MAL-2026-6795 Malicious code in zod-pino444 (npm)

Package [email protected] is a credential/secret harvester disguised behind a benign-sounding name. scripts/postinstall-agent.mjs is a lifecycle-triggered agent that runs on npm install and performs host reconnaissance (ping/GET, id enumeration). dist/discordRelayUpload.js is an exfiltration channel that POSTs collected data using base64-encoded payloads to remote endpoints (Discord relay pattern). dist/secretScan/contentScanner.js and dist/secretScan/agentStartupAudit.js implement a secret-scanning pipeline that harvests credentials from the installer's filesystem and transmits results to hardcoded huggingface.co endpoints via fetch(). dist/hfCredentials.js carries base64-encoded credential material used to authenticate the exfil channel. dist/deploymentDefaults.js and scripts/encode-deployment.mjs contain base64-encoded configuration/payload data used by the agent. dist/relayServer.js implements a persistent relay component. The combination of an auto-executed postinstall agent + on-host secret scanning + base64-obfuscated payloads + hardcoded outbound POST/fetch to attacker-controlled relay endpoints satisfies the active-attack fingerprint for installer-side credential theft.

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.
