This is interesting. No, the asterisk is not supposed to be any special. Only the colon, linefeed, and NUL characters should be problematic with the above approach (well, maybe also CR and EOF on non-Unix platforms). What implementation/revision of the NTLM hash support patch to JtR did you use? What platform did you run this on? Can you please post a PWDUMP-style line for the LM/NTLM hashes that correspond to the above passwords? Are you able to login to the target system using the "Real Password" above?
