Shellshock, also known as Bashdoor is a family of security bug in the widely used Unix Bash shell, the first of which was disclosed on 24 September 2014. Many Internet-facing services, such as some web server deployments, use Bash to process certain requests, allowing an attacker to cause vulnerable versions of Bash to execute arbitrary commands. This can allow an attacker to gain unauthorized access to a computer system.

Mimikatz version
> The way to forge a Golden Ticket is very similar to the Silver Ticket one. The main differences are that, in this case, no service SPN must be specified to ticketer.py, and the krbtgt ntlm hash must be used.
