Although klondike had always had the curiosity inherent to hackers to take apart things to see how they worked and even fix them and learned how to use MS-DOS with 7 years so he could play Commander Queen on his father’s computer things looked as if he was just going to be a computer programmer. But, after spending a summer reading Bruce Schneier’s applied cryptography and taking part, after lots of persuasion by the organizers, on a CTF competition where he wrote his own tools things started escalating quickly.

Since then klondike has done things like participating in some CTFs, becoming a Gentoo Hardened developer, writing an Arduino bootloader able to cryptographically verify updates, contributed cryptographic code to the Haskell community, written a fast implementation of the TTH algorithm and championed the introduction of new standards in the ADC protocol.

Currently, klondike is trying to start his own consulting company.

Talk PaF || STFU

PaF (Patch and Fix) is a methodology focused on getting hands on towards a solution as oposed to RaD (Report and Discuss). I developed this approach when I was the CISO of a cryptocurrency exchange called Lescovex. This approach is common in certain free software projects and hacking communities. In this talk we will see how adopting such approach correctly can help us improve the security of our organizations by enabling those who can help us address the problem. Some of the side effects of PaF include: CISOs being seen as helpful contributors by people involved in development and system administration, auditors being seen as a valuable source of insight and development teams becoming better at handling security proactively and less inhibed at raising questions.
