eslint-publish-releasenpm
eslint-publish-release is a confirmed malicious npm package (MAL-2026-13981) that steals credentials and exfiltrates sensitive data (malicious version 99.9.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in eslint-publish-release (npm)
What this malware does
[email protected] is a hollow package (index.js is an empty stub, no lifecycle scripts) whose only effect on install is dependency resolution. Its package.json declares its sole dependency ltidisafe as a direct HTTPS tarball URL pointing at a Google Cloud Storage bucket (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.6.4.tgz) rather than a version resolved from the npm registry. Installing this package causes npm to fetch and install arbitrary code from that bucket into the consumer's node_modules, where it becomes executable at require time by the parent project. The bucket is not a publisher-matched or npm-registry destination, the URL path contains the token depenconf (dependency-confusion), the package name resembles legitimate ESLint release tooling, and the 99.9.1 version number is characteristic of dependency-confusion lures. The package structure — empty main, no independent utility, sole purpose is pulling a tarball from an anonymous bucket — is a delivery-vector shape, not a real library.

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 eslint-publish-release (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 eslint-publish-release across your stack and pipelines.
If you installed it — respond
eslint-publish-release 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 eslint-publish-release 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 eslint-publish-release 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.
