In the world of cybersecurity, it’s important to constantly be on the lookout for new threats. One way to do this is by keeping an eye on your organization’s external attack surface. Your external attack surface is the sum total of all the ways a hacker could potentially gain access to your systems—and it’s always changing. That’s why external attack surface management is so important. By monitoring your external attack surface and making sure it’s as secure as possible, you can help protect your organization from a wide range of cyber threats.
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.
