From 9cc203a87e516c7d7bff7ec0530eda0457641d46 Mon Sep 17 00:00:00 2001 From: cschantz Date: Wed, 5 Nov 2025 18:45:55 -0500 Subject: [PATCH] Add centralized IP reputation tracking system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Created a comprehensive IP reputation system that tracks IPs across all toolkit scripts with tags/attack types, scores, and detailed analytics. NEW FILES: - lib/ip-reputation.sh: Core reputation library with optimized database * Fast lookup using pipe-delimited file format * Attack type tagging system (bitmask: SQL, XSS, RCE, Bot, Scanner, etc.) * Reputation scoring (0-100) based on hits and attack severity * GeoIP country lookup integration * Automatic cleanup of old entries * Thread-safe with file locking - modules/security/ip-reputation-manager.sh: Interactive management tool * Query individual IPs with full details * View top malicious/active IPs * Database statistics and analytics * Manual IP flagging/whitelisting * Import IPs from logs * Export to readable reports * Live monitoring mode INTEGRATION: All security and analysis scripts now use the centralized reputation system: - modules/website/500-error-tracker.sh: * Tracks IPs generating 500 errors * Tags bots/scanners with BOT/SCANNER flags * Background processing for performance - modules/security/live-attack-monitor.sh: * Maps attack types to reputation flags * Tracks SSH bruteforce, SQL injection, XSS, DDoS, etc. * Real-time reputation updates - modules/website/website-error-analyzer.sh: * Tags filtered bots in error analysis * Builds IP reputation from website errors - launcher.sh: * Added IP Reputation Manager to Bot & Traffic Analysis menu * Menu option 4 in Security > Analysis > Bot & Traffic Analysis KEY FEATURES: ✓ Centralized IP tracking across ALL scripts ✓ Multi-tag system (IP can have multiple attack types) ✓ Reputation scores increase with more tags/attacks ✓ Country tracking via GeoIP ✓ Optimized for high-volume traffic (attacks with 1000s of IPs) ✓ Fast lookups even during DDoS ✓ Background processing doesn't slow down analysis ✓ Database cleanup/maintenance tools ✓ Export for reports and sharing BENEFITS: - Single source of truth for IP reputation - Scripts share intelligence (bot detected in one script = flagged for all) - Track IPs across time and multiple attack vectors - Identify repeat offenders with multiple attack types - Make blocking decisions based on comprehensive data - Performance optimized with file locking and background updates 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- launcher.sh | 18 +- lib/ip-reputation.sh | 459 +++++++++++++++++++++ modules/security/ip-reputation-manager.sh | 464 ++++++++++++++++++++++ modules/security/live-attack-monitor.sh | 16 + modules/website/500-error-tracker.sh | 15 +- modules/website/website-error-analyzer.sh | 6 + 6 files changed, 969 insertions(+), 9 deletions(-) create mode 100644 lib/ip-reputation.sh create mode 100755 modules/security/ip-reputation-manager.sh diff --git a/launcher.sh b/launcher.sh index cb829aa..60a99ed 100755 --- a/launcher.sh +++ b/launcher.sh @@ -222,10 +222,11 @@ show_bot_analysis_menu() { echo -e " ${CYAN}1)${NC} Full Bot Analysis - Complete scan (all logs)" echo -e " ${CYAN}2)${NC} Quick Scan (1 hour) - Recent activity only" echo -e " ${CYAN}3)${NC} Live Monitor - Real-time threat tracking" - echo -e " ${CYAN}4)${NC} IP Lookup & Investigation - Deep-dive on specific IP" - echo -e " ${CYAN}5)${NC} DDoS Pattern Detector - Identify DDoS attacks" - echo -e " ${CYAN}6)${NC} Traffic Pattern Analysis - Bandwidth & connection patterns" - echo -e " ${CYAN}7)${NC} User-Agent Analysis - Bot fingerprinting" + echo -e " ${CYAN}4)${NC} IP Reputation Manager - Query/manage IP database (NEW!)" + echo -e " ${CYAN}5)${NC} IP Lookup & Investigation - Deep-dive on specific IP" + echo -e " ${CYAN}6)${NC} DDoS Pattern Detector - Identify DDoS attacks" + echo -e " ${CYAN}7)${NC} Traffic Pattern Analysis - Bandwidth & connection patterns" + echo -e " ${CYAN}8)${NC} User-Agent Analysis - Bot fingerprinting" echo "" echo -e " ${RED}0)${NC} Back to Analysis Menu" echo "" @@ -983,15 +984,16 @@ handle_bot_analysis_menu() { 1) run_module "security" "bot-analyzer.sh" ;;
