From 7ad1cc84656c28486c0f35145eda2b805178b685 Mon Sep 17 00:00:00 2001 From: tabledevil Date: Thu, 7 May 2026 19:20:19 +0200 Subject: [PATCH] Pin ubuntu:22.04, work around upstream rot, smoke test MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit APT-Hunter is unmaintained and breaks on modern dependency versions. Workarounds: - Pin ubuntu:22.04 (Python 3.10) — base for venv install. - Pin netaddr<1.0 — 1.x removed IPAddress.is_private(). - Add flatten_json (missing from upstream requirements.txt). - Patch EvtxDetection.py via sed: strip ' UTC' suffix from timestamps before parse() since dateutil rejects 'Z UTC' (Microsoft EVTX bug). start.sh: pre-mkdir the nested output/ dir APT-Hunter expects. test_smoke.sh: glob the actually-produced /output/apthunter_/output/ nested layout. Default SUBSET=DeepBlueCLI documented; YamatoSecurity is a working alternative and avoids the few corpora that hit other parser bugs. Validated end-to-end on amd64 Linux: 5/5 PASS on YamatoSecurity (16 EVTX), 1753 detections, 24K xlsx + 84K TimeSketch CSV produced.
