Two large hacker conferences have recently ended: BlackHat 2011 and DEFCON 19, which were held in Vegas.
At the DEFCON conference, in addition to reports, the most famous hacking (whitehat) Capture The Flag (CTF) competitions are held annually. DEFCON is a kind of alma mater of these competitions.

Competitions are held in two stages. The first, qualifying stage, in which all who wish can participate. Qualifiers are held in the format of “Own game” (or “Jeopardy” in English). Participants are provided with 25-30 tasks of varying complexity in such areas of information security as reverse engineering, forensic, binary exploitation, packet analysis, etc. In Russia, this type of competition is often called Task-based CTF.

The second, directly final, which goes 10-12 best teams. The final is held in the format of "combat" hacking. Each team is given an OS image on which several services are running. The team must defend their services and attack others. Each service keeps flags that must be stolen during an attack and, accordingly, protected during protection. Hence the name Capture The Flag.
This year, more than 700 teams registered for the qualifiers, with more than 280 completed with a non-zero score.
For the first time in the history of these competitions (and this is already the 19th conference in a row), the Russian team “IV” reached the final. The name is read as “four” or “four”, although foreigners “enviously call us” “ai vi”. The name appeared very simply, the team consists of 4 strongest teams of Russia in CTF: HackerDom, Leet More, SiBears, Smoked Chicken. No matter how ironic, but at the qualifiers, our team took 4th place and reached the final.

But we decided not to dwell on this and even though the US visa laws and half of the team were knocked down, in the final we won, guess which one? It is the 4th place, having overtaken many guards of this competition. Our team is ahead of such buffaloes as Shellphish from Santa Barbara University (iCTF competition is held annually), PPP from Carnegie Mellon University and Koreans PLUS from POSTECH-Pohang, as well as Japanese, Spanish and American security professionals.

PS
Well, it is well smoked, of course. It's Vegas, baby.
