Stop burning RDP persistence with 4732 alerts. Bypass the "Remote Desktop Users" group entirely. GUI access only requires: - SeRemoteInteractiveLogonRight (Inject SID via secedit) - RDP-Tcp listener permissions (Modify CIM class) OPSEC: Trades 4732 for 4704. Most SOCs don't tune 4704 with the same aggression. h/t @Cptjesus for the concept.

shipping: WinSSHound maps SSH access in AD as BloodHound paths. because Windows OpenSSH cheerfully ignores your "Deny Logon" GPOs (pre-2025) and on a default sshd_config every Authenticated User in the domain can walk right in. Why? Because Microsoft. github.com/1r0BIT/WinSSHound

Finally, it is published 😁 Making Vulnerable Drivers Exploitable Without Hardware - my latest research on driver vulnerability hardware-gating, explaining the concept of hardware-dependent code and diving deep into creative deployment techniques - software-emulated phantom devices, driver restacking, and forced driver replacement — all explored through the lens of Bring Your Own Vulnerable Driver (BYOVD) attacks: atos.net/wp-content/uploads/…
