Which versions of log-rotate-testmetest are malicious?

The following npm versions of log-rotate-testmetest are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate log-rotate-testmetest if I installed it?

Remove log-rotate-testmetest 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.

I already installed log-rotate-testmetest — how do I know if it already compromised me?

If log-rotate-testmetest 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 log-rotate-testmetest part of a known attack campaign?

Yes — log-rotate-testmetest is associated with the IN-MAL-2026-021577 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 log-rotate-testmetest across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for log-rotate-testmetest (version 1.0.1).

What this malware does

The package ships a binding.gyp whose sources field uses GYP command-expansion (<!(env node index.js...)) with no native source files, causing npm's implicit node-gyp rebuild to execute index.js at install time. index.js is a Caesar+10 (ROT) obfuscated eval blob that, once decoded, AES-128-GCM-decrypts a hardcoded hex ciphertext and the sibling data.bin, brotli-decompresses the result, writes it to a mkdtemp'd temporary file, and spawns it under Bun (Bun.spawn([execPath,'run',tmp]) / spawn(getBunPath(),['run',tmp])). package.json declares bun as a runtime dependency, deliberately routing execution through an alternate runtime rather than Node. The executed payload is fully opaque and attacker-controlled. The combination of a no-source binding.gyp used solely as a lifecycle trigger, multi-layer obfuscation (ROT + AES-GCM + brotli), and alternate-runtime dispatch has no legitimate native-build justification.
