What this malware does
The package @emilgroup/discount-sdk-node was found to contain malicious code.
This package was compromised by the CanisterWorm campaign by the TeamPCP threat actor. The malicious payload establishes persistence as user systemd service and places a backdoor on the infected host. The malware will also harvest npm credentials and can autonomously spread.

Search your lockfiles and build artifacts for @emilgroup/discount-sdk-node (2 malicious versions).
If you installed it — respond
@emilgroup/discount-sdk-node is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If @emilgroup/discount-sdk-node 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.
