What is MAL-2026-16150?
MAL-2026-16150 is a malicious package in postgreesqlhelper, published on 14 Sep 2026.
Official description
On require() of postgreesqlhelper, index.js decodes two base64 blobs shipped as parse.ts.map and init.ts.map, writes them to parsetmp.js and config.js, require()s parsetmp.js, and then unlinks the staged files. The decoded loader performs an HTTPS GET to https://www.jsonkeeper.com/b/V6NBX (a public paste host), AES-256-CBC decrypts the response with a hardcoded password and salt, and passes the plaintext to eval() at module load — arbitrary remote code execution against any process that imports the package. Payload naming as TypeScript sourcemap files, post-load deletion of the dropped and staged files, and package name/description that impersonate the get-proto package are consistent with deliberate concealment and typosquat lure.
What should I do about MAL-2026-16150?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
