Individual skill
analyzing-indicators-of-compromise
Analyzes indicators of compromise (IOCs) including IP addresses, domains, file hashes, URLs, and email artifacts to determine maliciousness confidence, campaign attribution, and blocking priority. Use when triaging IOCs from phishing emails, security alerts, or external threat feeds; enriching raw IOCs with multi-source intelligence; or making block/monitor/whitelist decisions. Activates for requests involving VirusTotal, AbuseIPDB, MalwareBazaar, MISP, or IOC enrichment pipelines.

# Analyzing Indicators of Compromise
## When to Use
Use this skill when:
- A phishing email or alert generates IOCs (URLs, IP addresses, file hashes) requiring rapid triage
- Automated feeds deliver bulk IOCs that need confidence scoring before ingestion into blocking controls
- An incident investigation requires contextual enrichment of observed network artifacts
**Do not use** this skill in isolation for high-stakes blocking decisions — always combine automated enrichment with analyst judgment, especially for shared infrastructure (CDNs, cloud providers).
## Detection Gaps & Validation
- **Single-source blind spots:** VirusTotal aggregates AV opinions that lag zero-day and bespoke APT tooling -- a 0/70 score is not "benign." Require 3+ independent sources (VT + AbuseIPDB + MalwareBazaar/MISP + passive DNS) before a disposition.
- **Shared-infra false positives:** Cloudflare/AWS/Fastly CDN IPs and URL shorteners host both benign and malicious content; blocking the IP breaks thousands of sites. Pivot to the domain/URL, not the fronting IP.
