What this malware does
According to the description, packages should demonstrate the dependency confusion attack. The realisation is, in fact, a spamming with packages having as the only purpose reporting basic data like hostname and current working directory.
Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for j5gnpfweguiwerbngpiutbgn0iutb0pfwef (version 0.0.1).
If you installed it — respond
Remove j5gnpfweguiwerbngpiutbgn0iutb0pfwef 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.
Did it already run?
If j5gnpfweguiwerbngpiutbgn0iutb0pfwef 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.
