BSidesLjubljana 2019 round 5

“Time really flies when you’re having fun”, they say. There was quite some activity and events related to cyber-security lately and based on the excitement that overwhelms us every time something new pops up, we could not disagree. BSidesLjubljana is in front of our doors again and since the tickets from every batch were gone in less than 15 minutes, we guess we are not alone out there. Talks are promising, there will be CTF again, so we’re looking for an exciting round 5. More information at https://0x7e3.bsidesljubljana.si/

ELK stack for Hackers

We can image a face of a person in a CFP review board that sees our paper submitted to a conference. “Oh no, another Wi-Fi talk”. But after reading it through one can see Wi-Fi from a different angle. We are presenting a way how to cross from terminal output of Wi-Fi packets to big data and visualization.



We are proud to share our knowledge in first Slovenian documentary film about hackers. Do they really exist in Slovenia? Who they are? What is their motivation?

The TV premiere will be on December 17, 2015 on channel TV SLO 2 at 8 PM.

Using CloudFlare and still leaking real IP address?

Recently I ran across interesting challenge. Some friends had problems with their service. Providing brand new service and having someone on the other side executing DDoS this service is not very promising beginning for some startup. Therefore, I decided to tackle this challenge and at the end it was not very hard to find leakage.

I know what you forgot last summer – DNS

After preparing and organizing some CTF events we discovered that players struggle at a particular task.  Often forgotten to look at it, but it is a must do in every penetration test. We are talking about a misconfigured DNS server that allows zone transfers from any source. This post is not about explaining details of a zone transfer, but rather about how to initiate one in Linux or Windows and if you want to learn more look DNS zone transfer. (more…)

BalCCon 2k15 CTF

Viris is proud to be the organizer of CTF (Capture the Flag) competition at BalCCon 2k15 security event that lasted from September 11th till 13th, 2015.  CTF competition was designed from pentester perspective where the ultimate goal was to take over BigFish’s Domain Controller. Besides real and legit hacking of the virtual environment, where flags were hidden in the form of security vulnerabilities, warm up tasks had been provided for challengers that didn’t want to get dirty.

Competition was heating up second day where we had couple of groups hacking as crazy. After two long nights there have been quite some challenges also for us as organizers, but we managed to solve them after all.

The grandmasters of CTF at BalCCon 2k15 are Hetti and cluosh. (more…)
