説明

Not sure if this is even worth addressing, but I just noticed on an engagement today that many of the hosts that never finish are in fact finishing, but are multi-homed. Here is example output from a system that I RDP'ed into to verify that all IPs were assigned to the same host:

cme smb 1.2.3.0/24 -u someuser -p 'somepassword' -M mimikatz

調査方針
Investigate the host enumeration and completion tracking logic in CrackMapExec, specifically in the smb module. The issue is that multi homed hosts (same hostname with multiple IPs) cause duplicate entries and the waiting list never clears. Consider deduplicating hosts by hostname or adding a check to ignore already processed hostnames. See the log output for patterns where the same hostname (DOMAIN) appears with different IPs and repeated mimikatz output.
