String Oriented Programming (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

The protection landscape is changing and exploits are getting more and more sophisticated. Exploit generation toolkits can be used to construct exploits for specific applications using well-defined algorithms. We present such an algorithm for leveraging format strings and introduce string oriented programming. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4817.en.html

Almighty DNA? (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

Die Erstellung von Personenprofilen aus DNA und ihre Speicherung in polizeilichen Datenbanken erfreut sich allgemeiner Akzeptanz. Die Annahme ist weitverbreitet, es ginge dabei allein um die Aufklärung von Mord und Totschlag. Tatsächlich speichert das Bundeskriminalamt hier aber Datensätze auf Vorrat und zwar aus immer geringfügigeren Anlässen und in immer größerer Zahl. Zudem werden die DNA-Datenbanken der europäischen Polizeien derzeit miteinander vernetzt. Das ist umso beunruhigender, als wir alle beständig DNA hinterlassen, ob nun in Haaren, Hautabrieb oder Speichel. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4913.en.html

"Neue Leichtigkeit" (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

Despite the vast new possibilities new medias offer to artists, musicians and composers, regulation authorities and governments are trimming creative minds in their freedom, introducing new laws, filters and limitations. On the example of "Europa: Neue Leichtigkeit" the immanence of unconditional artistic freedom in creativity is brought to the audience. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4832.en.html

Print Me If You Dare (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

Network printers are ubiquitous fixtures within the modern IT infrastructure. Residing within sensitive networks and lacking in security, these devices represent high-value targets that can theoretically be used not only to manipulate and exfiltrate the sensitive information such as network credentials and sensitive documents, but also as fully functional general-purpose bot-nodes which give attackers a stealthy, persistent foothold inside the victim network for further recognizance, exploitation and exfiltration. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4780.en.html

Implementation of MITM Attack on HDCP-Secured Links (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

A man-in-the-middle attack on HDCP-secured video links is demonstrated. The attack is implemented on an embedded Linux platform, with the help of a Spartan-6 FPGA, and is capable of operating real-time on HD video links. It utilizes the HDCP master key to derive the corresponding private keys of the video source and sink through observation and computation upon the exchanged public keys. The man-in-the-middle then genlocks its raster and cipher state to the incoming video stream, enabling it to do pixel by pixel swapping of encrypted data. Since the link does no CRC or hash verification of the data, one is able to forge video using this method. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4686.en.html

The movements against state-controlled Internet in Turkey (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

We are members of Alternatif Bilişim Derneği (Alternative Informatics Association)**, one of many organizations that oppose the ongoing efforts for state-controlled Internet in Turkey. We see that the problems with media control in Turkey and in Europe are increasingly becoming part of a global problem. The governments are working on their own view of a 'secure' Internet, and we have to articulate and suggest an alternative. In our talk we want to give an account of our anti-censorship movement and the challenges we face in Turkey. We will first provide an overview of the political events; sanctions, censorship regulations and attempts of resistance in the country. Then, we will point out the main problems we face in making use of laws and technology against state control. We would also like to use our presentation as an opportunity to meet people at the CCC with similar affinities and to learn from their experience. We see a great need to create global networks and communities to articulate an alternative message; the Internet as the peoples’ media. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4753.en.html

Don't scan, just ask (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

For years, we tried to identify vulnerable systems in company networks by getting all the companies netblocks / ip addresses and scanning them for vulnerable services. Then with the growing importance of web applications and of course search engines, a new way of identifying vulnerable systems was introduced: "Google hacking". However this approach of identifying and scanning companies ip addresses as well as doing some Google hacking for the (known) URLs of the company doesn't take all aspects into account and has some limitations. At first we just check the systems which are obvious, the ones that are in the companies netblocks, the IP addresses that were provided by the company and the URLs that are known or can be resolved using reverse DNS. However how about URLs and systems that aren't obvious? Systems maybe even the company in focus forgot? Second, the current techniques are pretty technical. They don't take the business view into account at any point. Therefore we developed a new technique as well as framework to identify companies’ web pages based on a scored keyword list. In other words: From zero to owning all of a company’s existing web pages, even the pages not hosted by the company itself, with just a scored keyword list as input. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4770.en.html

Antiforensik (28c3)

Fri, 30 Dec 2011 01:00:00 +0100

Antiforensik ist ein noch eher neues Thema und bekommt zunehmend mehr Bedeutung. IT-Forensik als Mittel zur Aufklärung von Sachverhalten kann vor Gericht aber auch in internen Ermittlungen maßgeblich für Freisprüche oder Schuldsprüche sorgen. Daher ist es besonders schlimm, wenn die dazu verwendeten Programme nicht korrekt arbeiten und sogar mit präparierten antiforensischen Aktionen angegriffen werden können. Der Vortrag zeigt eine bisher unbekannte und dennoch technisch einfache Sicherheitslücke in mindestens einer weltweit verwendeten Forensik-Suite und wie diese ausgenutzt werden kann: Hinzufügen von Ermittlungsergebnissen, Löschen/Verändern von Ermittlungsergebnissen, Infektion des Auswertesystems mit Malware. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4828.en.html

Eating in the Anthropocene (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

Over the last few years hackers have begun to take a larger interest in food, gastronomy and agriculture. For many in the community the ability to create DIY molecular gastronomy hardware and recipes is an obvious entry point. This talk extends some of these early investigations beyond the kitchen and the chemical properties of food by looking at specific cultivars, food technology organizations, and connections between food systems, ecosystems and planetary change. Part 1 of the talk explores some of the more bizarre and interesting biotechnologies and genomes that make up the human food system on planet earth, including Chinese Space Potatoes, Mutagenic Grapefruits and Glowing Sushi. Pat 2 of the talk presents ideas of food system redesign particularly relevant to hackers and food explorers: utopian cuisines, resilient biotechnologies and eaters as agents of selection. In Part 3 we provide access to resources and propose interesting projects for black hat food hackers, DIY BIO foodies, and prospective food security researchers, such as mining the IAEA's database of radiation breeding, eating things that weren't meant to be eaten and defending agricultural biodiversity. By introducing less known stories from the history of food and technology, and providing access to resources we hope to get more hackers curious about exploring, questioning and redesigning our human food systems. BIO: Zack Denfeld & Cathrine Kramer run the Center for Genomic Gastronomy an independent research institute that studies the genomes and biotechnologies that make up the human food systems on the planet. They are currently in residence at Art Science Bangalore and a curating a show on the future of food at the Science Gallery in Dublin Ireland. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4768.en.html

Does Hacktivism Matter? (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

Do you remember those days when hackers were “real men?” When hacking was not yet a crime and the cyberspace an undiscovered land? Just before anti-hacking laws were introduced in Germany? Back in these days, the famous founding father of the CCC made the Bundespost (Germany's Federal Mail Service) meet its Waterloo, when they hacked Bildschirmtext (Btx)—the epitome of both technological utopias and dystopias at that time. But soon, hackers suffered a setback: new laws criminalized hacking in the name of fighting white-collar crimes. Simultaneously to the laws, things were getting rougher in the media and the public opinion. While being seen as a weird vanguard of technology before, hackers soon became pranksters and outlaws. Apparently hacktivism, the portmanteau word for hacking activism, had failed to shape the policies in the dawning information society. However, there are evidences that hacktivism had an impact on the new computer crime legislation—not in terms of having more, but less restrictions implemented in the law. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4749.en.html

Crowdsourcing Genome Wide Association Studies (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

It was only a couple of years ago that generating genetic information about individuals was expensive and laborious work. Modern techniques have drastically cut cost and time needed to get an insight into one's genome and have ultimately led to the formation of personal genetics companies – like 23andMe, deCODEme and others – that now offer direct-to-customer genetic testing. With a price tag of those tests starting at about 100 €, the number of people that do such tests is on the rise. By now, 23andMe alone has over 100.000 paying customers, with over 60.000 of them willing to donate their genetic data and to actively participate in research projects by filling out surveys, e.g. on their medical histories. This has resulted in a high-quality dataset with genetic information of 60.000 individuals. The best part: The data has already been paid for by the participants in the research. Who would not love to get their hands on data like this? Unfortunately, the data sits locked away in corporate vaults, inaccessible to interested (citizen) scientists. But what if we could change this? We've created openSNP, a central, open source, free-to-use repository which lets customers of genotyping companies upload their genotyping data and annotate them with phenotypes. OpenSNP provides its users with the latest scientific research on their genotypes and lets scientists download annotated genotypes to make science more open. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4730.en.html

Demokratie auf Sächsisch (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

Alles begann im Vorfeld des 13. Februar 2010. Nachdem sich der sogenannte rechte Trauermarsch am Jahrestag der Bombardierung Dresdens innerhalb weniger Jahre zum größten Naziaufmarsch Europas entwickelt hatte, gründete sich 2009 ein bundesweites Bündnis aus Antifa-Gruppen, Parteien und Zivilgesellschaft mit dem Ziel, diesen zu blockieren. Soviel Engagement gegen Rechts war den sächsischen Behörden jedoch von Anfang ein Dorn im Auge, so dass die Oberstaatsanwaltschaft Dresden bereits im Januar 2009 den Vorwurf des „Aufrufs zu Straftaten“ konstruierte, um Räumlichkeiten des Bündnisses zu durchsuchen, Plakate zu beschlagnahmen und so die Mobilisierung nach Dresden zu unterbinden. Die Taktik ging nicht auf: Am 13. Februar 2010 belagerten mehr als 10.000 Menschen den Aufmarschort, woraufhin der Naziaufmarsch nicht stattfand.

Building a Distributed Satellite Ground Station Network - A Call To Arms (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

As proposed by Nick Farr et al at CCCamp11, we - the hacker community - are in desperate need for our own communication infrastructure. So here we are, answering the call for the Hacker Space Program with our proposal of a distributed satellite communications ground station network. An affordable way to bring satellite communications to a hackerspace near you. We're proposing a multi-step approach to work towards this goal by setting up a distributed network of ground stations which will ensure a 24/7 communication window - first tracking, then communicating with satellites.

Hacking MFPs (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

We have decided to continue our research onto PostScript realms - an old, very powerful and nicely designed programming language, where (as a coincidence or not, given it's numerous security flaws) Adobe owns most PostScript interpreters instances. This time we demonstrate that PostScript language, given it's power, elegance and Turing-completeness, can be used more than just for drawing dots, lines and circles - and to a certain extent it can be a hacker's sweet delight if fully mastered. We will be presenting a real-life implementation of unusual PostScript APIs (along with it's dissection and reconstructed documentation) that interact with various levels of OS and HW, implementation we have found in a TOP10 printer vendor product line. Also, we will investigate whether a PostScript-based (hence platform-independent) virus (18+ years after first proposals of such theory) can be acomplished, thus giving theoretical hints and few building blocks in this direction. We will also present some very constructive uses of the PostScript language in the creative (i.e. non-destructive) hacking direction. In the end, we will try to summarize our conclusions and possible solution for all parties involved (vendors, users, sysadmins, security experts). With this research we hope we can prove that entire printer industry (devices, printing software/drivers/subsystems, publishing and managed services) have to be rethought security-wise, so that it can withstand in the long run the current security landscape and threats. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4871.en.html

Wed, 28 Dec 2011 01:00:00 +0100

Despite their wide presence in our lives, baseband chips are still nowadays poorly known and understood from a system point of view. Some presentations have hilighted vulnerabilities in GSM stacks across various models of basebands (cf. 27c3: _All your baseband are belong to us_ by R-P. Weinmann). However none of them actually focused on the details of how a baseband operating system really works. This is the focus of our presentation. From the study of a simple 3G USB stick equipped with a Qualcomm baseband, we will discuss how to dump the volatile memory, reverse-engineer the proprietary RTOS, and ultimately execute and debug code while trying to preserve the real-time system constraints. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4735.en.html

The Science of Insecurity (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

Why is the overwhelming majority of common networked software still not secure, despite all effort to the contrary? Why is it almost certain to get exploited so long as attackers can craft its inputs? Why is it the case that no amount of effort seems to be enough to fix software that must speak certain protocols? about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4763.en.html

Marriage From Hell: On the Secret Love Affair Between Dictators and Western Technology Companies (28c3)

Tue, 27 Dec 2011 01:00:00 +0100

While it's old news that authoritarian regimes regularly rely on censorship and surveillance technology supplied to them by Western companies, 2011 was a year (thanks, in part, to the Arab Spring) when it became a hot issue in the public debate. While politicians on both sides of the Atlantic have recently committed to ban the sale of such technologies to dictators, it's not clear whether such measures would prove effective (or merely drive the sale of such technologies underground) or simply stimulate the growth of Chinese, Russian and Indian companies. More disturbingly, there is still very little awareness – at least among the general public – that many of the tools that are currently exported to authoritarian states have been designed to help fight "The Global War On Terror" and are thus inextricably linked to domestic policies of Western states. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4897.en.html

Towards a Single Secure European Cyberspace? (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

The "European Great Firewall" was the way that European civil rights organizations has addressed the proposal to create a "single European cyberspace". Surely other lectures will describe the technicalities of the proposal. This lecture will go beyond that, describing a vulnerability that the proposal reveals in the power structures of the European and world governance, that could be exploited by the hackerdom if the war is understood as a value to be avoided. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4802.en.html

The future of cryptology: which 3 letters algorithm(s) could be our Titanic? (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

The lessons and best practices of the titanic will be extracted. Are we ready? This will be a co-presentation (Jean-Jacques Quisquater / David Samyde) and occasional friendly exchange, with point and counter-point of different contrasting views on the impact of solving integer factorization and some other difficult problem in cryptography. The idea is to perform a provocative comparison between the 'unbreakable' RSA algorithm and the unsinkable Titanic. Receiving his RSA Conference Lifetime Achievement Award, Rivest said that it has not been demonstrated mathematically that factorization into primes is difficult. So “Factoring could turn out to be easy,” and according to him “maybe someone here will find the method”. Since 1994 and Shor's algorithm, the danger of quantum computer is known: breaking RSA in polynomial time. Factoring large numbers is conjectured to be computationally infeasible on classic non quantum computers. No efficient algorithm is known and the research in the last 30 years did not show enormous progress. Iceberg existence is predicted but not shown yet. According to Rivest a variety of alternative schemes have been developed in the decades since RSA was published, and a new system could probably be adopted quickly. This relies on solving factorization only, but several other cases can be considered, in some of them the action to replace RSA with a new algorithm could require more work than initially planned (solution to discrete logarithm). Managing the risk and the threat of the resolution of any major problem used in cryptography is crucial. This presentation challenges the conventional thinking using lessons learned from history. RSA users are everywhere so what could be the consequences of a break in the real world? What were the errors made on the Titanic? Can the best practices used be improved or just translated into a new scheme? What would be the impact of solving the RSA assumption on cryptography? The outline is: History of factorization Titanic primes and RSA keys Complexity, classes of algorithms and practical costs Risk analysis and Threat management Probability estimation and proactive monitoring From best to worst case Best methods and lessons learned Multiple scenari (Im)possibility of accurate prediction What to expect and how to be ready Conclusion Andrew Grove, former CEO of Intel said "Only the paranoid survive". Forecasting the presence of a strategic inflection point is hard. What to expect at the time of the next major cryptanalysis breakthrough? What history teaches? What remains to be done? Are we ready? about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4710.en.html

Die Meldungen aus Sachsen in diesem Jahr wirkten für alle, die nicht dort wohnen, ein bisschen, als kämen sie von einem sehr weit entfernten Stern. In regelmäßigen Abständen werden Dinge bekannt, die jeweils einzeln früher zum Rücktritt von Ministern geführt hätten. Funkzellenabfrage, §129-Verfahren, die Durchsuchung eines Pfarrers, Aberkennung der Immunität eines Fraktionsvorsitzenden wegen Rädelführerschaft: umfassende Kriminalisierung von Protesten gegen Nazis, und zwar weit bis in die "Mitte der Gesellschaft". Offline-Überwachung und -Drangsalierung sind in Sachsen Alltag. Der Talk gibt einen Überblick über den Stand der Dinge und warnt davor, sich (außerhalb Sachsens) gemütlich schaudernd zurückzulehnen.

Deceiving Authorship Detection (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

Stylometry is the art of detecting authorship of a document based on the linguistic style present in the text. As authorship recognition methods based on machine learning have improved, they have also presented a threat to privacy and anonymity. We have developed two open-source tools, Stylo and Anonymouth, which we will release at 28C3 and introduce in this talk. Anonymouth aids individuals in obfuscating documents to protect identity from authorship analysis. Stylo is a machine-learning based authorship detection research tool that provides the basis for Anonymouth's decision making. We will also review the problem of stylometry and the privacy implications and present new research related to detecting writing style deception, threats to anonymity in short message services like Twitter, examine the implications for languages other than English, and release a large adversarial stylometry corpus for linguistic and privacy research purposes. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4781.en.html

Resilience Towards Leaking or Why Julian Assange Might Be Wrong After All (28c3)

Fri, 30 Dec 2011 01:00:00 +0100

In his now (in)famous pamphlet "Conspiracy as Governance" Julian Assange (JA) argues about the need for leaking as an efficient way to destroy "unjust" groups as the neo-feudalistic ones - luring the conspiracy theory leaning hacker community into his belief system. Eventually, JA used a biologistic argument on the benefits and drawbacks that uncontrolled leaking might pose for "just" and "unjust" systems, arriving at the conclusion that "unjust" systems are hurt more and thus will be less viable, essentially being destroyed by more "just" systems. While an innovative proposal, the underlying assumptions on complexity, network theory, and especially the evolutionary perspectives were never critically assessed. Some blogs and media raised questions on details and potential threats to innocent bystanders. Still, fundamental problems with the philosophy were never addressed. This paper argues against the general validity of such theories. In particular, we will refute some of the biologistic arguments. Theoretical biology has long ago pointed out the hidden complexity in evolutionary processes and as such the envisioned "leaking revolution" might be a limited artifact: there might even arise situations where the leaking envisioned and encouraged by Wikileaks and the like can actually strengthen some "conspiracies". In this paper I will describe some research questions, that should be answered before given the “leaking philosophy” an unconditioned “thumbs-up”. Empirically, for example, a potential strengthening is illustrated by the rise of a 'neo-feudalistic economy', which is linked closely to the paradigm of "intellectual property" as it is to the security-financial-political complex. The players have effectively created a closed network or a "conspiracy" and might be resilient towards Wikileaks-like attacks. The paper concludes with an alternative to that proposal; in particular, a way to deal with the 'conspiracy' that might be coined the rise of the neo-feudalistic society (which in itself is a self-sustainable, self-amplifying feedback loop, not necessarily a conscious conspiracy). about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4741.en.html

Software is becoming more and more important in organizing response to all kinds of crises, whether that means activists responding to an unjust government or aid workers helping with the aftermath of a disaster. Security often isn't the first thing people think about in these situations -- they have work to get done, just like the rest of us, and many of these tools are built in the heat of the moment.

Tue, 27 Dec 2011 01:00:00 +0100

New to 2011, Packet-in-Packet exploits allow for injection of raw radio frames into remote wireless networks. In these exploits, an attacker crafts a string that when transmitted over the air creates the symbols of a complete and valid radio packet. When radio interference damages the beginning of the outer packet, the receiver is tricked into seeing only the inner packet, allowing a frame to be remotely injected. The attacker requires no radio, and injection occurs without a software or hardware bug. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4766.en.html

Security Log Visualization with a Correlation Engine (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

This brief session focuses on the visualization of actual security incidents, network forensics and counter surveillance of covert criminal communications utilizing large data sets from various security logs and a very brief introduction to correlation engine logic. Visually displaying security or network issues can express the risk or urgency in a way a set of dry logs or other methods might not be able to. Additionally, many organizations rely on a more singular approach and react to security events, many times from a high false positive rate source such as isolated intrusion prevention or firewall alerts, or relying only on anti-virus alerts. Utilizing a correlation engine (especially open source) or similar applications could offer a method of discovering or in some cases proactively detecting issues. The research discussed involves analysis and interrogation of firewall, intrusion detection and prevention systems, web proxy logs and available security research.

Post Memory Corruption Memory Analysis (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

Pmcma is a tool aimed at automating the most time consuming taskes of exploitation. It for instance determine why an application is triggering a segmentention fault, evaluate if the faulting instruction can be used to write to memory or execute arbitrary code, and list all the function pointers potentially called from a given point in time by an application. Pmcma is a totally new kind of debugger, which allows for easy experimentation with a process in memory by forcing it to fork. The exact replicas of the process created in memory can then be intrumented while keeping the properties (eg: state of variables, ASLR, permissions...) of the original process.

Rootkits in your Web application (28c3)

Wed, 28 Dec 2011 01:00:00 +0100

XSS bugs are the most widely known and commonly occurring Web vulnerability, but their impact has often been limited to cookie theft and/or simple actions, such as setting malicious email filters, stealing some data, or self-propagation via an XSS worm. In this work, I discuss practical approaches for exploiting XSS and other client-side script injection attacks, and introduce novel techniques for maintaining and escalating access within the victim's browser. In particular, I introduce the concept of _resident XSS_ where attacker-supplied code is running in the context of an affected user's main application window and describe its consequences. I also draw analogies between such persistent Web threats and the traditional rootkit model, including similarities in the areas of embedding malicious code, maintaining access, stealthy communication with a C&C server, and the difficulty of detecting and removing attacker-supplied code. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4811.en.html

Meet the Netherlands: a nation filled with techno-optimists protecting our freedom by puting in place restrictions on what you can do, reducing our privacy and have technology as a solution for anything and everything. When you make a trip we store your details for two years, your airplane meal selection from two years earlier is good data to test with and when migrating the government website we keep the old website running in an unmaintained state. If you have nothing to hide nothing can go wrong and there is nothing you can do. Well not quite. What would happen if you play the system? If you would take the train and hack the card? What if you were to pick up the resistance you face and use it in your advantage. No matter what the costs would carry on? If you would take some data and show the failures? Not just once but a full month long and call that month Leaktober. What if you would publicly call the failures with our personal data? Ultimately you make a difference. You change the law, you changes the rules of the game and you really can raise the question if storing all that data is really needed. Ultimately people really start to doubt if this is the right way to go. This is a strategic and tactical story on how you can regain some privacy and data protection. Even though for a journalist this should be normal work, thanks to some people these things become very personal. It ends in criminal prosecution, legal threats, insults, a successful counter hack and ultimately a lot of benefits. But standing up for a cause does work as long as you focus on the stories you want to bring. My story is about hacking the system from the inside, overcoming fear and showing bureaucrats that hackers are people too. The talk is a lessons learnt how a few people can change a nation with hacker beliefs if they really want to. A guideline on how to make a difference by hacking the system you want to change. Where you can even make huge mistakes, but with some luck you can win a world. How you can make your critical voice be heard. Zillions of lessons learnt. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4903.en.html

New Ways I'm Going to Hack Your Web App (28c3)

Thu, 29 Dec 2011 01:00:00 +0100

Writing secure code is hard. Even when people do it basically right there are sometimes edge cases that can be exploited. Most the time writing code that works isn’t even the hard part, it’s keeping up with the changing attack techniques while still keeping an eye on all the old issues that can come back to bite you, straddling the ancient world of the 90’s RFCs and 2010’s HTML5 compatible browsers. A lot like how Indiana Jones bridges the ancient and the modern... Except for Indiana Jones 4. Let’s never talk about that again. Ever. Take Facebook, Office 365, Wordpress, Exchange, and Live. These are applications that had decent mitigations to standard threats, but they all had edge cases. Using a mix of old and new ingredients, we’ll provide a sampler plate of clickjacking protection bypasses, CSRF mitigation bypasses, "non-exploitable" XSS attacks that are suddenly exploitable and XML attacks where you can actually get a shell; and we'll talk about how to defend against these attacks. about this event: http://events.ccc.de/congress/2011/Fahrplan/events/4761.en.html
