This report explains what backdoor attacks are, outlines their history, and details common types (software, hardware, cryptographic, and RAT-based) along with the typical stages of compromise from infiltration to persistence. It highlights risks such as data theft, remote control, and surveillance, and provides prevention guidance including robust network security, timely patching, endpoint protection, audits and penetration testing, and employee training, with examples of tools and controls that can reduce attack surface.
