# API Reference: Memory Dump Credential Extraction Agent
|
|
|
|
## Dependencies
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| volatility3 | >=2.0 | Memory forensics framework (invoked via subprocess) |
|
|
| pypykatz | >=0.6 | Python Mimikatz for LSASS credential extraction |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python scripts/agent.py \
|
|
--dump /cases/case-001/memory.raw \
|
|
--output-dir /cases/case-001/analysis/ \
|
|
--output credential_report.json
|
|
```
|
|
|
|
## Functions
|
|
|
|
### `verify_dump(dump_path) -> dict`
|
|
Checks file existence, computes size and SHA-256 of first 1MB for integrity.
|
|
|
|
### `run_vol3(dump_path, plugin, extra_args) -> str`
|
|
Executes a volatility3 plugin via subprocess with 5-minute timeout. Returns stdout.
|
|
|
|
### `get_os_info(dump_path) -> dict`
|
|
Runs `windows.info` to identify OS version and build from the memory image.
|
|
|
|
### `find_lsass_pid(dump_path) -> int`
|
|
Runs `windows.pslist` and locates the LSASS process PID.
|
|
|
|
### `extract_hashdump(dump_path) -> list`
|
|
Runs `windows.hashdump` to extract SAM database NTLM hashes for local accounts.
|
|
|
|
### `extract_lsadump(dump_path) -> list`
|
|
Runs `windows.lsadump` to extract LSA secrets (service account passwords).
|
|
|
|
### `extract_cachedump(dump_path) -> list`
|
|
Runs `windows.cachedump` to extract DCC2 cached domain credential hashes.
|
|
|
|
### `run_pypykatz(dump_path, output_dir) -> dict`
|
|
Invokes pypykatz in JSON mode against LSASS minidump or full memory image.
|
|
|
|
### `parse_pypykatz_creds(pypykatz_data) -> list`
|
|
Parses pypykatz JSON output into structured credential list with NTLM, Kerberos, WDigest, DPAPI.
|
|
|
|
### `search_cloud_keys(dump_path) -> list`
|
|
Uses `windows.strings` to find AWS keys, JWT tokens, and auth strings in memory.
|
|
|
|
### `generate_report(dump_path, output_dir) -> dict`
|
|
Orchestrates all extraction steps and compiles the final report with summary and actions.
|
