Which versions of ledgerflow-deploy-utils are malicious?

The following npm versions of ledgerflow-deploy-utils are flagged malicious: 1.0.1, 1.0.3, 1.0.4, 1.0.5. Treat any of these as compromised.

How do I remediate ledgerflow-deploy-utils if I installed it?

ledgerflow-deploy-utils 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 ledgerflow-deploy-utils — how do I know if it already compromised me?

If ledgerflow-deploy-utils 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 ledgerflow-deploy-utils part of a known attack campaign?

Yes — ledgerflow-deploy-utils is associated with the IN-MAL-2026-007771, IN-MAL-2026-009346, IN-MAL-2026-009345, IN-MAL-2026-009552 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Advisory published Jun 29, 2026Updated Jul 9, 2026

ledgerflow-deploy-utils is a confirmed malicious npm package (MAL-2026-6591) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.3, 1.0.4…). 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 ledgerflow-deploy-utils

What this malware does

On npm install, the package's postinstall script queries the AWS instance metadata service (IMDSv1) at 169.254.169.254 for the attached IAM role and POSTs the result, along with an IMDS-reachability probe, over plain HTTP to a hardcoded bare IP (54.226.194.239:80/chain3). The published library surface (index.js) only exports two no-op console.log stubs named validate/deploy, with no real functionality — the entire effective behavior is the install-time reconnaissance against AWS-hosted installers and CI runners. The combination of a placeholder API, a generic deployment-utility name suggesting an internal/private package, and install-time recon to a hardcoded bare-IP C2 matches the dependency-confusion / internal-name-squat pattern targeting corporate build systems, where exposed IAM role names enable follow-on credential abuse against the installer's cloud environment.
