Which technique creates a shell within a website to gain remote access to server functionalities?

• A. Web Shell Detection
• B. Use of Web Shell
• C. Command and Control Server
• D. IoCs

Answer: (B)

Creating a shell inside a website is accomplished by using a web shell. A web shell is a script or small application uploaded to a web server that provides a browser-based interface to the server’s operating system. Through this web interface, an attacker can run commands, browse and manipulate files, and perform other administrative actions on the server remotely, effectively gaining control via the compromised website. This fits the scenario because the shell is delivered through the web server itself and used to access server functionalities from afar, often over HTTP(S). Attackers typically plant web shells by exploiting file upload flaws, misconfigurations, or vulnerable scripts, making the server execute commands as if they were operating locally. The other options aren’t about creating that backdoor. Web shell detection refers to finding such shells, not creating them. A command and control server is used to coordinate malware once it’s deployed, not to establish a shell on a web host. Indicators of compromise are clues used to detect breaches, not methods for gaining access.
