More Information

Troj/Regile-A is a backdoor for the Linux platform.

If Troj/Regile-A is executed with root privileges it will append the following line to the file /etc/passwd:

eregli::0:0:system user for Memory(by ooze):/:/bin/sh

This creates a user account called eregli with no password and root privileges.

Troj/Regile-A opens port 67 and waits for a connection. Once connected, the intruder has full shell access to the system
