Which versions of lib-frontsga are malicious?

The following npm versions of lib-frontsga are flagged malicious: 9.999.999. Treat any of these as compromised.

How do I remediate lib-frontsga if I installed it?

lib-frontsga establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed lib-frontsga — how do I know if it already compromised me?

If lib-frontsga was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is lib-frontsga part of a known attack campaign?

Yes — lib-frontsga is associated with the IN-MAL-2026-016683, RLMA-2026-10751 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 lib-frontsga across my projects, lockfiles, and CI pipelines?

What this malware does

Package name 'lib-frontsga' published to the public npm registry at version 9.999.999 targets an internal package name via dependency-confusion resolution. A preinstall/postinstall lifecycle script (poc.js) runs on npm install and collects host identifiers (hostname, username, cwd, Node version) together with CI/build attribution (GITHUB_REPOSITORY, GITHUB_REPOSITORY_OWNER, GITHUB_ACTOR, GITHUB_RUN_ID, GITHUB_WORKFLOW, npm_config_registry, RUNNER_NAME, AWS_REGION, and Azure/Jenkins/GitLab identifiers). The collected data is transmitted to a hardcoded Interactsh callback subdomain via DNS queries and HTTP/HTTPS POST to votspfykpbaortacnitltze3m5k5swzg6.oast.fun. Any organization that internally uses this name without a scoped/internal registry pin will resolve this public copy and execute the install-time beacon, disclosing internal build-environment fingerprints to a third-party out-of-band server.
