@asyncapi/specs@6.8.2

index.js in @asyncapi/specs 6.11.2 contains a string-array-obfuscated payload (_0x-style decoder) that, whenever the module is required, spawns a detached node child process. The decoded logic fetches a file from the IPFS gateway URL https://ipfs.io/ipfs/Qmet4fhsAaWMBUxNDfREHwgiyDeSWy4YSYs9wiKUW5jGyf, writes it as sync.js under a platform-specific hidden directory (LOCALAPPDATA/NodeJS on Windows, ~/Library/Application Support/NodeJS on macOS, ~/.local/share/NodeJS on Linux), and executes it detached via node. The obfuscation hides the URL, target filename, and use of https, child_process, and fs APIs. A legitimate AsyncAPI JSON spec loader has no need for obfuscated code or remote code fetch-and-execute; the behavior is inconsistent with the package's advertised purpose and gives whoever controls the IPFS content full code execution on any machine that installs or loads this version. ## Source: ghsa-malware (5715faf8c80acf7c963aac8c332a2cffed06a23ca9663a2fdcb6fd11be4325e9) 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. ## Source: google-open-source-security (938ab70c817e26ed594a554747f21aa339e5a01f3daf999dead6c94fd2289490) This package was compromised by the Sha1-Hulud: The Second Coming NPM worm. The malicious payload steals tokens and credentials and publishes them to GitHub. The worm will propogate itself to NPM packages the user owns and establish persistence is a GitHub action. The package may also destroy the user's home directory.
