Opsec discipline

OPSEC Discipline

Overview

Decide the detection footprint and cleanup before acting, not after. Every offensive technique in this repo pairs with the telemetry it generates and a detection signature — use that pairing to choose the quieter path and to know what you'll need to clean up.

Before acting, answer three questions

1. Detection — what telemetry does this generate? Which Sigma/EDR rule would catch it? (Each domain skill's OPSEC & Detection table has this.) Pick the lower-noise variant when one exists.
2. Cleanup — what does this touch (files, registry, services, accounts, tickets)? How is it reverted? Stage the cleanup before you create the artifact.
3. Secret hygiene — any captured traffic / output that reaches the model or the report must be redacted at the boundary: python skills/coding-mastery/scripts/_lib/redact_headers.py < exchange.txt (or redact_text()), so Authorization/Cookie/API-key/JWT values never land in context or the report.

Red Flags — STOP, decide OPSEC first

• "I'll worry about cleanup after I'm in" (you won't; decide now)
• "Just paste the raw request/response" (redact secrets at the boundary first)
• "Loudest exploit is fine, it works" (pick the variant with the smaller footprint)
• "Persistence now, document later" (persistence on un-authorized hosts is out — see scope-discipline)
• "The token's only in a log" (a logged secret is a leaked secret — mask it)

Rationalizations

Excuse	Reality
"OPSEC slows me down"	Unplanned noise/loot is how engagements get burned and how data leaks.
"It's an internal tool log"	Logs get shipped, shared, and indexed. Redact.
"Cleanup is a reporting-phase task"	You can't clean what you didn't track. Track at action time.

OPSEC is part of every action, not a phase. Detection-awareness also strengthens the defensive value of the finding (you can tell the client exactly how to catch it).
