If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.
