BUG #3 FIX: Whitelist check condition backwards (lines 2675, 2683)
- Changed: hits -eq 1 (repeat detection)
- To: hits -eq 0 (first detection)
- Impact: Whitelisted services now recognized on first detection, not 2nd+
- Prevents false alerts on initial detection of legitimate IPs
BUG #4 FIX: Scoring reset on repeat detections (line 2904)
- Changed: Reset score on hits==1 (repeat), ADD on repeat
- To: Initialize on hits==0 (first), ADD on repeat
- Impact: Repeat offenders now accumulate threat scores instead of resetting
- An IP detected 10 times now has higher score than first detection
BUG #5 FIX: Incorrect IP file format parsing (line 2851)
- Changed: grep -oP 'attacks=\K[^|]+' (looking for key=value)
- To: cut -d'|' -f4 (extract 4th field from pipe-delimited)
- Impact: Multi-vector attack detection now works properly
- Bonuses for IPs with both SYN + HTTP attacks now apply
BUG #1 FIX: Threat intelligence bonuses lost in background subshell (lines 2685-2749)
- Changed: Bonuses calculated in background subshell, written to temp file, lost
- To: Bonuses calculated synchronously, applied to $score variable
- Clustering detection remains backgrounded (for performance)
- Impact: AbuseIPDB reputation (+30 for 95%+ confidence, +15 for 50%+)
- Geolocation scoring now included in final threat assessment
- Added threat_intel_bonus to advanced intelligence bonuses section
TESTING:
- Syntax: ✓ bash -n validation passes
- Logic: ✓ Whitelist timing now correct
- Scoring: ✓ Repeat detections accumulate properly
- Parsing: ✓ Multi-vector detection functional
- Bonuses: ✓ Threat intel scores propagated
These 4 fixes address critical data loss and logic inversion bugs that were
preventing proper detection and scoring of repeat attackers and sophisticated
multi-vector attacks.
