Sending media can add a package-selected newsletter attribution, while video thumbnailing can execute shell syntax supplied through a path. - **Trigger:** Create a WhatsApp socket, send media without annotations, or generate a video thumbnail. - **Impact:** The user's WhatsApp account can follow or unfollow channels without consent; messages can carry injected attribution; crafted paths can run commands with the application user's privileges. - **Evidence paths:** lib/Socket/newsletter.js, lib/WABinary/jid-utils.js, lib/Socket/messages-send.js, lib/Utils/messages.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T08:10:45.485Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconsented account mutation, message metadata injection, and shell command construction. - **Attack narrative:** The normal socket construction chain reaches the newsletter socket, which decodes two embedded identifiers and follows them on a timer. It also polls subscriptions and unfollows selected channels, without a user action for either change. Separately, media generation inserts a fixed newsletter attribution when callers omit annotations. The thumbnail helper uses a shell command with an unquoted path, exposing the host application to command injection. - **Rationale:** This package contains concrete, unconsented mutations of a user's WhatsApp subscriptions and message content, plus a reachable shell-injection flaw. These behaviors are unrelated to ordinary messaging-library operation and warrant blocking. - **Files touched:** lib/Socket/newsletter.js, lib/Utils/messages.js, lib/Utils/messages-media.js - **Network endpoints:** s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Creating a WhatsApp socket automatically follows two hard-coded newsletter accounts after a delay., The package continuously changes the user's newsletter subscriptions by unfollowing a hard-coded blacklist., Media messages without annotations receive a hidden, hard-coded newsletter attribution., Video thumbnail generation interpolates a supplied path into a shell command, enabling command injection. - **Evidence against:** No credential harvesting or exfiltration to a non-WhatsApp endpoint was found., The preinstall hook only invokes a local Node version check; it does not establish the malicious runtime behavior. ## Public findings ### 1.
