One of the primary steps in attacking an internet application is enumerating hidden directories and files. Doing so can often yield valuable information that makes it easier to execute a particular attack, leaving less room for errors and wasted time. There are many tools available to try to do this, but not all of them are created equally. Gobuster, a record scanner written in Go Language, is worth searching for. In popular directories, brute-force scanners like DirBuster and DIRB work just elegantly but can often be slow and responsive to errors. Gobuster may be a Go implementation of those tools and is obtainable in a convenient command-line format. The primary benefit Gobuster has over other directory scanners is speed. As a programming language, Go is understood to be fast. It also has excellent help for concurrency, so that Gobuster can benefit from multiple threads for quicker processing. The one defeat of Gobuster, though, is the lack of recursive directory exploration. For directories, quite one level deep, another scan is going to be needed, unfortunately. Often, this is not that big of a deal, and other scanners can intensify and fill in the gaps for Gobuster in this area.
