Code that decodes and evaluates a base64 or hex-encoded payload at runtime is a strong indicator of intentionally hidden behaviour. Legitimate libraries do not need to obscure their execution logic.
HOW VIBECHECK DETECTS THIS
vibecheck clones your repository and runs Gitleaks, Semgrep, njsscan, and a suite of custom checks targeting patterns common in AI-generated code. This check is part of the Supply Chain category. When a matching pattern is found, Claude triages the finding and produces a plain-English explanation and a concrete fix — no security expertise required.
