Malicious code in @biz44/id10-client (npm)
What this malware does
This package is part of a malicious npm campaign published by the biz44 account. Importing the package automatically launches a detached JavaScript loader that retrieves and executes additional code from npoint.io. The retrieved payload communicates with an attacker-controlled server and implements clipboard collection, keyboard and mouse event collection, filesystem scanning, and theft of Chrome extension storage.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for @biz44/id10-client (version 1.1.11).
If you installed it — respond
Remove @biz44/id10-client 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 @biz44/id10-client 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.
