(Collaborative post by Gynvael Coldwind and Mateusz “j00ru” Jurczyk) Just yesterday another edition of the largest and most successful IT security conference held in Poland – CONFidence – ended. The Dragon Sector CTF team (which we founded and are running) actively participated in the organization of the event by hosting an onsite, individual CTF for […]

ZeroNights 2013 and NTVDM vulnerabilities

Just yesterday I had the pleasure to speak at a highly hacking-oriented Russian conference, ZeroNights, for the second time (see my “ZeroNights slides, Hack In The Box Magazine #9 and other news” post from last year). The conference itself has been great so far – several interesting and inspiring talks, lots of leet Russian hackers […]

Black Hat USA 2013, Bochspwn, slides and pointers

(Collaborative post by Mateusz “j00ru” Jurczyk and Gynvael Coldwind) Two weeks ago (we’re running late, sorry!) Gynvael and I had the pleasure to attend one of the largest, most technical and renowned conferences in existence – Black Hat 2013 in Las Vegas, USA. The event definitely stood up to our expectations – the city was purely […]

Approaching BlackHat US 2013 and new Dragon Sector blog

This is a quick reminder that Gynvael and I are going to attend BlackHat US 2013 in Las Vegas next week with the “Bochspwn: Identifying 0-days via System-Wide Memory Access Pattern Analysis” presentation on the second day of the event. The talk is going to largely extend our previous performance at SyScan this year (see […]

CONFidence 2013 and the x86 quirks

Another week, another conference. Just a few days ago, Gynvael and I  had the pleasure to attend and present at the CONFidence 2013 infosec conference traditionally held in Cracow, Poland. The event requires no further introduction – it has been simply the best Polish conference in the security area since it first started, and this […]

NoSuchCon’13 and crashing Windows with two instructions

The first edition of the NoSuchCon security conference held in Paris ended just a few days ago. Before anything else, I would like to thank all of the organizers (proudly listed at nosuchcon.org) for making the event such a blast! Both the location, venue and speaker line-up were amazing, with lots of free beer and […]

Fun facts: Windows kernel and guard pages

It has been a while since I last posted here, so I guess it’s high time to get back to work and share some more interesting Windows kernel internals goodies. Before we get to that, however, let’s start with a few announcements. First of all, there is a number of great infosec conferences coming up […]

ZeroNights slides, Hack In The Box Magazine #9 and other news

First of all, it has been reported to me that the system call list for Microsoft Windows Vista SP0 available at http://j00ru.vexillium.org/ntapi was wrong, containing syscall numbers for beta2 version of the system instead of the actual RTM Service Pack 0. The issue has already been resolved – apologies for any confusion this might have […]

Nullcon 2012 CTF

(Collaborative post by Mateusz “j00ru” Jurczyk, Gynvael Coldwind and Adam Iwaniuk) Friday, the 7th of September 2012 we were supposed to play the securitytraps.no-ip.org CTF. Unfortunately, the competition was postponed for a later date at the last moment, due to some significant technical problems. Next day evening we accidentally discovered another CTF taking place – […]
