Every line in the hit log is, by construction, a detector hit, so each record is mapped to a DefectDojo Finding. Upload the `*.hitlog.jsonl` file (not `report.jsonl`). + +Tested against the garak 0.15.x hit-log schema (`garak/evaluators/base.py`). + +Things to note about the Garak parser: +- +- **Aggregation:** hits for the same probe, target (generator), and detector are aggregated into a single Finding, with `nb_occurences` reflecting the number of hits and the most severe rung retained. +- **Severity** is derived from the detector `score` (0.0-1.0) and adjusted by probe family. Active-attack / code-execution / jailbreak families (e.g. `promptinject`, `dan`, `malwaregen`, `xss`) are nudged up one rung; content/quality families (e.g. `continuation`, `misleading`, `toxicity`) are nudged down one rung. Note that many garak detectors are string/word-list matchers that emit a binary score of `1.0`, so most real hits land in the upper severity bands. +- **CWE** is mapped from the probe family as a starter mapping (refined over time): + - prompt-injection families (`promptinject`, `dan`, `latentinjection`, `goodside`) -> **CWE-1427** (Improper Neutralization of Input Used for LLM Prompting) + - `xss` -> **CWE-79** + - `leakreplay`, `divergence` -> **CWE-200** + - all other families -> **CWE-1426** (Improper Validation of Generative AI Output) +- A hit log with no detector hits yields no findings. Lines that are not hit records (anything without a `probe` field, such as run/config metadata) are ignored. + +JSON Lines Format: +- +The parser accepts a `.jsonl` hit log. Each line is one hit record with fields including `goal`, `prompt`, `output`, `triggers`, `score`, `probe`, `detector`, and `generator`. The `prompt` and `output` values are serialized garak conversation/message objects (nested dicts), from which the parser extracts the displayed text. + +### Sample Scan Data +Sample scan data for testing purposes can be found [here](https://github.com/DefectDojo/django-DefectDojo/tree/master/unittests/scans/garak). + +### Deduplication +The "Garak Scan" scan type uses the `hash_code` [deduplication algorithm](https://docs.defectdojo.com/en/working_with_findings/finding_deduplication/about_deduplication/) with the following fields: + +- title (the garak probe and its goal) +- severity +- component_name (the scanned model / generator) + +`description` is intentionally **excluded** from the hashcode: it holds the specific prompt and model output for the hit, which garak samples non-deterministically on each run.
