Getting Started with WMI Weaponization – Part 1

Introduces Invoke-WMIFS, a PowerShell module that abuses a custom WMI class to stash files as Base64 chunks inside the CIM repository, a quota-aware covert storage trick for evasive operations.

Explains WMI event-driven persistence through filter, consumer, and binding triples, contrasting polled intrinsic events with push-based extrinsic events for launching commands on user logon.

Replicates ntds.dit dumping with pure WMI Win32_ShadowCopy calls instead of vssadmin, remotely snapshotting a domain controller to pull password hashes while trimming the tool-based IoC footprint.

Surveys administrative WMI classes such as Win32_Service for remote service creation and system changes, positioning WMI as a quieter alternative channel for post-exploitation administration.

Teaches enumerating the 1,500-plus WMI classes on a system with Get-CimClass, then dissecting properties and methods of classes like Win32_Process to find attacker-useful functionality.

A pentest shows Claude refuses to build an LSASS dumper, but local DeepSeek and uncensored Qwen models produce a working XOR-encrypted minidumper, making AI-assisted EDR evasion nearly effortless.
