Which versions of lodahs-cli are malicious?

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

How do I remediate lodahs-cli if I installed it?

lodahs-cli establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed lodahs-cli — how do I know if it already compromised me?

If lodahs-cli 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 lodahs-cli part of a known attack campaign?

Yes — lodahs-cli is associated with the IN-MAL-2026-018252 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 lodahs-cli across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for lodahs-cli (version 1.0.0).

What this malware does

The postinstall lifecycle script in scripts/postinstall.js executes automatically on npm install and performs three attacker-benefiting actions. First, it POSTs a platform fingerprint as JSON to a hardcoded bare-IP endpoint at http://193.70.34.101:20099/vote (host assembled from a split array to hide the literal), acting as an install-time beacon. Second, it XOR-decodes (key 'stf2026') a hidden URL that resolves to https://github.com/beb1raz1/qPzM50V1AKG0rVlH/releases/download/null/main.exe — an unrelated personal GitHub account with an obfuscated repository name — downloads main.exe to %TEMP%, and spawns it detached. Third, when /proc/version indicates WSL, installAddonViaBridge() concatenates additional XOR-decoded segments into a shell command passed to child_process.exec with windowsHide:true, crossing the WSL boundary to fetch and execute the same.exe on the Windows host. The package name resembles a reversal of 'shadol'/'lodash' but the shipped code is a dropper rather than any CLI; there are no source files matching the advertised purpose.
