Malicious package

hydration-vli-uinpm

hydration-vli-ui is a confirmed malicious npm package (MAL-2026-14535) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in hydration-vli-ui (npm)

MAL-2026-14535
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall hydration-vli-ui

What this malware does

The package's main entry (dist/index.mjs) locates dist/internal/math.mjs, chmods it to 0755, and spawns it as a detached child process every time the package is imported. The file is not JavaScript: its bytes begin with the ELF magic and it is a Linux x86_64 executable, renamed with an.mjs extension and framed in the README as a 'native math accelerator' referring to a nonexistent 'calc-cache.bin' file. Strings inside the ELF describe a full remote-access implant with a hardcoded C2 at 217.60.77.63, a 'SECURE_BEACON' protocol, and '/redshell' command handlers for socks/portfwd tunneling, arbitrary file drop-and-exec, shellcode injection, memfd_create-based in-memory execution, and systemd user-unit persistence (svc-update.service). Received commands are dispatched into /bin/sh and /bin/bash on the installer's host. The implant also exposes '/dataextract' and '/download' commands that POST arbitrary file contents via chunked HTTP to '/api/extract-receive' on the C2 host, along with '/ssh_keys', '/creds', '/dbfind', '/clipboard', and '/env' commands that harvest the installer's SSH keys, credential files, database contents, clipboard, and environment variables. Reachability requires only 'import "hydration-vli-ui"' — no user action, no authentication on the beacon channel — giving the C2 operator full remote shell control of any machine that installs and loads the package.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for hydration-vli-ui (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging hydration-vli-ui across your stack and pipelines.

  2. If you installed it — respond

    hydration-vli-ui is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If hydration-vli-ui was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks hydration-vli-ui before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. hydration-vli-ui on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
