It also spells out signature verification, baseline diffing to spot newly added entries, and offline analysis of a disk image with the `-z` flag. A Python script ships with it. It runs `autorunsc64.exe` with `-a * -c -h -s -nobanner *`, writes the output to CSV and flags what looks wrong: unsigned binaries, missing metadata, paths under `\Temp\` or `\AppData\Local\Temp`, and launch strings using `powershell`, `wscript`, `mshta` or `regsvr32`. The script expects Python 3.9+. Reputation checks need a VirusTotal API key, and the compare function needs a clean baseline export taken beforehand. No baseline means nothing to diff against, so pull one before you start on an infected host. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-malware-persistence-with-autoruns -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/analyzing-malware-persistence-with-autoruns/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/analyzing-malware-persistence-with-autoruns/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-malware-persistence-with-autoruns -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/analyzing-malware-persistence-with-autoruns/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-malware-persistence-with-autoruns -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/analyzing-malware-persistence-with-autoruns/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install mukul975/Anthropic-Cybersecurity-Skills analyzing-malware-persistence-with-autoruns ``` 2. **Manually: put the files in place** - File: `.github/skills/analyzing-malware-persistence-with-autoruns/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-malware-persistence-with-autoruns -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/analyzing-malware-persistence-with-autoruns ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/analyzing-malware-persistence-with-autoruns/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-malware-persistence-with-autoruns -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/analyzing-malware-persistence-with-autoruns/SKILL.md ## When to use it - enumerate every autostart point on a compromised host - separate unsigned entries from Microsoft-signed ones - spot LOLBin launch strings in autostart entries - diff current Autoruns output against a clean baseline - analyze autostart entries from an offline disk image ## Example prompts - scan autostart with autorunsc and list the suspicious entries - compare the current Autoruns export with the baseline and name new entries - analyze autostart points in a disk image offline ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

Digital signature verification filters Microsoft-signed entries. The compare function identifies newly added persistence via baseline diffing. VirusTotal integration checks hash reputation. Offline analysis via -z flag enables forensic disk image examination. ## When to Use - When investigating security incidents that require analyzing malware persistence with autoruns - When building detection rules or threat hunting queries for this domain - When SOC analysts need structured procedures for this analysis type - When validating security monitoring coverage for related attack techniques ## Prerequisites - Sysinternals Autoruns (GUI) and Autorunsc (CLI) - Administrative privileges on target system - Python 3.9+ for automated analysis - VirusTotal API key for reputation checks - Clean baseline export for comparison ## Workflow ### Step 1: Automated Persistence Scanning ```python ```` END THIRD-PARTY FILE 4309524bf41135d7 The third-party file has ended.
