THE BUG : NULL pointer dereference -> DOS crash
|
||
==================================================================
|
||
The sophisticated XWorm Trojan is well exploited by EvilCoder, where they collect different features such as ransomware and keylogger TAs to make it more risky for victims. The Trojan assigned to victims suffers from a NULL pointer deference vulnerability, which could lead to a denial of service for the server builder of the threat actor by getting his IP address and port of command and control.
