LWA-2026-5266 confirmed malware
testatesta@1.0.2
Malicious code in testatesta (npm)
T1195.002 · Compromise Software Supply Chain
Analysis
Package testatesta@1.0.2 declares itself as a dependency (circular/self-dependency), making it uninstallable. The package ships a trivial Express server scaffold with no repository, no README, and no legitimate project infrastructure. Its devDependency uses a naming pattern matching the publisher's prior known-malware campaign. The package appears to be a name-reservation stub — reserving the package name on the registry for a future typosquat or dependency confusion attack — rather than a functional module.
