Which versions of eslint-publish-release are malicious?

The following npm versions of eslint-publish-release are flagged malicious: 99.9.1. Treat any of these as compromised.

How do I remediate eslint-publish-release if I installed it?

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.

I already installed eslint-publish-release — how do I know if it already compromised me?

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.

Is eslint-publish-release part of a known attack campaign?

Yes — eslint-publish-release is associated with the IN-MAL-2026-017678, GHSA-rqq3-8xp4-pvcq 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 eslint-publish-release 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 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.

Malicious package

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.

Immediate action

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

npm uninstall eslint-publish-release

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.

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 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.
