MAL-2026-18344 Malicious code in adyen-web-v6 (npm)

Package adyen-web-v6 version 0.0.0-stage contains two files and no detected install-time or import-time code that reads installer secrets, contacts external endpoints, drops or executes remote content, modifies the installer's filesystem outside its own directory, or opens a backdoor. The name resembles the Adyen web SDK family, but name resemblance alone is not a supply-chain threat and the shipped contents show no exfiltration, dropper, silent-relay, or persistence mechanism. The 0.0.0-stage version string and minimal file count are consistent with a placeholder or staging publication.

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.
