Since the beginning of November, I have joined KPMG Netherlands as a consultant. I work in Information Protection Services, doing what one would expect :). I love that all my colleagues live and breathe infosec just like me, and I look forward to contributing to better defended client systems!

[2015 May] IEEE S&P Symposium

posted Jun 5, 2015, 1:10 PM by Chris Mavrakis

(Miraculously) I was awarded the student travel grant by the IEEE Security & Privacy 2015 Symposium committee, to attend the conference at San Jose, California. 4-5 students are typically awarded and it was a great honor to be one of them. Great opportunity, thanks IEEE!

[2015 May] Various scripts

posted May 7, 2015, 8:10 AM by Chris Mavrakis   [ updated May 7, 2015, 8:10 AM ]

Occasionally, I write linux bash scripts to make my life easier. Here are some highlights:

  • bathealth - Shows live info and statistics about a Lenovo Thinkpad battery.
  • batsaver - Helps you prolong the service life of your Lenovo Thinkpad battery pack.
  • myvm - Easily start and stop VMWare services so that they do not drain laptop battery when VMs are not in use.
  • mfwifi - Helps the user easily configure a wireless interface statically. Very effective at solving connection problems at TU/e's Metaforum building. Eventually the university gave up on trying to solve the problems and shoved a few millions to retrofit ethernet plugs. This script effectively sovles the problem though :)
  • XSS Me strings - Default strings plus the ones in OWASP's XSS Filter Evasion Cheat Sheet, to be used with Firefox extension XSSme.

[2012 October] The ACRI Conference!

posted Dec 4, 2012, 7:46 AM by Chris Mavrakis   [ updated Dec 4, 2012, 7:50 AM ]

The experience from the previous conference helped me step up to this one. The 10th ACRI (Cellular Automata for Research and Industry) International Conference in Santorini was absolutely a success :)

I would like to thank the Conference Chairs for letting me help with registrations, payments, and some other (minor) organizing and programming stuff... Also, Santorini was amazing!

After more than a year of preparations, the 5th Panhellenic ECE Student Conference (SFHMMY 5 for short) was held in Xanthi, Greece.

More than 800 people joined the event and enjoyed two days (6th & 7th of April) of scientific paper presentations, invited speaker talks and a live music performance!
