Alien Technology in our Datacenters

Mika/ November 5, 2012/ High Entropy, Security, Stories

Sometimes when I watch administrators at work, especially when I start to ask questions, I get an uneasy feeling: “this is not right”. As it turns out many of the people who maintain, manage and configure IT or communication equipment don’t understand the technology they are using. At least not in depth. Mostly they have a rough idea what it’s all about but cannot explain in detail how it works and cannot predict what will happen if a few changes are made to the setup. Although I couldn’t put my finger on it I had a familiar feeling, something like a déjà-vu. Just recently when I browsed through my bookshelves it suddenly became clear: I reached for a science fiction classic, “Gateway” by Frederic Pohl which describes an alien race, the “Heechee”, which have

Talk about Data Loss Prevention

René Pfeiffer/ November 5, 2012/ Security

We will be presenting a talk about data loss prevention (DLP) on 9 November 2012 at the IT-Security Community Xchange 2012 (IT-SecX 2012) in St. Pölten, Lower Austria. DLP is a good example for measuring the security of your IT infrastructure. Keeping data in is as important as keeping attackers out these days. The tricky part is to know what data you have and where it lives. We will discuss how to approach DLP in terms of preparation, planning and implementation. In case you are in Austria you can meet us at the IT-SecX 2012. The event is organised by the University of Applied Sciences St. Pölten.

DeepSec 2012 Training: SAP Security In-Depth

René Pfeiffer/ November 2, 2012/ Security, Training

Your SAP installation is probably the most critical system in your company’s infrastructure. At the same time the informations accessed and processed by SAP systems origin from many sources. Securing infrastructure with this complexity is not an easy task, and testing your security measures requires a great deal of knowledge and training. In addition your will probably run web services talking to your SAP system – which is quite handy for attackers. In case you are short on knowledge about your own SAP deployment, there’s help. There will be an SAP security workshop at DeepSec 2012! The SAP Security In-Depth training will show you how to find out if your SAP infrastructure is secured. Knowing about segregation of duties and securing roles and profiles is fine in theory, but you have to make sure

DeepSec 2012 Talk: Wargames in the Fifth Domain

René Pfeiffer/ November 2, 2012/ Conference

We asked Karin Kosina to illustrate her talk Wargames in the Fifth Domain: “This is a pre-9/11 moment. The attackers are plotting.” These are the words of U.S. Secretary of Defense Leon Panetta addressing business executives on the dangers of cyberwar two weeks ago in New York. And just in case this did not leave the audience scared enough, Panetta also warned about the possibility of an upcoming “cyber-Pearl Harbor”. A massively destructive cyberwar, it seems, is imminent. Or is it? Is the world really on the brink of cyberwar? Time to panic and hide in our cyber shelters? – Well, I think things are slightly more complicated than that. Before you dismiss me as a peace-loving hippie who views the world through rose-tinted glasses: There is no doubt that our emerging information society

Zombies at the Hospital

René Pfeiffer/ October 31, 2012/ High Entropy, Security

It’s 31 October, so we have to talk about these zombies. You know them from the horror films. Dead, evil, and always hungry for brains (the latter also being true for any self-respecting HR department). Security researchers know a different kind of zombie. A zombie computer is a machine or device infected by a computer virus. It is considered compromised and contains additional features such as information retrieval, remote access or anything else you can put into code. Usually this is undesirable and fought with anti-virus software or (even better) strict security procedures. Now let’s combine the two types of zombies and add a spiffy virus outbreak into the mix. To go even further cinematic we use a hospital as the stage. Too unrealistic? On the contrary, hospitals do have a virus and zombie

DeepSec 2012 Talk: The „WOW Effect“

René Pfeiffer/ October 24, 2012/ Conference

If you have ever been in the position of analysing the remains of a compromised system, then you will probably know that a lot of forensic methods rely on data stored in file systems. Of course, you can always look at individual blocks, too, however sooner or later you will need the logical structure of the data. The question is: Do you rely on the file system to be honest with you? What happens if the file system (with a little help from the OS around it) tricks you into believing false information? The answer is easy. Your investigation will fail. Christian Wojner from CERT.at has a presentation for you which describes the stunning „WOW Effect“ stemming from Microsoft’s WoW64 technology. WoW64 is the abbreviation for Windows 32-bit on Windows 64-bit. It allows 64-bit

Groundhog Day (Not a Film Review)

Mika/ October 20, 2012/ High Entropy, Security

Recently there was a re-run of the movie “Groundhog Day” on German TV and after a while I felt a familiar feeling: Our security efforts are a lot like the story. The protagonist is caught in something like a time-loop until he gets everything right. A previously cynical, disrespecting, arrogant and selfish news reporter wakes up every morning to the same scene: The alarm clock switches to 6:00 in the morning, the radio plays “I got you babe” and the same day repeats over and over again. During the first iterations he doesn’t change his behavior, being quite a discomforting guy until he realizes that slight changes can make a big difference. He is only relieved from this situation after he gets everything right: Being nice to his former school schoolmate, changing the tires

DeepSec 2012 Keynote: We Came In Peace – They Don’t: Hackers vs. CyberWar

René Pfeiffer/ October 19, 2012/ Conference

„Cyberwar“ is all the fashion these days. Everyone knows about it, everyone has capabilities, everyone has a military doctrine to deal with it. Sceptics make fun of it, politicians use it for election campaigns, security researchers wonder what’s new about it, „experts“ use it to beef up their CV, cybercrime yawns, journalists invent new words, most others are confused or don’t care (probably both). This is why DeepSec 2012 features four talks about this topic, including the keynote by Felix ‘FX’ Lindner. FX explains what you can expect from his presentation: “The issues we are facing concerning the militarization and beginning arms race in the so-called “cyber domain” are not what you might think they are. I would like to highlight two aspects of how we, the civilian hackers, in my opinion handle things

DeepSec 2012 Talk: I’m the guy your CSO warned you about

René Pfeiffer/ October 15, 2012/ Conference

Social engineering has a bit of a soft touch. Mostly people think of it as “you can get into trouble by talking to strangers”, remember the “don’t talk to strangers” advice from their parents, dismiss all warnings and will get bitten by social security leaks anyway. You have to talk to people, right? You are aware that attackers will use social engineering to get past the expensive security hardware and software. Being aware is very different from being prepared. This is why we asked an expert of social engineering to give you an example of his skills. Be warned, it won’t get pretty and you won’t leave the presentation with the warm and cosy feeling that everything will be alright. To give you a sneak preview, here’s a digital letter from Gavin Ewan himself:

DeepSec 2012 Talk: Passive IPS Reconnaissance and Enumeration – false positive (ab)use

René Pfeiffer/ October 14, 2012/ Conference

Once you have a network, you will have intruders. You may already have been compromised. How do you know? Right, you use proper and hard to fool monitoring tools that will always detect good and evil. If you believe this statement, then you probably never heard of the dreaded false positive, commonly known as false alarm. Sometimes a search pattern triggers, but there is no attack. Getting rid of false positives is difficult. As a side effect security researchers have explored false positives as an attack vector. Arron ‘Finux’ Finnon is presenting a new look at intrusion detection/prevention systems (IDS/IPS) and new uses for false positives. You can use false positives to better understand the security posture from an attacker’s point of view, and more importantly be used to discover security devices such as

DeepSec 2012 Talk: Own the Network – Own the Data

René Pfeiffer/ October 12, 2012/ Conference

We all use networks every day. This is obvious when it comes to the Internet, but there are more networks if you use phones and other gadgets. Like it or not, these networks are a part of your infrastructure. Now you know, but attackers (and security people) knew this before. So, what can happen to your data if the network is compromised? The short answer: a lot! The long answer is given by Paul Coggin in his presentation at DeepSec 2012. Paul’s presentation discusses the security issues with the critical network architectures being deployed by service providers and utilities to support next generation network services such as IPTV, 3G/4G, smart grid, and more. There’s a lot happening behind the scenes. Once new products are announced, the stage has already been prepared. Network infrastructure security

DeepSec 2012 Workshop: Web Application Penetration Testing

René Pfeiffer/ October 11, 2012/ Conference, Training

If eyes are the window to your soul, then web applications are the gateways to your heart. Of course this is only a figure of speech, but once you take a look at security incidents and the role of web applications, then you get the idea of the analogy. Web applications are everywhere. It’s not always about your favorite intranet application. A lot of devices run web applications, too. And there are portals which really give you access to a whole variety of information and services. Speaking of services, you can have application programming interfaces (APIs), too. APIs usually do not talk to humans, but maybe they can be automated to do Bad Things™. This is where penetration testing comes in. Ari Elias-Bachrach will teach you how to approach web applications in the context

High Availability is not Redundancy

Mika/ October 11, 2012/ High Entropy, Odd

This is about the “A” in the CIA triad of security: Confidentiality, Integrity, Availability Just recently I was a witness of an incident where the failure of a perceived redundant system caused an outage of more than 5 hours of the central IT services of a multinational/intercontinental enterprise. Vital services like VoIP calls and conference bridges (which were interrupted with high profile customers) , SAP, e-mail, central file services, CAD, order processing, printing of delivery notes and therefore loading of trucks, processing of EDIFACT-based orders and invoices, etc. were unavailable for most of the 20.000 employees and customers worldwide during this black-out. What happened? Some when in the morning we noticed a lot of commotion in the department (open plan office) and quite soon it was obvious that all network based services were out

DeepSec 2012 Talk: The Interim Years of Cyberspace – Security in a Domain of Warfare

René Pfeiffer/ October 6, 2012/ Conference

In case you haven’t heard about it yet, officially that is, welcome to the fifth domain! As with space and other environments, the networked world has been discovered by various forces and groups for their advantage. The past years have shown that whatever happens in Cyberspace, doesn’t always stay in Cyberspace. It’s not always about the DDoS attacks, which have been blown out of proportion, but it’s about malicious software, reconnaissance, information extraction and other aspects which are less spectacular (watching less television helps to restore the perspective to normal). We’d like to set your perspective right and recommend listening to Robert M. Lee’s presentation about the Interim Years of Cyberspace. His talk focuses on the bigger picture in an effort to add a different view to the discussions taking place at DeepSec. The

DeepSec 2012 Talk: Evolution of E-Money

René Pfeiffer/ October 5, 2012/ Conference

The concept of electronic money has been around long before BitCoin entered the stage. The main characteristic is its electronic storage and exchange. This is both convenient and dangerous since digital goods can be stolen by copying data or cracking codes, depending on the design of the e-money system (which often will involve cryptographers). Jon Matonis will give you an overview about both the goals and the scary aspects of the cashless society. While the talk will focus on BitCoin, which is a peer-to-peer crypto-currency, you will get a deeper insight into how electronic currencies work, what challenges existing designs have solved (or haven’t), and which opportunities the use of digital currencies poses in the future. The phenomenon is quite young, but it is popular, even among criminals who already robbed a BitCoin bank.
