Which versions of kit-hydration-vim are malicious?

The following npm versions of kit-hydration-vim are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate kit-hydration-vim if I installed it?

kit-hydration-vim 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.

I already installed kit-hydration-vim — how do I know if it already compromised me?

If kit-hydration-vim 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.

Is kit-hydration-vim part of a known attack campaign?

Yes — kit-hydration-vim is associated with the GHSA-g9cm-v642-m5rj, IN-MAL-2026-017981 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find kit-hydration-vim across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for kit-hydration-vim (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 kit-hydration-vim across your stack and pipelines.

Malicious package

kit-hydration-vimnpm

kit-hydration-vim is a confirmed malicious npm package (MAL-2026-14086) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall kit-hydration-vim

What this malware does

On require/import, dist/index.mjs chmods 0755 and spawns the bundled ELF dist/internal/calc.dat as a detached child process. The binary is a full command-and-control implant that beacons to hardcoded C2 host 217.60.77.63 and accepts operator commands including /spawn (arbitrary process execution), /ssh_keys and /creds (harvest of the installer's SSH keys and credential files), /dbfind, /download, /dataextract (chunked file exfiltration via POST /api/extract-receive with BIGEXTRACT_START framing), SOCKS5 proxy, TCP port-forwarding, and remote ELF/shellcode fetch-and-exec. A /persist verb writes ~/.config/systemd/user/svc-update.service (Description 'System Update Service', ExecStart pointing at the implant, Restart=always) and enables it via systemctl --user for reboot persistence. The package advertises itself as a calendar/streak math library and frames the ELF as a 'native math accelerator' with an 'integrity verification' gate; none of the exported day-math functions actually invoke the binary, and daymath.mjs contains a comment stating the placeholder exists to make the math functions look dependent on the binary. The advertised purpose is a cover story for the dropper.

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.

Credential / info stealer

Find it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for kit-hydration-vim (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 kit-hydration-vim across your stack and pipelines.
If you installed it — respond
kit-hydration-vim 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.

Did it already run?
If kit-hydration-vim 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 kit-hydration-vim 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.
