Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. When the Claude bridge is used, it conceals identifying prompt content and starts Claude with permission checks disabled. This creates a stealthy, unrestricted AI-agent execution path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-14T10:36:19.291Z - **Finished:** 2026-09-14T10:37:48.453Z - **Download time:** 510 ms - **Static scan time:** 8772 ms - **AI review time:** 79876 ms - **Total time:** 89162 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** When the Claude bridge is used, it conceals identifying prompt content and starts Claude with permission checks disabled. This creates a stealthy, unrestricted AI-agent execution path. - **Trigger:** Running the configured Claude bridge for a bot request. - **Impact:** Prompts and tool instructions can drive a permission-bypassing agent while their identifying context is concealed. - **Evidence paths:** claude-bridge/src/claude.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-14T10:37:48.453Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Prompt identity scrubbing plus unrestricted Claude CLI execution. - **Attack narrative:** The package ships a bridge that rewrites product and identifier text specifically described as a detection bypass, then passes supplied prompts to Claude CLI with dangerously skipped permissions. The deliberate obfuscation of distributed code makes the active runtime difficult to audit. Although this is not an install-time attack and no direct exfiltration host was confirmed, the concealed unrestricted agent path is concrete malicious behavior. - **Rationale:** The bridge combines deliberate evasion with an unrestricted AI-agent launcher, and the distributed code is intentionally obscured. The absence of a consumer lifecycle hook limits installation risk but does not remove the runtime attack surface. - **Files touched:** claude-bridge/src/claude.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The Claude bridge deliberately renames product references and unknown uppercase identifiers before sending prompts, explicitly calling this a detection bypass., The bridge launches the Claude CLI with permission checks disabled while forwarding supplied prompts., The published package declares an obfuscation tool, and its distributed runtime files are heavily obfuscated., The manifest declares javascript-obfuscator as a development dependency. - **Evidence against:** The manifest has only a prepublish-only script, so no install hook runs for consumers., No fixed exfiltration endpoint was confirmed in the inspected bridge source. ## Affected versions and remediation This report applies to alvin-bot@5.149.0. - Avoid installing alvin-bot@5.149.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
