DeepSec 2013 Talk: Psychology of Security – a Research Programme

René Pfeiffer/ October 23, 2013/ Conference

Have you ever considered the impact of the human mind on information security? Since our brain also deals with information,it should be an integral part of defence. Let’s take a look at psychology:  At DeepSec 2013 Stefan Schumacher will give you an introduction into the psychology of security and why we need to improve scientific research in this particular field. Most research about security is done in Computer Science, Electrical Engineering and Mathematics and is about technology, algorithms and computability. However, all security issues can be traced back to human behaviour. Be it Social Engineering, the choice of weak passwords, users leaving the password on a note-it attached to the TFT, admins using MD5 as a password hash or developers ignoring testing regulations. Humans are making decisions, not computers. Therefore, security is defined by

DeepSec 2013 Workshop: Hands On Exploit Development (Part 2)

René Pfeiffer/ October 21, 2013/ Conference, Stories

Unless you buy ready-made exploits or do security research (you know, the tedious task of testing systems and code, findings bugs and assessing their impact) you may wonder where they come from. To show you how to exploit a vulnerability and how to get to an exploit, we have asked Georgia Weidman for an example. She will be conducting the Hands On Exploit Development training. Early in my infosec education I took a class with a lab portion systems with known vulnerabilities. One system that I had difficulty exploiting was a Windows 7 host with HP Power Manager 4.2.6 which is subject to CVE-2009-2685. There is no Metasploit Module for this issue, but I was able to find some public exploit code on Exploit-db. The exploit calls out explicitly that it has been tested

DeepSec 2013 Workshop: Hands On Exploit Development (Part 1)

René Pfeiffer/ October 20, 2013/ Conference, Training

Software bugs evolve, just like their animal counterparts. Lesser bugs impact usability or are simple malfunctions. Once a bug impacts the security it is called a vulnerability. This means that something major is broken and that the internal logic can be manipulated to produce undesirable effects. Vulnerabilities can be exploited to create deterministic effects such as bypassing security checks, elevating privileges or other things. Exploits are the biggest bugs around. They have to work every time (at least with the software version affected by the bug/vulnerability), they need to insert specific code with a given purpose, and they should not compromise the functionality of the software (since you don’t want to be noticed) – So there is software development involved. Georgia Weidman will teach you how to get from a bug via a vulnerability

DeepSec 2013 Talk: Finux’s Historical Tour Of IDS Evasion, Insertions, and Other Oddities

René Pfeiffer/ October 19, 2013/ Conference, Security, Stories

The SANS Institute offers the article The History and Evolution of Intrusion Detection in its Reading Room. The article was published in 2001. It starts with the phrase „during the past five years…“. We now have 2013. Why is it important to examine the history of a technology which certainly is well established and widely deployed in information security? Well, first of all even to this day many people have a problem with what intrusion detection really is. Detecting an intrusion is not the same as intrusion detection. Secondly not everything marketed as intrusion detection system really detects intrusions. How can this be? The answer can be found by attending Arron „Finux“ Finnon‘s Historical Tour Of IDS Evasion, Insertions, and Other Oddities at DeepSec 2013. He will address the history of intrusion detection along the lines

DeepSec 2013 Talk: Pivoting In Amazon Clouds

René Pfeiffer/ October 17, 2013/ Conference, Internet

The „cloud“ infrastructure is a crucial part of information technology. Many companies take advantage of outsourced computing and storage resources. Due to many vendors offering a multitude of services, the term „cloud“ is often ill-defined and misunderstood. This is a problem if your IT security staff needs to inspect and configure your „cloud“ deployment with regards to security. Of course, virtualisation technology can be hardened, too. However the „cloud“ infrastructure brings its own features into the game. This is where things get interesting and where you have to broaden your horizon. Andres Riancho will show you in his talk Pivoting In Amazon Clouds what pitfalls you can expect when deploying code and data in the Amazon Cloud. Classical security tests won’t be enough. The Amazon Elastic Compute Cloud (EC2) is more than just virtual

DeepSec 2013 Talk: From Misconceptions To Failure – Security And Privacy In The US Cloud Computing FedRAMP Program

René Pfeiffer/ October 16, 2013/ Conference, Security

The „Cloud“ doesn’t stop when it comes to government data. Once government authorities play with outsourcing a lot more regulations need to be reviewed. Mikhail Utin talks about new results and a continuation of his last presentation at DeepSec conference: Our second presentation at DeepSec on so named “Cloud Computing” (CC) and associated services (CCS) considers practical implementation of the “concept” by US government in its FedRAMP program, which is expected to convert all the government IT services into “cloud” based ones. Our first (DeepSec 2012) presentation considered whether such “concept” is useful to protect privacy and implement such regulation as EU General Data Protection Regulation (GDPR) proposal. In fact, we have shown that CC is a misleading terminology, providing a confusing name to describe well-known IT infrastructure, which is little more than a

DeepSec 2013 Talk: The Economics Of False Positives

René Pfeiffer/ October 15, 2013/ Conference

Ever since networks got attacked the victims have thought of ways to detect and prevent attacks. Packet filters were the first idea. Closing a port meant to worry less about applications listening on them. So the trouble of protecting moved to the services that were still exposed. Filtering got more complex, protocols were inspected, signatures were introduced, intrusion detection systems were born. Great – but the attacks didn’t disappear. Instead you got alerts, a lot of them. Some were caused by real attacks, some were false alerts. Enter false positives. Setting off false alarms is a tried and true military tactic. After a couple of false alarms the sentries will probably be less alert. Translated to information security this means that alerts (and log files) will be ignored after a couple of false alerts.

DeepSec 2013 Workshop: Exploiting Web Applications Protected By $WAFs

René Pfeiffer/ October 11, 2013/ Conference, Security, Training

We all use web applications on a daily basis. Search engines, portals, web sites, blogs, information pages and various other content accessible by web browsers accompany us every day. This means that web server are the first exposed systems you will have to protect when deploying web applications. Usually you would add filters to your network that inspect access to the software and block any malicious requests. Packet filters were the tool of choice. Now we have application level firewalls to deal with content and protocols used. In the case of web applications the market has introduced a new kind of device: the web application firewall (WAF). In theory WAFs understand HTTP and know how a web browser talks to a web server. In practice no two web applications are alike, because they may

Changes to the DeepSec 2013 Schedule – two new Talks

René Pfeiffer/ October 10, 2013/ Administrivia, Conference

We had to change the schedule for the DeepSec 2013 conference slightly. Unfortunately two talks were cancelled, because the speakers could not confirm their presence. We are sorry to hear that, but every one of us know Real Life Interference™ can bust the best of plans. We have replaced the talk slots with submissions by other speakers. We will hear about Uncovering your trails – Privacy issues of Bluetooth Devices by Verónica Valeros & Garcia Sebastian. Bluetooth capabilities are pretty widespread and can be found in devices all over the world – and your workplace, of course. To quote Sheldon Cooper: „Everything is better with Bluetooth.“ And so is attacking devices and leaking information about users and devices. The second talk is pending a description and will be announced in short on our Twitter

DeepSec 2013 Talk: The Boomerang Effect – Using Session Puzzling To Attack Apps From The Backend

René Pfeiffer/ October 10, 2013/ Conference, Security

In past centuries attackers used battering rams to break down doors and siege artillery to blast holes into solid fortification walls. These were very tedious undertakings, so using alternate routes – possibly back-doors – were always highly regarded. Nowadays wonderful World of „Cyber“™ is no exception. The modern web-obsessed infrastructure has seen web browsers in local networks being compromised to access web-based back-end systems (through DNS rebinding attacks for example). Management consoles are a prime target, because once you gain access you probably can make the most out of elevated privileges. What about turning the back-end around and attack applications by it? Shay Chen has explored this attack vector and will present details in his talk at DeepSec 2013. Applications security mechanisms, secure software development processes, web application firewalls – collections of countermeasures that turn hacking

DeepSec 2013 Workshop: Attacks On GSM Networks

René Pfeiffer/ October 4, 2013/ Conference, Security, Training

Mobile phone networks have penetrated even the most remote areas of the Earth. You can send a tweet from Mount Everest if you like, the cell service is already there. In addition mobile phone networks feature 6 billion subscribers all over the world. Communication by mobile devices has entered the routine of daily life. It’s not all about talking. Smartphone, laptops, tablets and modems access the Internet by mobile phone networks. And as every security specialist knows: If there’s a network, then there are protocols, and these protocols can be attacked. True, it’s not as easy as TCP/IP since mobile phone networks feature sets of more complex protocols. Nevertheless these networks can be accessed, and you cannot block it. This is why you should get in touch with the threats to your organisation. DeepSec

DeepSec 2013 Keynote: Geopolitics and the Internet – the Meaning of “Hegemony”

René Pfeiffer/ October 3, 2013/ Conference, Discussion, Internet

Most of us think of the Internet as a place where the world virtually gathers and communicates without boundaries. It is regarded as a „virtual“ space where the confinement by borders of nation states is blurred by digital connectivity. People from all over the globe communicate with each other and form a truly cosmopolitan community. The trouble in paradise starts when countries switch off access to the Internet or prosecute whistle-blowers. Given the ever present notion of „cyber“ war we need to discuss geopolitics. It seems that the USA heavily dominates the Internet and regards it as its territory. Marcus Ranum will address the idea of hegemony and the USA with regards to the Internet in his keynote for the DeepSec 2013 conference: So, the topic is “the meaning of hegemony” – what does

DeepSec 2013 Workshop: Developing and Using Cybersecurity Threat Intelligence

René Pfeiffer/ September 26, 2013/ Conference, Security Intelligence, Training

The arsenal of components you can use for securing your organisation’s digital assets is vast. The market offers a sheer endless supply of application level gateways (formerly know as „firewalls“), network intrusion detection/prevention systems, anti-virus filters for any kind of platform (almost down to the refrigerator in the office), security tokens, biometrics, strong cryptography (just stay away from the fancy stuff), and all kinds of Big Data applications that can turn shoddy metrics into beautiful forecasts of Things to Come™ (possibly with a Magic Quadrant on top, think cherry). What could possibly go wrong? Well, it seems attackers still compromise systems, copy protected data, and get away with it. Security often doesn’t „add up“, i.e. you cannot improve your „security performance“ by buying fancy appliances/applications and piling them on top of each other. What

René Pfeiffer/ September 25, 2013/ Conference, Training

“If a tree falls in a forest and no one is around to hear it, does it make a sound?” You probably know this question. It’s a philosophical thought experiment questioning observation and knowledge of reality. There is a similar gedankenexperiment for information security: “If your organisation receives a spear phishing e-mail and no one is around to read it, does it create a security breach?” Communication is essential for everyone these days. If you run a business, you are forced to deal with communication on a daily basis. This didn’t start with the Internet. The telephone was first, and before there were letters and all kinds of ways to relay word from A to B. It’s a good idea to go back in time to avoid being distracted by technology but Trojan Horses
