Organizations recruit ethical hackers to replicate an actual cyberattack on their systems and networks. This attack consists of several phases, and it requires a ton of expertise and works for ethical hackers to discover all vulnerabilities and leverage them properly.
This hypothetical attack is designed to highlight all weak areas in the enterprise and attempt to address them. The five phases of ethical hacking are as follows:
1. Reconnaissance/Footprinting Reconnaissance is the first phase of ethical hacking, also known as the footprinting and information gathering phase. This is the preliminary phase where white hat hackers gather as much information as possible and implement security measures into the targeted system or network. The information gathered by white hat hackers usually is about three groups: network, host, and people. There are mainly two types of footprinting:
2. Scanning The scanning phase is the second step in an ethical hacker’s methodology. It entails applying all the knowledge learned during the reconnaissance phase to the target location to search for vulnerabilities. Hackers search for data such as user accounts, credentials, IP addresses, etc. There are three types of scanning, which include:

3. Gaining Access In this phase, the hacker creates the blueprint for the target’s network using the data gathered in Phases 1 and 2. Now the hacker has all of the information he requires. So he creates the network map and decides how to carry out the attack? There are various alternatives, such as:
The hacker obtains access to the network, programs, and system and then extends their access permissions to manage connected systems.
4. Maintaining Access When a hacker gains access, they choose to maintain it for future exploitation and attack. In addition, the hacker gains access to the organization’s Rootkits and Trojans and utilizes them to execute more network attacks. An ethical hacker attempts to keep access to the target until they have completed the activities or intend to complete in that target.
5. Clearing Tracks Once a hacker has obtained access, they leave no trace to prevent detection by the security team. They execute this by deleting cache and cookies, interfering with log files, and closing all open ports. This incorporates some of the steps an ethical hacker uses to cover and eliminate their footprint.
Ethical hackers use the following methods to hide their tracks in ethical hacking:
