Process Ghosting — EDR Evasion

The technique Process Herpaderping attempts to perform evasion by performing modification of the file (image tampering) which creates the process on a windows system. Deleting also the file during the creation of the process can have the same results. Even though some endpoint products have mature over the years and are able to detect complex threats organizations should constantly test the capabilities of their solution and should find alternate methods of detection even for the same technique.

Alternative Process Injection

Process injection is a well-known defense evasion technique that has been used for decades to execute malicious code in a legitimate process. Until now, it is still a common technique used by hackers/red teamers.

Process Ghosting

This article describes a new executable image tampering attack similar to, but distinct from, Doppelgänging and Herpaderping. With this technique, an attacker can write a piece of malware to disk in such a way that it’s difficult to scan or delete it — and where it then executes the deleted malware as though it were a regular file on disk. This technique does not involve code injection, process hollowing, or Transactional NTFS (TxF).
