Malicious code in remove-bg-serverless-azure (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.0.1`

## Source: amazon-inspector (dcbce8344eb0762c4a9ef029743efe13045422b839444b828c245a09a85fc74e)
package.json declares `preinstall: node index.js`, so `npm install` automatically runs index.js. index.js reads os.hostname(), os.userInfo(), the user home directory, DNS server configuration, and the contents of /etc/passwd and /etc/hosts, and POSTs the collected data over HTTPS to the hardcoded host 7iqn7pls4ly6w8valba0xcxygpmha7yw.oastify.com (a Burp Collaborator / OAST subdomain used as an attacker-controlled callback). Installing the package causes installer-side identifiers and sensitive system files to be sent to an external attacker endpoint on install.
