Corroborative evidence keywords

zero-day vulnerability details, zero, day, vulnerability, details, security, operations, threat, data

Proximity: 300 characters

Should match

• zero-day vulnerability — Primary topic phrase match
• zero day — Case-insensitive topic phrase match
• proof of concept — Alternative topic phrase match
• responsible disclosure — Additional topic phrase match

Should not match

• unrelated generic text without domain phrases — No relevant topic phrases present
• placeholder value 12345 — Random text should not match topic-specific regex
• 0day vulnerability — Generic word pair from old broad template should not match

Known false positives

• Authentication-related terminology in software documentation, security training materials, or system architecture descriptions without actual credentials. Mitigation: Require proximity to credential-specific patterns (API keys, connection strings, tokens) rather than general security terminology.
• Code snippets and configuration examples containing credential-related keywords or placeholder values in developer documentation. Mitigation: Check for common placeholder patterns (example.com, localhost, 0000) and documentation file types to reduce false positives from technical writing.
