Detection Engine Updates Version 2.164

  Release Date: May 25, 2026

This release of the GitGuardian detection engine adds six new detectors — for Authentik API Token, Pagar.me Encryption Key, Adobe Refresh Token, LiteLLM API Key, brapi.dev API Key, and Open VSX Access Token — together with new checkers for Google OAuth2 Keys and a new analyzer for Adafruit IO API Key.

Notable precision improvements (measured on internal benchmarks):

• snyk_key: precision raised from ~40% to ~90%.
• finicity_authentication_keys: precision raised from ~67% to ~98%.
• hunter_api_key: precision raised from ~9% to ~100%.
• datadog_api_credentials: significant reduction in false positives.
• github_access_token: significant reduction in false positives.
• heroku_platform_key: significant reduction in false positives.
