Which versions of lodsh-cli are malicious?

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

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

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

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

Yes — lodsh-cli is associated with the IN-MAL-2026-018254 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 lodsh-cli across my projects, lockfiles, and CI pipelines?

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

What this malware does

lodsh-cli is a typosquat of lodash-cli. Its scripts/postinstall.js runs automatically on npm install and performs two hostile actions. First, it XOR-decodes a hardcoded URL (key 'stf2026') stored as an integer array, downloads a Windows executable to %TEMP%/main.exe (and on WSL runs a decoded PowerShell/cmd bridge command), and spawns the binary detached — arbitrary remote code execution on the installer's machine. Second, it POSTs platform information to a hardcoded bare IP 193.70.34.101:20099/vote, with the host assembled from a string-split array to hide the literal, serving as an install beacon and target selector. URLs, launcher commands, and script fragments are stored as XOR-encoded byte arrays and decoded at runtime to evade static inspection.
