Summary
Malicious code in cdk-sagemaker-notebook-workflow (npm)
Details
The package declares a `preinstall` hook (`node index.js`) in package.json that fires automatically on `npm install`. The script collects `os.hostname()`, `os.userInfo().username`, `os.platform()`, current working directory, home directory, the contents of `/etc/passwd` (`fs.readFileSync('/etc/passwd', 'utf8')`), and the first 30 entries of `process.env` (`Object.entries(process.env).slice(0, 30)`), then POSTs the JSON payload to `https://3nrgzlqwix6erldow0s0kttsojuai36s.oastify.com/greengrass/<execId>` — a Burp Collaborator-style OAST host. Bulk env-var enumeration on CI runners typically captures `AWS_SECRET_ACCESS_KEY`, `GITHUB_TOKEN`, `NPM_TOKEN`, and similar credentials. The package name impersonates the AWS CDK construct namespace (`cdk-sagemaker-notebook-workflow`) and the README contains the string `Takeover By l0bo`, confirming attacker intent. This is an unambiguous install-time credential and host-data exfiltrator with a typosquat lure on the AWS CDK ecosystem.
