Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No specific harmful action is confirmed, but importing the package runs heavily obfuscated code that decrypts and executes hidden payloads. - **Trigger:** Importing the package through its index.js entrypoint. - **Impact:** The hidden code can perform local actions, but its concrete effects are unresolved from the inspected source. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T05:00:11.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint decodes an embedded program; that program decrypts AES-GCM payloads, evaluates code, and launches a child process. - **Rationale:** Importing the package triggers obfuscated code that decrypts and executes hidden payloads, creating a dangerous capability. The inspected source does not establish a specific attack behavior, so a warning is appropriate. - **Files touched:** index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The manifest points package imports to index.js and declares no lifecycle script., Importing index.js immediately evaluates code decoded from a large numeric array., Static decoding reveals AES-GCM payload decryption followed by dynamic evaluation and child-process launch; the encrypted payload's behavior remains unresolved. - **Evidence against:** The inspected source does not establish a specific network recipient, credential transfer, or destructive action., The manifest contains no install lifecycle hook. ## Affected versions and remediation This report applies to event-emitter-testmetest@1.0.6. - Avoid installing event-emitter-testmetest@1.0.6. 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.
