Hello. My name is George Chatzisofroniou (@_sophron) and I work as a security engineer at CENSUS. My current interests
include cryptography, WiFi hacking, web security and network security.
This summer I gave a talk at BSides London. The talk was
called ‘Introducing wifiphisher, a tool for automated WiFi phishing
attacks’ and revolved around my recently published tool.
Wifiphisher is a security tool that mounts phishing attacks against WiFi
networks. I released it in early 2015 and since then it became quite
popular with a lot of press coverage. Community-driven BSides London
seemed to be the perfect choice for introducing the tool and clarifying
About two months ago (April 15th 2015) I visited Miami and presented at the
INFILTRATE Security Conference
a talk on Firefox heap exploitation, titled “OR’LYEH? The Shadow over Firefox”. The organization of the conference was flawless and the people I met there were amazing. A special thank you to the Immunity team for being great hosts and for their helpful feedback.
Hello, my name is Andrzej Dyjak and I’m part of the research team here at
A few weeks ago (on May 26th) I gave a talk titled “DTrace + OS X = Fun” at CONFidence 2015
in which I have described how DTrace can be used in order to ease various tasks
within the realm of dynamic analysis on the OS X platform.
The slides from this talk are now also available here.
CENSUS was one of the sponsors of the 5th InfoCom Security conference, that was held on April 1st, 2015 at the Divani Caravel hotel in Athens, Greece.
CENSUS will be sponsoring the 5th InfoCom Mobile World conference, that will be held on February 26th, 2015 at the Divani Caravel hotel in Athens, Greece.
CENSUS researcher Patroklos Argyroudis has recently presented a talk on heap exploitation abstraction at two conferences, namely
ZeroNights 2014 (Moscow, Russia) and
BalCCon 2014 (Novi Sad, Serbia). In the talk titled “Project Heapbleed”, Patroklos has collected the experience of exploiting allocators in various different target applications and platforms. He focused on practical, reusable heap attack primitives that aim to reduce the exploit development time and effort.
CENSUS researchers Alex Zacharis and Nikos Tsagkarakis presented their Point-of-Sale exploitation work entitled “PoS Attacking the Traveling Salesman” at this year’s DEFCON conference in Las Vegas, USA.
The talk illustrated vulnerabilities of airport point-of-sale systems that could
be used by adversaries to collect passenger data.
Material from this talk can be found here:
The presentation was a success and caught the attention of various technology blogs:
We would like to thank the organizers of DEFCON for hosting this great event and hope to meet
everyone again next year!
Here are the slides for our recent (albeit short) talk on “Secure Mobile App SDLC”, as presented at
the 4th Infocom Mobiles and Apps conference.
Census will be sponsoring the 4th InfoCom Mobiles and Apps conference, that will be held on February 12th, 2014 at the Divani Caravel hotel in Athens, Greece.
We are thrilled to be participating again, for the fourth time actually, at AthCon, the leading technical IT security conference in Greece. This year, our researchers Patroklos Argyroudis and Chariton Karamitas will be presenting novel exploitation techniques against the Mozilla Firefox browser.
