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.

W007: Insecure credential handling detected in skill instructions
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
Insecure credential handling detected (high risk: 0.80). The prompt includes examples and prerequisites that show API keys and tokens embedded as literal strings in code and request headers (e.g., vt.Client("YOUR_VT_API_KEY"), headers{"Key":"YOUR_KEY"}), which encourages putting secret values verbatim into outputs/commands and thus creates an exfiltration risk.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 1.00). This skill explicitly queries public, community-driven threat intelligence services (e.g., VirusTotal, AbuseIPDB, MalwareBazaar, URLScan, Shodan) — see SKILL.md "Step 2: Multi-Source Enrichment" and scripts/agent.py functions like query_virustotal_hash, query_abuseipdb, and query_malwarebazaar — and directly uses those untrusted, user-submitted/third-party results to compute scores and dispositions (BLOCK/MONITOR), so external content could materially influence the agent's actions.
