What is MAL-2026-12117?
MAL-2026-12117 is a malicious package in 1239i32049i, published on 5 Aug 2026.
Official description
Package declares a postinstall script that runs dist/index.js, the sole shipped file, which is heavily obfuscated with javascript-obfuscator (rotated string array, _0xNNNN identifiers, control-flow dispatch). At install time it reads process.env.P, issues an HTTPS GET to https://dropper-crm.vercel.app/api/payload/<P>, base64-decodes the response body, and executes it via new Function('require', decoded), granting the remote endpoint arbitrary code execution with require access on the installing machine. The package name is a numeric string with no documented functionality, no README, and no legitimate purpose beyond delivery of the remote payload.
What should I do about MAL-2026-12117?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
