ledgerflow-deploy-utils@1.0.4

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.
