Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing this package silently modifies a third-party Baileys module. The replacement later obtains remote channel IDs and causes the user's authenticated WhatsApp client to follow them. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-21T10:37:02.211Z - **Finished:** 2026-09-21T10:38:13.134Z - **Download time:** 765 ms - **Static scan time:** 235 ms - **AI review time:** 69922 ms - **Total time:** 70923 ms The recorded confidence comes from the underlying analysis.

The replacement later obtains remote channel IDs and causes the user's authenticated WhatsApp client to follow them. - **Trigger:** A consumer imports the package entrypoint. - **Impact:** An attacker can make an authenticated WhatsApp client follow operator-selected channels and persist the altered dependency file. - **Evidence paths:** index.js, install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:38:13.134Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** index.js schedules the installer, which replaces Baileys's newsletter.js with code that fetches a remote list and calls the follow operation for every listed channel. - **Attack narrative:** A normal import triggers an installer without user action. It locates Baileys, replaces its newsletter implementation, and marks the modification in that dependency's node\_modules directory. The injected implementation downloads channel IDs from the publisher-controlled URL and follows them through the existing authenticated socket after a delay. This is a covert, remotely controlled alteration of a foreign dependency and misuse of the consumer's WhatsApp session. - **Rationale:** The package contains a concrete import-time backdoor that mutates a third-party dependency and remotely directs authenticated account actions. The absence of an npm lifecycle hook does not remove the automatic import-time attack path. - **Files touched:** index.js, install.js - **Network endpoints:** https://raw.githubusercontent.com/DGXeon13/strings/refs/heads/main/strings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main module automatically loads install.js one second after the package is imported., The injected replacement fetches channel identifiers from a package-controlled GitHub URL and follows each identifier through the authenticated WhatsApp socket., The import-time routine overwrites Baileys's newsletter.js and leaves a cache marker to avoid repeating the modification., The manifest identifies index.js as the package entrypoint; it has no declared npm lifecycle script, but the import-time trigger remains automatic. - **Evidence against:** No credential-file harvesting, shell execution, or direct secret-exfiltration sink was found in the inspected entrypoint and installer., The manifest contains no preinstall, install, or postinstall hook. ## Affected versions and remediation This report applies to @dreamguyxeon/libsignal-node@1.0.3. - Avoid installing @dreamguyxeon/libsignal-node@1.0.3. 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.
