vexium-kitnpm
vexium-kit is a confirmed malicious npm package (MAL-2026-13963) that executes malicious code on install (malicious versions 2.0.2, 10.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vexium-kit (npm)
What this malware does
On require, index.js issues an HTTPS request to the hardcoded bare-IP endpoint https://31.97.137.157:45000/icons/116 and passes the response's credits field to new Function('require','module',...,'Promise', data.credits), executing operator-controlled JavaScript with require, process, and Buffer in scope. The remote-eval sink is named getPlugin, accompanied by an unused setDefaultModule decoy referencing font-awesome CDN paths, while the README advertises the package as a zero-dependency utility toolkit. Declared dependencies (@primno/dpapi, better-sqlite3, sqlite3, node-machine-id) match the toolkit shape used to decrypt Chromium DPAPI-protected cookies/passwords and read browser Login Data databases, indicating the operator-supplied payload's intended follow-on capability against the installer.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for vexium-kit (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging vexium-kit across your stack and pipelines.
If you installed it — respond
Remove vexium-kit from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If vexium-kit 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 vexium-kit 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.

Detect & block this
O3 blocks vexium-kit-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
