Warsitting

WiFi access points are growing like mushrooms after the rain. Every day, there are more and most of them are protected with WEP, WPA or WPA2 security mechanisms, whereas some of them are open to the public (either on purpose or by accident).

Sometimes it would be interesting to know the exact location of certain access points. In general, we can achieve this by triangulation, but the process can be nontrivial and normally we need some sort of special equipment. However, there is an easier way to do this: enter Google Location Services. Not many people are aware of this service, even though it was integrated with Firefox quite some time ago. It enables us to send our geographical location (coordinates) to web sites we trust if they need it. Google Location Services calculates our location by considering signal strenghts to our nearby wireless networks. We can use this service to determine our geographical location, but we can also use it to locate wireless access points by sending a request to Google Location Services, which defines maximal signal strength to each access point.

Results of Digital Challenge DSI 2011

Together with the end of DSI 2011 conference, the Digital challenge DSI 2011 also came to an end. Many people were considering various tasks of the challenge, however only 32 of the bravest actually participated in the event and used their computers in creative ways. Some of those were present at the conference as well, whereas others competed remotely over the Internet. The challenge lasted for 3 days and ran smoothly. However, we quickly noted that the first tasks were too easy, since some participants were getting close to maximum number of points very quickly. This lead us to adding new, more difficult ones and in the end, there were 26 different tasks available to choose from. Solving all 26 tasks would award a participant with maximum of 4500 points. The tasks were divided in 5 categories (general, cryptography and stenography, information gathering, penetration, social engineering). The easiest one was solved by 31 participants while the hardest was solved only by two cryptography ninjas.

We want to congratulate to all the participants which showed their creativity and solved at least some of the tasks. The four highest ranked hackers which passed the magic 3.000 points limit will receive practical awards – products of our partner Gemalto.

Digital Challenge

Digitalni izzivDigital Challenge is a competition in the field of computer and information security. Currently, it is a side event at a conference. The purpose of the challenge is to provide an attractive infosec activity through various challenges which will encourage the visitors to be more creative in using of computers and information technologies. Also, we want the challenge to demonstrate various concepts of information security in a entertaining way.

The challenge consists of more and less difficult tasks, which can be solved in arbitrary order by using a specially designed web portal. Normally, the participants will not need any special tools – in most cases, a web browser will suffice; however in some cases special tools might be needed to access the competition servers in different ways. On the web portal and on the screens at the conference, it will be possible to observe the progress (number of solved tasks and the sum of points for each participant) of the hackers almost in real time. At the official ending ceremony, the most successful hackers will receive practical awards.

Viris at DSI 2011

Dnevi slovenske informatike 2011Viris will also appear this year at the annual, this year already 18th, conference with name Dnevi slovenske informatike (Days of Slovenian informatics). The conference will take place in congress center Grand hotel Bernardin in Portorož between 18th and 20th of April 2011.

Milan Gabor (Viris CEO) has been invited to speak as at the conference about information security and challenges that we are facing today. At the conference Viris is also preparing a competition for all visitors called Digital challenge. More about this challenge will be announced at the conference or later on this web page.

We invite you to join us in Portorož! All additional information about conference DSI 2011 can be found on the web address: http://www.dsi2011.si/
