Malicious code in 3layerdipstacksn9ze (npm)
What this malware does
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for 3layerdipstacksn9ze (all published versions).
If you installed it — respond
Remove 3layerdipstacksn9ze 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 3layerdipstacksn9ze 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.
