Denial-of-Service (DoS) attacks aim to make a machine or network resource unavailable by flooding it with superfluous requests. When this is done from multiple compromised systems, it's called a Distributed Denial-of-Service (DDoS) attack. GitHub has become a central hub for open-source software, including a wide range of security tools. Among these are numerous "stress testers" or "doser" tools, which, when used without authorization, can be classified as DoS/DDoS tools.

By hosting code on GitHub, developers allow users to see exactly what the software is doing. This prevents the software from containing hidden malware or backdoors, which is common in "booter" software found on hacking forums.
