RevOK

RevOK is a cybersecurity tool designed to simulate malicious targets for testing security scanners and software that processes attacker-controlled data. Its core feature, the "stub" component, allows users to listen for incoming requests and serve crafted attack responses based on customizable templates and substitution lists. Notably, RevOK has been utilized to identify critical vulnerabilities, including XSS to RCE bugs in Metasploit Pro, highlighting its effectiveness in researching and weaponizing security scanner vulnerabilities.
