DeepSec 2017 Talk: How To Hide Your Browser 0-days: Free Offense And Defense Tips Included – Zoltan Balazs

Sanna/ October 9, 2017/ Conference

There is a famous thought experiment described in the book A Treatise Concerning the Principles of Human Knowledge. It deals with the possibility of unperceived existence; for example does a falling tree in the forest make a sound when no one is around to hear it? Given the many reports and mentions about zero-day exploits, the question might be rephrased. Does a zero-day exploit cause any effects when no one is able to detect its presence? Before we completely get lost in philosophy, the question has a real background. Zoltan Balazs wants to address the issue of zero-days in his DeepSec 2017 presentation. The idea seems somewhat contrary to intuition – protecting exploits from being disclosed. Zero-day exploits targeting browsers are usually very short-lived. These zero-days are actively gathered and analyzed by security researchers.

DeepSec Video: Yes, Now YOU Can Patch That Vulnerability Too!

René Pfeiffer/ January 24, 2016/ Conference, Security

Once you got software, you most probably got yourself some decent bugs. Software vulnerabilities are everywhere. They come with the code. Managing patches and changes is they way of handling these weaknesses. At DeepSec 2015 Mitja Kolsek spoke about a new way of addressing vulnerabilities: „Software vulnerabilities are likely the biggest problem of information security, fuelling a rapidly growing market for “0days”, “1days” and exploits alike. It can be highly intellectually challenging to find a vulnerability and create an exploit for it, and super entertaining to reveal it all to the bug-hungry crowds (preferably along with a logo and a catchy name, courtesy of the marketing department). As a result, there’s been a lot of innovation and progress on the offensive side of information security, and a corresponding defensive industry is thriving providing quasi-solutions

DeepSec 2013 Talk: Auditing Virtual Appliances – An Untapped Source Of 0-days

René Pfeiffer/ November 4, 2013/ Conference, Security

System administrators and information security researcher often have to deal with appliances. Almost every organisation and company has a couple of magical black boxes sitting around. Usually they are connected to the network, and they do important stuff (such as filtering things, checking content, and the like). In the old days testing these appliances for their security record was hard. You had to open it, do a lot of tedious reverse engineering in order to understand how it works, and then conduct your tests to do your analysis. Fortunately the future is here, and so is a new form factor: virtual appliances! At DeepSec 2013 Stefan Viehböck of SEC Consult will talk about the advantages of having a virtual appliance to deconstruct. Virtual appliances aren’t very different from their embedded cousins, judged from the

DeepSec 2012 Workshop: The Exploit Laboratory – Advanced Edition

René Pfeiffer/ September 30, 2012/ Conference

Offensive security is a term often used in combination with defence, attack (obviously), understanding how systems fail and the ever popular „cyberwar“. Exploiting operating systems and applications is the best way to illustrate security weaknesses (it doesn’t matter if your opponents or pentesters illustrate this, you have a problem either way, and you should know about it). So where do exploits come from? Well, you can buy them, you can download them somewhere, or you can develop them. This is where The Exploit Laboratory comes in. Saumil Shah will teach you how exploits work – even on modern operating systems! Exploit Development is one of the hottest topics in offensive security these days. The Exploit Laboratory, in its sixth year, brings advanced topics in exploit development to Vienna this year. Arm yourself with skills

DeepSec 2012 Talk: Breaking SAP Portal

René Pfeiffer/ September 27, 2012/ Conference, Security

SAP products are very widespread in the corporate world. A lot of enterprises run SAP software for a whole variety of purposes. Since enterprises feature many levels of interconnection, there is also a great deal of exposing going on. Usually you do this by means of using portals. The term „portal“ is a trigger for penetration testers, because portals are the gateways to curiosity – and probably compromises. This may give an attacker access to systems that store all informations about your company and process all critical business transactions. You now have compelling reasons to attend DeepSec 2012 for we have a collection of SAP security talks and a workshop for you. Alexander Polyakov talks about how to attack SAP Portal. It is usually connected to the Internet. In turn the Internet is connected
