Mr.SIP is a tool developed to audit and simulate SIP-based attacks. Originally it was developed to be used in academic work to help developing novel SIP-based DDoS attacks and defense approaches and then as an idea to convert it to a fully functional SIP-based penetration testing tool, it has been redeveloped into the current version.
It was used in an academic journal paper titled “Novel SIP-based DDoS Attacks and Effective Defense Strategies” published in Computers & Security 63 (2016) 29-44 by Elsevier, Science
In the current state, Mr.SIP comprises four sub-modules named as SIP-NES, SIP-ENUM, SIP-DAS and SIP-ASP. Since it provides a modular structure to developers, more modules will continue be added by the authors and it is open to be contributed by the open-source developer community.
