In cybersecurity, a backdoor is a hidden and unauthorized access point in a computer system, application, or network that can be used to bypass normal authentication procedures and gain privileged access to the system or data.They are typically created by attackers who exploit vulnerabilities in software and hardware or even trick company staff into installing them by accident.Backdoors can: Bypass security controls Steal sensitive data Modify system configurations Launch attacks against other systems or networks And maintain persistent access to a compromised system, even if th

Portscanning is an important part of a penetration test, and you will hear about it a lot inside Cyber Security.Here’s how it works:Portscanning allows us to discover which ports are open, which are closed, and also which might be filtered or hidden behind a firewall.This is nothing too amazing on its own, but when we pair that with more complex tools such as Nmap, we can also discover what software or service is being run on those open ports.Why care about this?Because we can then use that information to later try and discover whether any known vulnerabilities exist for that software's partic
