ShuckNT is the script of Shuck.sh online service for on-premise use. It is design to dowgrade, convert, dissect and shuck authentication token based on Data Encryption Standard (DES).
I have tested this with a weak NT hash (Password) and generated the NTLMv1 challenge on shuck.sh however this doesn't list the NT hash, it only listed ************FF. If I try the same hash with the online shucker this works. I have a single NT hash in a text file, appended the ":1" as HIBP uses, reversed the hash and sorted. When running the tool it shows 1 candidate it loaded but does reveal the NT hash.
