The replacement causes the affected messaging client to follow a hard-coded newsletter without user consent. - **Trigger:** Importing @shadowmd/libsignal-node in a process where @whiskeysockets/baileys is available. - **Impact:** The package tampers with a separate dependency, performs an unconsented account action, persists a marker, and may terminate the host process. - **Evidence paths:** index.js, install.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-27T20:46:45.290Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-package source overwrite with an injected newsletter-follow action. - **Attack narrative:** When imported, the entry point schedules installNewsletterAutoFollow. That code finds a separate @whiskeysockets/baileys installation and replaces its newsletter implementation. The embedded replacement schedules a follow request for a fixed newsletter identifier after the victim application starts. The patch stores a marker in the foreign dependency and can exit the host process after changing it. - **Rationale:** This is concrete, unconsented runtime tampering with a foreign installed package that causes a messaging-account action. It is unrelated to the advertised libsignal functionality and is malicious. - **Files touched:** index.js, install.js, node\_modules/@whiskeysockets/baileys/lib/Socket/newsletter.js, node\_modules/@whiskeysockets/baileys/node\_modules/.cache ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing the package automatically invokes code that patches another installed package., The patch locates @whiskeysockets/baileys and overwrites its newsletter source file., The injected replacement silently follows a fixed newsletter after the affected application starts., The patch creates a cache marker and later terminates the host process. - **Evidence against:** package.json contains no npm lifecycle hook., No credential harvesting, environment-variable collection, or arbitrary external endpoint is present in the inspected source. ## Public findings ### 1.
