As a top ranked bug bounty researcher and Sr. Penetration Tester, I’ve discovered some critical vulnerabilities without ever directly accessing or scanning the target in question. These vulnerabilities are typically found by querying 3rd party services to discover cached and historic URL’s from a target and searching interesting URL’s. In some cases, this has lead me to discover critical “0day” vulnerabilities in commercial security products, Corporate owned websites and online services. In this blog post, I’ll discuss the methodology and step-by-step process used to find these vulnerabilities and how we can leverage tools like Sn1per Professional to assist us.
External Attack Surface Management (EASM) has become a crucial function for every organization to gain visibility of their perimeter security. Having the right tools and processes in place is vital to detecting new vulnerabilities before attackers do. In this blog post, we will outline the basic steps for discovering the attack surface with Sn1per Professional.
