## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

date-fns-lite@1.0.10 presents as a lightweight date-formatting utility but ships a malicious postinstall.js that runs automatically on \`npm install\`. The script harvests installer-side secrets — AWS credentials (~/.aws), GCP application-default credentials, Azure tokens, kubeconfig, SSH private keys and authorized\_keys, /etc/shadow, and shell history — using /proc/1/root traversal to reach the host filesystem from inside a container. It also queries the AWS IMDS endpoint (http://169.254.169.254/latest/meta-data/iam/security-credentials/) and GCP metadata service for instance IAM credentials, probes the Docker socket via /proc/1/root/var/run/docker.sock to enumerate containers, and performs internal-network reconnaissance (default-gateway detection, /24 ping sweep, port probes on 22/80/443/3306/6379/9200/27017). The aggregated report is POSTed to a hardcoded bare-IP endpoint at http://115.190.124.243:9082/callback over plain HTTP. The package name mimics the widely-used \`date-fns\` library, and index.js contains a small plausible-looking date formatter as cover for the postinstall payload. Installing this package on any host — especially in CI or a container with host mounts — will disclose cloud credentials, SSH keys, and an internal-network map to the attacker.
