competition-forensic-timeline

competition-forensic-timeline is a skill for Claude Code, Codex from 2233admin/reverse-skill-evolver. It costs 109 tokens per session (674 once invoked), scanned A, a copy of competition-forensic-timeline, MIT.

A specialist guide for building a forensic timeline in a controlled capture-the-flag investigation environment. DFIR means digital forensics and incident response: examining computer evidence to reconstruct what happened.

In plain words
What is it for?
Normalizing timestamps and identifiers, correlating artifacts, tracing execution and persistence, and reconstructing an incident chronology after the sandbox workflow has been established.
Why use it?
It helps combine evidence from logs, network captures, disks, memory, email, and browsers into one ordered account while separating confirmed events from guesses.

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

competition-forensic-timeline 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 3d ago.

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.

Competition Forensic Timeline

Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.

Use this skill when the hard part is not finding one artifact, but turning many artifacts into one replayable chronology.

Quick Start

  1. Pick the smallest reliable anchor: first execution, first logon, first network session, first file write, or first mailbox action.
  2. Normalize timestamps, time zones, hostnames, users, process IDs, message IDs, and file paths before correlating.
  3. Build one minimal chain from foothold to persistence, execution, access, or exfiltration.
  4. Separate confirmed event order from inferred gaps.
  5. Reproduce the decisive timeline segment that yields the artifact or privilege conclusion.

Workflow

1. Establish Timeline Anchors

  • Collect only the active surfaces: EVTX, Sysmon, registry, Amcache, prefetch, browser artifacts, mail traces, PCAPs, memory, or filesystem metadata.
  • Record clock source, timezone, and any drift or truncation that could reorder events.
  • Link shared identifiers across sources: PID, logon ID, GUID, message ID, hostname, username, IP, or hash.

2. Correlate The Execution Graph

  • Track process tree, service or task creation, network sessions, file writes, registry changes, mailbox rules, or token use as one path.
  • Distinguish causal edges from coincidence by matching identifiers and adjacency, not just nearby timestamps.
  • Keep raw artifact and parsed summary side by side so every step can be traced back.

3. Compress To The Decisive Story

  • Reduce the timeline to the smallest sequence that proves initial access, persistence, lateral movement, collection, or artifact recovery.
  • Call out missing validation steps separately instead of mixing them into confirmed chronology.
  • If the task becomes mainly about malware config extraction or a Windows pivot edge, switch to the tighter specialized skill.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
