dims-hydration-uinpm
dims-hydration-ui is a confirmed malicious npm package (MAL-2026-14416) 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 dims-hydration-ui (npm)
What this malware does
On any import 'dims-hydration-ui', index.mjs chmods 0755 and spawns a bundled Linux x86_64 ELF at dist/internal/calc.dat as a detached child, described in code comments as a 'native math accelerator' while the README advertises a dependency-free pure-JS day-math library with no native code and no postinstall. The ELF is a full remote-access implant: it opens an interactive /bin/sh command channel, provides SOCKS5 proxying and TCP port-forwarding, executes further ELFs and shellcode fetched from the hardcoded C2 217.60.77.63 via curl into /tmp and via memfd_create for in-memory execution, and installs a ~/.config/systemd/user/svc-update.service unit for boot persistence. Remote command handlers /ssh_keys, /creds, /dbfind, /env, /clipboard, /download, /dataextract, and a BIGEXTRACT uploader collect SSH keys, credentials, environment variables, and arbitrary files and POST them to the operator at /api/extract-receive. A SHA-256 'integrity check' in the JS wrapper pins the exact malicious binary hash, framed as a safety measure.
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dims-hydration-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 dims-hydration-ui across your stack and pipelines.
If you installed it — respond
dims-hydration-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.
Did it already run?
If dims-hydration-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.
How O3 protects you
O3 blocks dims-hydration-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.
