offensive-keylogger-arch SKILL.md skillA
offensive-keylogger-arch from miosa-osa/osa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add miosa-osa/osa/offensive-keylogger-arch@git:20260913.e13b6b8Pins git:20260913.e13b6b8 in mdr.lock. Pin the fingerprint instead.

Low-level keylogger architecture design: kernel driver hooks (WH_KEYBOARD_LL, SetWindowsHookEx), ETW-based input capture, user-mode vs kernel-mode approaches, stealth techniques, and data exfiltration. Use for understanding input capture mechanisms, EDR evasion research, or malware architecture analysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SKILL: Novel research ## Metadata - **Skill Name**: keylogger-architecture - **Folder**: offensive-keylogger-arch - **Source**: https://github.com/SnailSploit/offensive-checklist/blob/main/Low-level%20Keylogger%20architecture_.md ## Description Low-level keylogger architecture design: kernel driver hooks (WH_KEYBOARD_LL, SetWindowsHookEx), ETW-based input capture, user-mode vs kernel-mode approaches, stealth techniques, and data exfiltration. Use for understanding input capture mechanisms, EDR evasion research, or malware architecture analysis. ## Trigger Phrases Use this skill when the conversation involves any of: `keylogger, keyboard hook, WH_KEYBOARD_LL, SetWindowsHookEx, ETW, kernel driver, input capture, low-level keylogger, malware architecture, stealth, exfiltration` ## Full Methodology Case study of different keylogger implementations, how to implement them and their individual IOCs. --- ## SetWindowHookEx Majority of malware uses user32.dll!SetWindowHookEx to create a global hook event. this modifies an internal structure in `win32k.sys`. …

How to install
mdr add miosa-osa/osa/offensive-keylogger-arch@sha256:19c82fce1a362568The line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
