commonweb-balancenpm
commonweb-balance is a confirmed malicious npm package (MAL-2026-13439) that executes malicious code on install (malicious version 99.9.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in commonweb-balance (npm)
What this malware does
[email protected] is an empty shell package (empty index.js, no functionality) whose only effect on install is resolving its single declared runtime dependency ltidisafe from a direct tarball URL at https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.4.5.tgz rather than from the npm registry. On npm install, npm downloads and installs whatever bytes are served at that URL into the installer's node_modules, bringing that code into the dependency tree outside npm registry review. The GCS bucket is publisher-unrelated (no matching author or homepage metadata on the host package) and mutable — whoever controls the bucket can change the served tarball contents at any time without republishing to npm. The host package has no legitimate function other than to pull this out-of-registry dependency into installers, matching the dependency-chain dropper / lure pattern.

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 commonweb-balance (version 99.9.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging commonweb-balance across your stack and pipelines.
If you installed it — respond
Remove commonweb-balance 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 commonweb-balance 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 commonweb-balance 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.
