Learn about new features, changes, and improvements to UpGuard: During a web shell attack, a cybercriminal injects a malicious file into a target web server's directory and then executes that file from their web browser. A web shell is a malicious script written in any of the popular web application languages - PHP, JSP, or ASP.

After this, a Local File Include (LFI) vulnerability is used to connect the web shell to a selected web application page.

Because of this, data breaches and ransomware injections rarely immediately follow a web shell attack.

It's much easier to address the vulnerabilities that facilitate web shell injection than it is to intercept web shell attacks.
