Alejandro Caceres (@DotSlashPunk) is a software developer, web application penetration tester, and security researcher. His main interest is in the nexus between distributed computing and network/application attacks. He is the founder of the PunkSPIDER project, presented at ShmooCon 2013, which is an open source project to fuzz the entire Internet’s web applications using a Hadoop cluster. He’s also the owner of Hyperion Gray, a software development company focused on open source projects in the area of distributed computing as it relates to security. He didn’t know how to work in shamelessly mentioning the DARPA Cyber Fast Track research project he is also working on (Web 3.0, also being presented at DEF CON 21), so he just wrote it in at the end of the bio. He is very classy.
