# API Reference: Windows Event Log Artifact Extraction Agent
|
|
|
|
## Dependencies
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| evtx (python-evtx) | >=0.8 | Parse Windows EVTX binary log files into JSON records |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python scripts/agent.py \
|
|
--evtx-dir /cases/case-001/evtx/ \
|
|
--output-dir /cases/case-001/analysis/ \
|
|
--output evtx_report.json
|
|
|
|
# Or specify individual files:
|
|
python scripts/agent.py \
|
|
--evtx-files Security.evtx System.evtx \
|
|
--output-dir /cases/analysis/
|
|
```
|
|
|
|
## Functions
|
|
|
|
### `parse_evtx_file(evtx_path) -> list`
|
|
Parses a single EVTX file using PyEvtxParser. Returns list of dicts with event_id, timestamp, channel, computer, event_data.
|
|
|
|
### `filter_critical_events(records) -> dict`
|
|
Filters records to 15 critical Event IDs (4624, 4625, 4688, 4697, 1102, etc.) grouped by Event ID.
|
|
|
|
### `detect_lateral_movement(records) -> list`
|
|
Identifies network logons (Type 3) and RDP (Type 10) from non-local IPs. Flags pass-the-hash indicators (Type 9 + NTLM).
|
|
|
|
### `detect_privilege_escalation(records) -> list`
|
|
Detects special privilege assignment (4672), group membership changes (4728/4732/4756), and account creation (4720).
|
|
|
|
### `detect_suspicious_processes(records) -> list`
|
|
Matches 4688 process creation events against a list of known attack tools (mimikatz, psexec, rubeus, etc.).
|
|
|
|
### `detect_log_clearing(records) -> list`
|
|
Identifies audit log clearing events (Event ID 1102 and 104).
|
|
|
|
### `detect_persistence(records) -> list`
|
|
Detects service installations (4697/7045) and scheduled task creation (4698).
|
|
|
|
### `generate_summary(records, findings) -> dict`
|
|
Computes statistics: total records, top event IDs, alert counts per detection category.
|
|
|
|
### `export_timeline_csv(records, output_path)`
|
|
Exports critical events as a sorted CSV timeline with timestamp, event_id, description, details.
|
|
|
|
### `analyze_evtx(evtx_paths, output_dir) -> dict`
|
|
Orchestrates parsing of multiple EVTX files and runs all detection functions.
