As far as I can tell "Assault on 13th Labour" are attacking the wrong cipher.

64/12/8
This is VERY standard notation for the encryption used. It means that when it's being processed, 64 bits of the text are processed at a time. They are processed 12 times and that the key used to process them is 8 bytes (64 bits) long. This makes it almost certain that it's RC5-64 encryption.
Each block is processed 64 bits at a time, for 12 rounds, using an 8 byte key.
The source has been verified by people who were actually involved in the original d.net assault on RC5-64 as a valid port of RCCRYPT 1.4 or 1.6. All of the clients used in this attempt (even those prior to mine) have been based upon the same premise - that Von's hint of RCCRYPT is the appropriate pointer. In actual fact, RCCRYPT is technically RC5-128 not RC5-64, but we are setting that aside for the moment - as this would mean the Von's hint is incorrect.
