Extracting IOCs from Malware Samples

When to Use

• A malware analysis (static or dynamic) is complete and actionable indicators need to be extracted for defense teams
• Building blocklists for firewalls, proxies, and DNS sinkholes from analyzed samples
• Creating YARA rules, Snort/Suricata signatures, or SIEM detection content from malware artifacts
• Contributing to threat intelligence sharing platforms (MISP, OTX, ThreatConnect)
• Tracking malware campaigns by correlating IOCs across multiple samples

Do not use for IOCs from unverified sources without validation; false positives in blocklists can disrupt legitimate business operations.
