Adversary tradecraft that uses built-in operating system binaries and trusted tools to achieve attacker objectives without dropping new files.
PowerShell, WMI, certutil, mshta, regsvr32, rundll32 — all signed Microsoft binaries that can download, decode, or execute payloads. The LOLBAS project catalogues over 200 such binaries. Defence relies on behavioural detection (command-line and parent-process anomalies), not file hashes.
See our web application penetration testing, API security testing, network penetration testing, and cloud security audit services for how we test for and defend against this class of issue.
