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. The default socket builds a newsletter layer that, after two minutes, fetches a maintainer-controlled channel list and tries to follow those WhatsApp channels with the user's session. Errors are swallowed so the host app does not see the extra traffic. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-18T18:07:56.072Z - **Finished:** 2026-09-18T18:09:59.247Z - **Download time:** 1039 ms - **Static scan time:** 1404 ms - **AI review time:** 120732 ms - **Total time:** 123175 ms The recorded confidence comes from the underlying analysis.

Errors are swallowed so the host app does not see the extra traffic. - **Trigger:** Import or call the default makeWASocket entry and keep the process running for at least two minutes. - **Impact:** The logged-in WhatsApp account can be made to follow attacker-chosen channels without the app or user asking for that. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/username.js, lib/Socket/messages-send.js, lib/Socket/index.js, lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T18:09:59.247Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hidden delayed remote channel-follow loop - **Attack narrative:** An app that uses this Baileys fork creates the default WhatsApp socket. That path also builds the newsletter layer. Two minutes later a hidden timer downloads a JSON list of channel IDs from a GitHub repo the maintainer controls, then walks the list and tries to follow each channel with the user's logged-in session. Failures are ignored and follows are staggered, so the host app is unlikely to notice. The remote list can change after install, which lets the maintainer retarget which channels get followed. - **Rationale:** The default socket path includes a hidden delayed fetch of a maintainer-controlled channel list and an automatic follow loop against the user's WhatsApp session. That is unconsented account abuse, not ordinary newsletter helper APIs. - **Network endpoints:** https://raw.githubusercontent.com/MikuDevReal/V2.0/refs/heads/main/pepek.json ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Creating the default WhatsApp socket starts a hidden two-minute timer that downloads a remote JSON channel list from GitHub and tries to follow each ID on the user's session., Follow attempts swallow errors and wait 11 seconds between IDs, which hides the behavior from the host app., The newsletter layer is on the default makeWASocket import path, so ordinary socket use activates it., The GitHub file is maintainer-controlled and can change after publish, so the follow targets are not fixed in the package. - **Evidence against:** preinstall only checks that Node.js is 20 or newer and then exits., The follow call uses undefined Types\_1.QueryIds.FOLLOW, so the WhatsApp follow query may throw before it is sent., Scanner hits on protocol string tables, ffmpeg thumbnails, and a git libsignal dependency match a normal Baileys-style WhatsApp library. ## Affected versions and remediation This report applies to @mikudeveloper/baileys@1.0.0. - Avoid installing @mikudeveloper/baileys@1.0.0. 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.
