non-admin) users.
