LPM AI assessed this version as clean; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 2.1.9 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-17377 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as clean; the assessments disagree. Independent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree. OpenSSF/OSV advisory MAL-2026-17377 confirms this npm version as malicious. This package is part of a large family (100+ identified as of September 2026) of near-identical forks of the Baileys WhatsApp Web library that inject a covert channel-subscription action into the WhatsApp socket layer... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-30T10:29:18.637Z - **Finished:** 2026-09-30T10:30:18.483Z - **Download time:** 511 ms - **Static scan time:** 7853 ms - **AI review time:** 51481 ms - **Total time:** 59846 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:** No confirmed malicious attack surface was established. The package exposes user-invoked media upload and conversion utilities, while its install hook only enforces a Node version. - **Trigger:** A consumer explicitly calls the media upload or conversion helpers; installation triggers the Node-version check. - **Impact:** A caller can intentionally upload supplied media to configured public hosts; no automatic collection or exfiltration path was found. - **Evidence paths:** package.json, engine-requirements.js, lib/Utils/messages-media.js, lib/Utils/generics.js, lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T10:30:18.483Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Caller-directed media upload and local thumbnail conversion. - **Rationale:** The lifecycle hook is limited to a Node-version gate, and the network, file, and process primitives are exposed as media-library utilities rather than automatically chained during installation or import. Source inspection found no concrete malicious behavior. - **Network endpoints:** https://catbox.moe/user/api.php, https://scdn.pdi.moe/upload, https://qu.ax/upload.php, https://uguu.se/upload.php, https://tmpfiles.org/api/v1/upload ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The exported upload helper sends a caller-provided buffer to public file-hosting services., Installation runs a Node-version check that can stop installs on Node versions below 20., Media thumbnail generation can invoke the locally installed ffmpeg executable. - **Evidence against:** The preinstall script only reads the Node version and exits when it is below 20; it does not download, execute, or modify files., The upload and network functions are callable library utilities, not invoked by the install hook or package import path., No self-dependency, credential harvesting, hidden payload execution, persistence, or broad project mutation was found. ## Affected versions and remediation This report applies to @saazkira/baileys@2.1.9. - Avoid installing @saazkira/baileys@2.1.9. 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.
