Which versions of logutilkit are malicious?

The following PyPI versions of logutilkit are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate logutilkit if I installed it?

logutilkit is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

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

If logutilkit 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 logutilkit part of a known attack campaign?

Yes — logutilkit is associated with the 2026-03-license-utils-kit 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 logutilkit across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for logutilkit (version 1.0.1).

What this malware does

Malicious clone of a legitimate package. When using it, the code attempts to download and execute remote code. In on of the incarnations, the malicious code was embeded in the strongly obfuscated file, which at least collected data from cryptowallets and password managers and exfiltrated them to a hardcoded remote location.

The downloaded next stage varies depending on the running platform. On Windows, it's extream obfuscated script. On Linux and MacOS they are binaries, named "systemd-resolved" and "com.apple.systemevents" with clear signs of stealing browsers and cryptocurrency data.

Detect & block this

O3 blocks logutilkit-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
