A backdoor is a hidden way into a computer, network, or device that bypasses normal security.
Hackers sometimes install backdoors using malware, allowing them to steal data or control the system secretly. Backdoors can also be built-in by developers for maintenance, but if left unsecured, criminals can abuse them.
Cyber cafés and businesses in Kenya face risks if their systems are not updated or protected with strong firewalls and antivirus software. Once a backdoor is open, attackers can use it to drain mobile money, spy on emails, or spread more malware.
