extracting-browser-history-artifacts

extracting-browser-history-artifacts is a skill for Claude Code, Codex from adriannoes/awesome-agentic-ai. It costs 36 tokens per session (2,928 once invoked), scanned A, original, MIT.

A forensic workflow for recovering browser records such as history, cookies, cached files, downloads, and bookmarks from Chrome, Firefox, and Edge. It reads the browser databases and profile files where this activity is stored.

In plain words
What is it for?
Use it to investigate phishing, insider threats, suspected data theft, or visits to malicious websites, and to correlate web activity with other evidence.
Why use it?
Browser activity is spread across several files and database formats, so useful evidence can be easy to overlook or interpret incorrectly.

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

extracting-browser-history-artifacts 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), 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.

Extracting Browser History Artifacts

When to Use

  • When investigating user web activity as part of a forensic examination
  • During insider threat investigations to establish patterns of data exfiltration
  • When tracing user visits to malicious or policy-violating websites
  • For correlating browser activity with other forensic artifacts and timelines
  • When investigating phishing attacks to identify which links were clicked

Prerequisites

  • Forensic image or access to user profile directories
  • SQLite3 for querying browser databases
  • Hindsight, BrowsingHistoryView, or DB Browser for SQLite
  • Knowledge of browser artifact file locations per OS
  • Python 3 with sqlite3 module for automated extraction
  • Understanding of Chrome, Firefox, and Edge storage formats

# Copy artifacts to working directory

What ships with it

Changes

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.
