Malicious code in @mikudeveloper/baileys (npm)

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (d03bf7166a5353a0b22409ebbb724ee53f24394c9ff340df668c970772796e28) This package is a fork of Baileys that declares `libsignal` in `package.json` as `github:tenka-san/libsignal-node` — a git dependency with no commit SHA, tag, or integrity check, resolving to whatever HEAD returns at install time and executing any lifecycle scripts inside it. The referenced GitHub account is unrelated to the upstream WhiskeySockets/libsignal-node maintainer, so its owner controls install-time code on every installer of this package. Separately, `makeNewsletterSocket` schedules a 120-second `setTimeout` after connection that fetches a channel-ID list from a hardcoded, mutable URL (`raw.githubusercontent.com/MikuDevReal/V2.0/refs/heads/main/pepek.json`) and issues `QueryIds.FOLLOW` on each entry using the installer's authenticated WhatsApp session, silently subscribing them to author-selected channels with no disclosure in the README. The remote list is author-mutable, so follow targets can change at any time. ## Source: ghsa-malware (ae1cbd433ff843bbf543121e434bdbc4cdfe37c00055a4709849f191c0f58fbb) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
