Sebastian Guerrero is a Senior Security Consultant at Bishop Fox, where his areas of expertise are mobile and web application penetration testing (static and dynamic), as well as network penetration testing and product security reviews.

Sebastian has demonstrated critical impact during client engagements. While performing application penetration testing on an acquisition for a major automobile manufacturer, he found numerous SQL injection issues in the company’s main portals, through which an attacker could gain total control over the DBMS, access sensitive information, and obtain remote code execution over the server. Over the course of the engagement, Sebastian also determined that the acquired company had experienced breaches that it was unaware of over the course of two to three years.

He has also presented at conferences such as Black Hat Asia, RSA, and RootedCON and sits on the bug bounty halls of fame for organizations such as Facebook, Google, Microsoft, Instagram, Mozilla, Adobe, Pinterest, and eBay.
