MAL-2026-4427 Malicious code in @rocketreach/rr-components (npm)

On npm install, both preinstall and postinstall lifecycle hooks execute postinstall.js, which collects host identifiers (hostname, platform, arch, OS username, cwd, Node version) and the full sorted list of process.env key names, then POSTs the JSON payload to a hardcoded https://webhook.site/d81181e1-e40b-478f-a0b4-f18069f9f677 collector. The package name @rocketreach/rr-components at version 9999.0.0 together with the self-identifying proof: "dependency-confusion-poc" field in the payload is the canonical dependency-confusion shape: publishing a high-version package under a target organization's private scope to public npm so that any misconfigured internal build resolves it. Even environment variable NAMES (not values) leak CI secret-naming schemes useful for follow-on attacks. Fires automatically on install with no user interaction.

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.
