Which versions of color-convert-helper are malicious?

The following npm versions of color-convert-helper are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate color-convert-helper if I installed it?

color-convert-helper 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 color-convert-helper — how do I know if it already compromised me?

If color-convert-helper 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 color-convert-helper part of a known attack campaign?

Yes — color-convert-helper is associated with the IN-MAL-2026-010961 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 color-convert-helper across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for color-convert-helper (version 1.0.0).

Advisory published Jul 28, 2026Updated Jul 28, 2026

Immediate action

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

npm uninstall color-convert-helper

What this malware does

The package's postinstall.js runs automatically on npm install and executes a shell pipeline that collects host identity (hostname, whoami, id, sudo -l, uname), CI/GitHub Actions environment variables, network interface information, running processes, and environment variables filtered by KEY/TOKEN/SECRET/CREDENTIAL/NPM/AZURE/GCP/CLOUD, then queries cloud instance-metadata endpoints (AWS/Aliyun/GCP/Tencent at 169.254.169.254) to fetch IAM security credentials. The collected data is base64-encoded and curled to the hardcoded attacker-controlled OAST domain pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com. The script also performs DNS and HTTP probes against the internal hostname tst.woa.com and issues an SSRF forwarder request, reporting resolvability back to the same OAST domain. The advertised purpose of the package is color conversion; the actual behavior is credential and cloud-IAM harvesting plus internal-perimeter reconnaissance from every install host.
