Which versions of loadashjs are malicious?

The following npm versions of loadashjs are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate loadashjs if I installed it?

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

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

If loadashjs 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 loadashjs part of a known attack campaign?

Yes — loadashjs is associated with the IN-MAL-2026-018237 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 loadashjs across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for loadashjs (version 1.0.0).

What this malware does

loadashjs is a lodash typosquat whose index.js exports an empty object; the only functional code is scripts/postinstall.js, which runs automatically on npm install. The postinstall script POSTs a JSON body containing a platform label (derived in part from reading /proc/version and /proc/sys/kernel/osrelease to detect WSL) to a hardcoded bare-IP endpoint at http://193.70.34.101:20099/vote, then XOR-decodes an obfuscated URL with key 'stf2026' to https://github.com/bebraz1/aPzM50V1AKG2rVlH/releases/download/null/main.exe, downloads that PE binary to %TEMP%\main.exe and launches it detached with windowsHide. On WSL/virtualized Linux hosts, additional XOR-obfuscated byte arrays (BRIDGE_LAUNCHER_ENC, BRIDGE_SCRIPT_PRE_ENC, BRIDGE_SCRIPT_POST_ENC) are decoded and concatenated into a shell command passed to child_process.exec to invoke the same asset via a Windows-side bridge. The downloaded binary is unrelated to any advertised lodash-like functionality, is hosted under an unrelated personal GitHub account, and is fetched from an unpinned 'null' release tag.
