Excluding file types from a scan

This document is for:
Invicti Standard, Invicti Enterprise On-Premises, Invicti Enterprise On-Demand

Invicti ignores some URLs that do not need to be tested, using a list of excluded file types or extensions.

By default, Invicti ignores common file types such as image files (.jpg, .png, etc.) and video files (.mp4, .avi, etc.) as they are not typically a source of web application vulnerabilities. You can modify this list of excluded file types from the Extensions tab when configuring a Scan Policy.

Excluding Binary Files

Invicti can also detect binary files but, by default, does not test them. These files are outside the scope of scanning a web application for vulnerabilities. In fact, the Invicti scanners have a built-in mechanism to check if HTTP responses are binary responses; if they are, they will be excluded from tests.

If you have several binary files on your website, add their extension to this Extensions list, so that when Invicti identify them, it does not have to make the binary check. The advantage is that this shortens the scan duration.
