Which versions of postgreesqlhelper are malicious?

The following npm versions of postgreesqlhelper are flagged malicious: 1.0.3. Treat any of these as compromised.

How do I remediate postgreesqlhelper if I installed it?

postgreesqlhelper is a typosquat — you almost certainly intended a legitimately-named package. Remove postgreesqlhelper, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

I already installed postgreesqlhelper — how do I know if it already compromised me?

If postgreesqlhelper was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is postgreesqlhelper part of a known attack campaign?

Yes — postgreesqlhelper is associated with the IN-MAL-2026-020034 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find postgreesqlhelper across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for postgreesqlhelper (version 1.0.3).

What this malware does

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.
