Invoke-Apex is a PowerShell-based toolkit consisting of a collection of techniques and tradecraft for use in red team, post-exploitation, adversary simulation, or other offensive security tasks. It can also help identify lapses in "malicious" activity detection processes for defenders.
Each technique or method in the toolkit is mapped back to a Mitre ATT&CK Technique ID where applicable, and the techniques and modules which they can be found in can be viewed with the Invoke-MitreReference -Help command. See the section "The Mitre ATT&CK Reference Component" for more info!
Invoke-Apex is a work-in-progress, so updates to modules and additional capability can be expected regularly as time allows.
