Malicious package

Malicious code in unifydata (npm)

MAL-2026-6441
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall unifydata

What this malware does

On require('unifydata'), index.js calls initPlugin() at module top level, performs an HTTPS GET to https://jsonkeeper.com/b/B40HL, JSON-parses the response, and executes the response's cookie field as JavaScript via new Function.constructor('require', body.cookie) — then immediately invokes the resulting function with the real require, granting it full Node module-loading capability. jsonkeeper.com is an anonymous, author-mutable JSON paste service; the bytes executed in any installer process are whatever the author has posted there at the time of import, with no pinning, hashing, or signature. The package presents itself with a header comment labeling it normalize-plus (ES6 safe version) and ships a benign-looking normalizePath helper as a decoy, while the published package name is unifydata — the mislabeled cover and unused utility code are consistent with a dropper masquerading as a routine helper. Any process that imports this package executes arbitrary attacker-controlled code with the privileges of that process.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for unifydata (version 3.6.6).

  2. If you installed it — respond

    Remove unifydata from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If unifydata 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.

Frequently asked questions

No. unifydata on npm has been identified as a malicious package (version 3.6.6 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks unifydata-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
