Hardware Vendor-Induced Vulnerabilities

During a recent penetration test, a friend encountered some really strange findings that he asked me to review. Several of the desktops located in one of the departments had a process listening on an ephemeral, nonstandard TCP port.

DLP: An Important Tool In Protecting Data During Mergers & Acquisitions
