Package x402-prompt-injection-scan@0.1.4 (npm) was scanned with no a static rule matches and no traced behavioral findings. No install-time lifecycle execution, no outbound network to attacker-controlled destinations, no credential or environment harvesting, no silent relay of caller-supplied data, and no persistence or backdoor mechanisms were observed in the package contents.

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.
