MAL-2026-11267 Malicious code in compose-logger-stand (npm)

[email protected] presents itself as a logger but its shipped code implements a credential-harvest and exfiltration pipeline. dist/secretScan/contentScanner.js and dist/secretScan/agentStartupAudit.js scan for secrets and POST results to huggingface.co endpoints (agentStartupAudit.js lines 490-563). dist/discord/discordRelayUpload.js (and its dist/-root duplicate) implements upload-via-Discord relay with base64-decoded payloads and repeated POST calls (lines 306/321/398), together with host reconnaissance primitives (ping). dist/relay/relayServer.js embeds a relay server with the same recon primitives. dist/core/deploymentDefaults.js and dist/hf/hfCredentials.js carry base64-encoded blobs holding embedded credentials/config used to authenticate to those services (scripts/encode-deployment.mjs is the author's own encoder utility for producing them). scripts/postinstall-agent.mjs is wired as a lifecycle agent that performs network I/O (GET, ping) at install time, so installing the package auto-executes the exfiltration/relay agent without any explicit user invocation. The combination — install-time agent + hardcoded third-party relay endpoints + shipped base64-obfuscated credentials + secret-scanning modules feeding those relays — is a credential-distribution / active-exfiltration package, not a logging library.

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.
