# DFIR Validation Data

Reference data used for **Volatility 3 / DFIR tool validation** (tool-testing corpus).

## `cridex.vmem`
- **Description:** Public memory-forensics training sample — a RAM image of a Windows XP SP3 x86 host infected with the **Cridex** banking trojan. Long-standing Volatility Foundation reference sample.
- **Acquired:** 2012-07-22
- **Size:** 536,870,912 bytes
- **SHA-256:** `02a63be2fcf3a63446c3c8ca9151aff963f888204d141e46c6be60ddde7c3e8d`
- **Original provenance:** Volatility Foundation memory samples (originally `files.sempersecurus.org/dumps/cridex_memdump.zip`); mirrored here for reproducible validation.

### Known ground truth (for accuracy testing)
- `windows.info` → Windows XP, NtMajorVersion 5 / NtMinorVersion 1, NTBuildLab 2600.xpsp
- `windows.psscan` → 16 processes incl. `explorer.exe` (PID 1484) and `reader_sl.exe` (PID 1640, PPID 1484)
