Which versions of zer0onedatetool are malicious?

The following npm versions of zer0onedatetool are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate zer0onedatetool if I installed it?

Remove zer0onedatetool 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is zer0onedatetool part of a known attack campaign?

Yes — zer0onedatetool is associated with the IN-MAL-2026-005327 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect zer0onedatetool in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking zer0onedatetool and packages like it before any post-install script runs.

What this malware does

The postinstall lifecycle script in this package issues curl POST requests to a subdomain of oastify.com — the out-of-band callback domain operated by Burp Collaborator / Project Discovery's interactsh. On every npm install, the script triggers an outbound HTTP request to an attacker-controlled OOB endpoint, which is the canonical fingerprint of a dependency-confusion / supply-chain reconnaissance payload (verifying the package landed in a victim environment and beaconing identifying host information out). The destination is not associated with any legitimate package functionality. Installer impact: any machine running npm install on this package automatically beacons to the attacker's OOB collector, leaking install-time host metadata and confirming code execution to the attacker.
