Keylogger (Educational / Defensive Detection)
Enable a student to understand keystroke-capture techniques deeply enough to engineer reliable behavioral detections for them.
Keyloggers are a common credential-theft and surveillance component in malware and insider-threat scenarios, yet many defenders do not understand their capture mechanisms well enough to detect them. Without hands-on exposure to how keystroke capture works, blue teams struggle to build reliable behavioral detections. The gap is defensive: understanding the offensive technique to reliably catch it.
**What you'll build**
In an isolated lab, build a minimal educational keylogger to study OS-level input hooking, then pivot fully to the defensive deliverable: a detection tool that identifies keylogging behavior via hook enumeration, suspicious API usage (SetWindowsHookEx), and anomalous process/file activity. Instrument endpoint telemetry (Sysmon/EDR) to alert on capture patterns. The emphasis is detection engineering and safe, ethical study — never deployment against real users.
**Objective** — Enable a student to understand keystroke-capture techniques deeply enough to engineer reliable behavioral detections for them.
**Expected outcome** — A defensive detection tool plus Sysmon/YARA rules that flag keylogging behavior, documented with a controlled lab writeup and ethical-use boundaries.
**Difficulty** — Beginner — basic programming and OS concepts, though the defensive detection layer reaches Intermediate.
**Primary category** — Endpoint Security / Detection Engineering; Secondary = Malware Analysis, DFIR
**Security domains** — Primary = Blue Team; Secondary = Malware Analysis, Red Team (technique study), Digital Forensics, Incident Response
**Technical focus** — OS input hooking, Windows API (SetWindowsHookEx), Sysmon telemetry, behavioral detection, YARA rules, EDR concepts, process/DLL injection awareness, endpoint hardening, insider-threat detection
**Core technologies** — Languages: Python and/or C/C++, PowerShell; Frameworks/Libraries: pynput/pyHook (study), Windows API; Security Tools: Sysmon, YARA, Process Monitor/Explorer, Wazuh/EDR; Cloud/Infra: isolated VM lab (VirtualBox/Hyper-V), snapshots; AI/Data: optional behavioral anomaly scoring; Databases: SQLite/log store
**Where it's valued** — Endpoint security vendors, MSSPs, enterprises with insider-threat programs, DFIR firms, defense
**Careers it builds toward** — Detection Engineer, SOC Analyst, Malware Analyst (entry), Incident Responder, Endpoint Security Engineer
**Framework alignment**
• MITRE ATT&CK: Collection — Input Capture: Keylogging (T1056.001); Credential Access overlap; Defense study of Native API (T1106), Hooking (T1179 legacy/T1056)
• NIST CSF 2.0: Detect (Adverse Event Analysis), Protect (endpoint hardening), Respond
• OWASP: N/A (endpoint/OS focus, not web)
• CIS Controls v8: 10 (Malware Defenses), 8 (Audit Log Management), 13 (Network/Endpoint Monitoring)
**Innovation** — Existing Idea — keyloggers are a classic learning exercise; the defensive-detection reframing is the differentiator and keeps it ethical and career-relevant. Scores: Innovation 4/10, Startup 3/10, Enterprise-Readiness 4/10, Patent = No.
