Every file gets at least one 1024-byte record holding $STANDARD_INFORMATION, $FILE_NAME and $DATA attributes. Deleting a file clears the InUse flag but leaves metadata intact until a new file reallocates the entry. So MFT analysis recovers names, paths, sizes and timestamps of deleted objects. Four techniques are described. Record parsing with MFTECmd, filtering the CSV by the InUse column. USN Journal analysis by reason codes for deletion and rename events. $LogFile parsing via LogFileParser to find DeallocateFileRecordSegment and DeleteAttribute operations. A Python script pulls readable strings and attribute header remnants out of MFT slack space. You need a forensic image in E01, raw/dd, VMDK or VHDX, MFTECmd or analyzeMFT, and FTK Imager or Arsenal Image Mounter for mounting. CSV output goes into Timeline Explorer or Excel. Python 3.8+ if you run the custom slack-space script. The skill is a procedure, not a packaged command set, so the agent walks through it step by step. ## Requirements - Works with: Slack ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-mft-for-deleted-file-recovery -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/analyzing-mft-for-deleted-file-recovery/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/analyzing-mft-for-deleted-file-recovery/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-mft-for-deleted-file-recovery -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/analyzing-mft-for-deleted-file-recovery/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-mft-for-deleted-file-recovery -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/analyzing-mft-for-deleted-file-recovery/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install mukul975/Anthropic-Cybersecurity-Skills analyzing-mft-for-deleted-file-recovery ``` 2. **Manually: put the files in place** - File: `.github/skills/analyzing-mft-for-deleted-file-recovery/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-mft-for-deleted-file-recovery -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/analyzing-mft-for-deleted-file-recovery ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/analyzing-mft-for-deleted-file-recovery/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-mft-for-deleted-file-recovery -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-mft-for-deleted-file-recovery/SKILL.md ## When to use it - recover deleted file metadata from $MFT records - extract deletion and rename events from the USN Journal - find DeallocateFileRecordSegment operations in $LogFile - read remnants of previous records from MFT slack space - spot timestomping via mismatched $STANDARD_INFORMATION and $FILE_NAME timestamps ## Example prompts - Parse the $MFT from C:\Evidence and list deleted records - Look for file deletion events in the USN Journal - Check MFT slack space for leftovers of previous records ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

Each file is represented by at least one 1024-byte MFT record containing attributes such as $STANDARD_INFORMATION (timestamps, permissions), $FILE_NAME (name, parent directory, timestamps), and $DATA (file content or cluster run pointers). When a file is deleted, its MFT record is marked as inactive (InUse flag cleared) but the metadata remains until the entry is reallocated by a new file. This persistence makes MFT analysis a primary technique for recovering deleted file evidence, reconstructing file system timelines, and detecting anti-forensic activity such as timestomping. ## When to Use - When investigating security incidents that require analyzing mft for deleted file recovery - 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 - Forensic disk image (E01, raw/dd, VMDK, or VHDX format) - MFTECmd (Eric Zimmerman) or analyzeMFT (Python-based) - FTK Imager, Arsenal Image Mounter, or similar for image mounting ``` END THIRD-PARTY FILE a4c5460f11943865 The third-party file has ended.
