OSV Malicious Advisory

scanned 3h ago · by OpenSSF/OSV

OpenSSF/OSV advisory MAL-2025-190656 confirms this npm version as malicious. lib/utils/ErrorHandling.js contains an obfuscator.io string-array with a base64+decodeURIComponent decoder colocated with a top-level main() invocation reachable via the package's main entry (lib/index.js -> components/HandleError.js -> utils/ErrorHandling.js). On require of the package, main() spawns a detached, stdio-ignored Node subprocess via `spawn('node', ['-e', <decoded-payload>], { detached: true, stdio:...

Summary
Malicious code in @asyncapi/generator-components (npm)
Details
lib/utils/ErrorHandling.js contains an obfuscator.io string-array with a base64+decodeURIComponent decoder colocated with a top-level main() invocation reachable via the package's main entry (lib/index.js -> components/HandleError.js -> utils/ErrorHandling.js). On require of the package, main() spawns a detached, stdio-ignored Node subprocess via `spawn('node', ['-e', <decoded-payload>], { detached: true, stdio: [...], windowsHide: true }).unref()`, where the '-e' argument is ~3 KB of code decoded at runtime from a base64 blob in the obfuscated string array. The payload delivery mechanism (heavy obfuscation, runtime string decoding, detached backgrounded child process, hidden window on Windows) is inconsistent with any documented error-handling functionality and matches the shape of a hidden load-time RCE injection into a legitimate AsyncAPI package. ## Source: ghsa-malware (f8979c7e0c324a5176bad2972f76ef64aaea7afdbbe7f728586c94682bd0d1ad) 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 (f627fc2ccd3242571f3bc5f3872bef674cde6c2539401724b25294592da5c2a9) 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.
