Description: Web Shell is a script that can be uploaded to a web server to enable remote access and control. This type of tool is commonly used in the field of cybersecurity, specifically in vulnerability analysis and penetration testing. Its main function is to allow an attacker to execute commands on the compromised server, which can lead to obtaining sensitive information, manipulating files, or even taking full control of the system. Web Shells are often written in programming languages such as PHP, Perl, or Python, and can be designed to hide their presence, making them difficult to detect by security systems. The ease of use and the ability to interact with the server’s operating system make these tools popular among ethical hackers and cybersecurity professionals looking to assess the security of a system. However, their misuse can result in serious legal and ethical consequences, as they can be used to carry out malicious and unauthorized activities.
