From c04ec0b9ea3675b7dc0e88ead31d624e0781115d Mon Sep 17 00:00:00 2001 From: n0mad1k Date: Fri, 10 Apr 2026 07:38:28 -0400 Subject: [PATCH] Add comprehensive test suites for 7 bigbrother modules Cover packet_capture (rotation/zstd/AES), credential_db (dedup/hashcat/bulk), ja3_spoofer (profiles/cipher mapping/randomization), responder_mgr (hash capture/dedup/conf gen), ntlm_relay (protocol inference/command building/ coordination), ids_tester (risk assessment/preflight/caplet), and bridge (setup/teardown/ebtables/watchdog). 187 tests total, all passing. --- tests/test_bridge.py | 309
