A hidden method of bypassing normal authentication to gain unauthorized access to a system. Attackers install backdoors after initial compromise to maintain persistent access even if the original vulnerability gets patched. Backdoors can be custom malware, modified system binaries, or planted credentials.
Finding and removing backdoors is a critical step in cybersecurity incident response. Incident responders must identify all persistence mechanisms during containment. Penetration testers demonstrate backdoor installation to show the real impact of a vulnerability. Threat intelligence analysts track backdoors associated with specific threat actor groups.
