Tomatically demonstrating whether the vulnerabilities identified by static analysis can actually be exploited or not at run-time by an attacker. We adopted a formal and sound approach to automatically produce malicious payloads able to reproduce the dangerous behavior in vulnerable applications. The lack of exhaustive sanity checks when receiving messages from unknown sources is the evidence of the underestimation of this problem in real world application development. Despite a plethora of data security and protection standards and certifications, companies and their systems are still leaking information like a sieve. Zte axon 7 cheap Data Loss Prevention (DLP) solutions have often been touted as the "silver bullet" that will keep corporations from becoming the next headline. With deployment models ranging from a fat agent on an endpoint, to a blinky-lights box surveilling all network traffic, to some unified threat management gateway with DLP secret sauce, these solutions are ripe for bypass - or worse. This talk will discuss our research into a handful of DLP solutions, including their capabilities and their shortcomings. We will demonstrate flaws in administrative and programmatic interfaces and the inspection engines themselves.

SVG is an XML-based format for vector graphics. Modern web browsers support it natively and allow it to be styled using CSS and manipulated using JavaScript.

It is less well-known that SVG can contain its own JavaScript and can import external scripts and stylesheets. Consequently, from a browser security perspective, SVG must be treated like HTML; treating it like JPEG will lead to great suffering.

Return-oriented Programming (ROP) is a powerful exploitation technique used in nearly every exploit today. It maliciously combines short code snippets (gadgets) residing in shared libraries and the executable to bypass data execution prevention (DEP). As a consequence, several new control-flow integrity (CFI) mechanisms and tools have been recently proposed to thwart ROP attacks. For instance, kBouncer and ROPGuard both restrict return instructions to target a call-preceded instruction.

In addition, ROPecker and kBouncer force the adversary to invoke a long instruction sequence after a pre-defined number of short gadgets thereby preventing an attacker to execute a sequence of ROP gadgets. In general, these mechanisms significantly reduce the gadget space and make it challenging for an attacker to mount ROP attacks.

While others have hypothesized or even exploited weaknesses in some of these emerging CFI techniques, we provide the first comprehensive analysis thereof. Specifically, we conducted a security analysis of various recently proposed CFI solutions (including kBouncer, ROPGuard, ROPecker, and CFI for COTS binaries).

Our key contribution is in demonstrating that these techniques can be effectively undermined even when all their protection mechanisms are combined. In particular, we transformed existing (publicly available) exploits against Windows (which are detected by Microsoft EMET) into more stealthy attacks that bypass all recently proposed CFI techniques.

We show that our performed transformations require no specific assumptions, and demonstrate that a 1MB Windows library (kernel32. SSL has been around for decades and yet it keeps happening: new attacks are being discovered against TLS at a steady rate. The past year has seen its share of rogue CA certificates and critical vulnerabilities in TLS libraries that we have come to expect.

In this talk, I will present no less than three new attacks against the use of TLS on the web. The first one relies on a long-known cryptographic weakness in the protocol that can be combined with long-known issues in TLS implementations to re-enable a flavor of the 2009 renegotiation attack that was thought to be fixed. The second one exploits the truncation weakness known since SSL2 but left unsolved to bypass anti-stripping defenses (strict transport security) and steal secure cookies. The last one exploits vulnerabilities in the deployment of HTTPS, in particular, how HTTP servers process requests and manage certificates and sessions, to reach the holy grail of TLS attacks: full server impersonation of several thousands of websites, including Microsoft, Apple, Twitter, PayPal.

The three attacks have strong common points: they rely on an attacker that operates both at the TLS and HTTP levels, and they exploit misunderstandings and false assumptions between TLS libraries and applications. In the course of this talk, you will learn about the full capabilities of the "beastly" attacker that operates jointly at the transport and application levels and how they can be exploited.

You will also learn how to configure your HTTPS server to avoid being vulnerable to our virtual host confusion attacks, for which no simple universal fix exists. Lastly, I will try to disprove some misconceptions about TLS and privacy in the context of powerful network attackers.

Security research is a dangerous business. The threat of lawsuits or even prosecution hangs heavy over the heads of white hat hackers as well as black hats. How serious are these threats - and what can researchers do to avoid them, and maybe even fix the law? Two veteran digital rights lawyers - one who counsels companies and defends hackers, and another who is an expert in the DC policy game - and the lead strategist of a major security firm will use a game show format to share examples of legally risky research and ask the question: "Computer Crime or Legitimate Research?

While it might be convenient to think of cyberadversaries as ones and zeros, the reality is that systems are attacked and defended by human beings. As a result, it is important to understand the role deception plays in network operations.

This presentation draws upon traditional and emerging research on deception and associated game theories to help the audience understand how attackers might deceive them, how to recognize that deception, and how defenders can also deceive their attackers. Just as one should never bring a knife to a gun fight, a network defender should not rely on tired maxims such as "perimeter defense" and "defense in depth. This talk teaches you how to tap what we call the Library of Sparta - the collective written expertise codified into military doctrine.

Hidden in plain sight, vast free libraries contain the time-tested wisdom of combat at the tactical, operational, and strategic levels. This is the playbook nation-state adversaries are using to target and attack you. This talk will help you better understand how adversaries will target your organization, and it will help you to employ military processes and strategies in your defensive operations.

These techniques scale from the individual and small team level all the way up to online armies. Many people in the computer security community use words like "OPSEC," "Kill Chain," and "intelligence-driven" without fully understanding the underlying concepts.

Even worse, many show their ignorance by using military jargon incorrectly, thereby alienating clients, customers, and colleagues. These concepts are powerful and should not be ignored, but they must be well understood before they can be leveraged in your network.

This talk will include topics such as deception, electronic warfare, operations security, intelligence preparation of the battlefield, human intelligence collection, targeting, psychological operations, information operations, maneuver, and military cryptanalysis, among numerous others. Conventional wisdom at Black Hat is that that attacker will always win. Attackers have a clear intelligence advantage over defenders when it comes to vulnerabilities, malware, and open source information.

A key point of the talk will be helping defenders generate the intelligence, information, and disinformation advantage necessary to turn the tables. You will leave this talk with an entirely new arsenal of military-gr
