Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package contains a concrete, obfuscated runtime path that silently modifies outbound message content with a fixed operator-branded newsletter annotation. No credential theft was found, but this hidden payload tampering warrants blocking. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-08-22T16:30:30.581Z - **Finished:** 2026-08-22T16:32:35.384Z - **Download time:** 510 ms - **Static scan time:** 10170 ms - **AI review time:** 114119 ms - **Total time:** 124803 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:** Importing the library loads an obfuscated message-construction module. Creating qualifying outbound media silently adds a fixed newsletter record to the message payload. - **Trigger:** Application imports the package and generates qualifying media messages. - **Impact:** Outbound user content is altered to carry undisclosed operator-controlled newsletter attribution. - **Evidence paths:** lib/Utils/messages.js, package.json, engine-requirements.js, lib/Utils/messages-media.js, lib/Utils/generics.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T16:32:35.384Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated branded newsletter metadata injection. - **Rationale:** The package contains a concrete, obfuscated runtime path that silently modifies outbound message content with a fixed operator-branded newsletter annotation. No credential theft was found, but this hidden payload tampering warrants blocking. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** lib/Utils/messages.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** Obfuscated runtime code creates a fixed newsletter annotation and injects it into qualifying outbound media., Brand identifiers and the integrity check are concealed behind an obfuscated string decoder. - **Evidence against:** The preinstall hook only enforces Node.js 20+ and has no network or file-mutation logic., Inspected code showed no credential/environment harvesting or AI-agent configuration writes., Observed network code is WhatsApp media/version functionality or caller-supplied media URLs. ## Affected versions and remediation This report applies to @lordmega/baileys@0.3.41. - Review the evidence and your use of @lordmega/baileys@0.3.41 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
