incident-response

incident-response is a skill for Claude Code from hypnguyen1209/offensive-claude. It costs 59 tokens per session (2,761 once invoked), scanned A, original, MIT.

A guide for responding to security incidents and investigating digital evidence. It covers collecting data from computers and cloud systems, analysing memory and logs, and reconstructing timelines.

In plain words
What is it for?
Use it for live incident triage, memory forensics, Windows event-log analysis, cloud investigations, ransomware response, anti-forensics detection, and repository-compromise investigations.
Why use it?
It gives investigators a structured way to understand what happened, preserve evidence, contain threats, and investigate attacks such as ransomware or stolen credentials.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

incident-response scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 9 executable files (scripts/cloud_ir_collect.py, scripts/dangling_commit_finder.py, scripts/ebpf_rootkit_hunt.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Incident Response & Digital Forensics

When to Activate

  • Active security incident: triage, scoping, evidence acquisition, containment, eradication
  • Memory forensics — process injection, rootkit (incl. eBPF), credential-theft, network artifacts
  • Windows event-log / artifact timelining and super-timeline reconstruction
  • Anti-forensics detection — timestomping, log clearing, secure deletion, VSS recovery
  • Cloud incident response — AWS/Azure/GCP identity-plane attacks and forensic collection
  • Ransomware / extortion response — hypervisor (ESXi) encryption, backup destruction, fast-dwell intrusions
  • Verifying suspect DFIR tooling used as adversary persistence (Velociraptor CVE-2025-6264)
  • Repository-compromise post-mortem — a poisoned public repo / force-pushed malicious commit / deleted PR (recover via dangling commits + GH Archive + Wayback + Events API; see references/repo-compromise-forensics.md)
