Open Source Penetration Testing Tools

Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster.

Resolver is a windows based tool which designed to preform a reverse DNS Lookup for a given IP address or for a range of IP’s in order to find its PTR. Updated to Version 1.0.3 added dns records brute force. Version 1.0.4 added stop button :)

DNScat is a "swiss-army knife" tool to tunnel traffic through DNS servers. It is a small, yet powerfull tool, similar to netcat. In conjunction with PPP server, it allows to build a VPN using DNS packets. DNScat is a useful tool for penetration testing.
