Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (560c3d47344d4da5dffac230236b5248d2f1856c221ffac7ff72d4e3b197957b) Package zod-pino444@1.0.131 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. ## Source: ghsa-malware (1deba1d29d0eb3668c5ca30605d3bb8578f3427835bd947c263c67b8728456ca) 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.

Impact

Users installing affected versions of zod-pino444 risk having sensitive credentials and secrets harvested from their local filesystem and exfiltrated to attacker-controlled servers. This can lead to credential compromise, unauthorized access, and further downstream attacks leveraging stolen secrets. The malicious code executes automatically during installation without user interaction, increasing the risk of unnoticed compromise.

Defensive guidance

Users should immediately avoid installing or using zod-pino444 versions 1.0.128, 1.0.129, and 1.0.131. Remove these versions from any environments where they are present. Monitor for suspicious outbound network activity related to the described endpoints. Check the vendor or package repository for updates or advisories.

Summary

The zod-pino444 npm package versions 1.0.128, 1.0.129, and 1.0.131 include a malicious postinstall agent script that executes automatically during npm install. This agent performs host reconnaissance and scans the installer's filesystem for credentials and secrets. The harvested data is encoded in base64 and exfiltrated through HTTP POST requests to hardcoded remote endpoints, including Discord relay servers and huggingface.co URLs. The package contains multiple components supporting this attack, such as secret scanning modules, credential storage, configuration payloads, and a persistent relay server. This combination of automated execution, on-host secret scanning, obfuscated payloads, and outbound communication to attacker-controlled servers confirms an active credential theft operation embedded in the package.
