# ============================================================================= # lab7-iocs.txt # Lab 7 - Threat Intelligence Investigation # Runs on: WIN11 (192.168.1.40) - browser-based enrichment # (CDB list build in Part 3 is on WAZUH-SRV, 192.168.1.30) # ============================================================================= # This file contains a MIXED set of indicators of compromise (IOCs) presented # as if extracted from a recent investigation. Some are genuinely malicious; # some are benign false-positive traps a good analyst must clear. # # DO NOT assume any indicator is malicious. Enrich EVERY one against trusted # threat-intelligence services and reach a sourced verdict before acting. # # SAFETY: You will LOOK UP these indicators, not visit them. Never browse to a # suspected-malicious domain or download a suspected-malicious file to "check" # it. Enrichment services exist so you can assess without touching. # # Lines beginning with # are comments. One indicator per line. # ============================================================================= # ---- IPv4 ADDRESSES --------------------------------------------------------- # (enrich with AbuseIPDB; cross-check high-suspicion IPs against Talos / OTX) # # >>> INSTRUCTOR: replace the placeholders below with your chosen indicators # >>> before distributing. Verify each one's CURRENT enrichment result, as # >>> public reputation scores drift over time. # # EXAMPLE-IP-MALICIOUS-1 # planted known-bad (e.g., high-confidence AbuseIPDB scanner/abuse IP) # EXAMPLE-IP-BENIGN-CDN # benign trap (e.g., a major CDN / public DNS edge IP) # ---- DOMAINS ---------------------------------------------------------------- # (enrich with VirusTotal Domains tab and/or Cisco Talos) # # EXAMPLE-DOMAIN-MALICIOUS # planted known-bad (multi-engine / malware category) # EXAMPLE-DOMAIN-BENIGN # benign trap (top legitimate / trusted domain) # ---- FILE HASHES (SHA-256) -------------------------------------------------- # (enrich with VirusTotal Files - search by hash, NEVER upload a file) # # The EICAR test file is the SAFE, STABLE "known-bad" anchor: every antivirus # engine flags it, yet it is completely harmless. Its SHA-256 is fixed: 275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f # EICAR test file - Malicious (High), stable anchor # EXAMPLE-HASH-BENIGN # benign trap (SHA-256 of a known-clean OS binary; VT shows 0 detections) # ============================================================================= # WORKFLOW # 1. Sort these indicators by type into your SOC Engineering Notebook. # 2. Enrich each against the appropriate service(s). # 3. Record a verdict (Malicious / Suspicious / Benign) + confidence + source. # 4. Explicitly CLEAR the benign traps - state what evidence cleared them. # 5. Add ONLY High-confidence confirmed-malicious IPs to your Wazuh CDB list. # 6. Produce the IOC report and the CDB detection rule (Lab 7, Parts 3-4). # =============================================================================
