Malicious code in aws-crt-nodejs (npm)
What this malware does
The package aws-crt-nodejs was found to contain malicious code.
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 aws-crt-nodejs (all published versions).
If you installed it — respond
Remove aws-crt-nodejs 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 aws-crt-nodejs 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.

Detect & block this
O3 blocks aws-crt-nodejs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
