As such, there are still a lot devices all over the world subject to root attacks. The different patching status of various vendors causes fragmentation, and vendors usually don't provide the exact up-to-date kernel source code for all devices, so it is extremely difficult to patch vulnerable devices in scale. We will provide stats of the current Android kernel vulnerability landscape, including the device model population and the corresponding vulnerability rates. Some vulnerabilities with great impact but slow fixing progress will be discussed. The whole community strives to solve this problem, but obviously this cannot be done discretely with limited hands. In this talk, we present an adaptive android kernel live patching framework, which enables open and live patching for kernels.

We will cover pre-infection, post-infection and advanced persistency techniques name on aws that allows an attacker to access staging and production environments, as well as read and write data and even reverse its way from the cloud to the the corporate datacenter. This session will cover several methods of infection including a new concept - "account jumping" for taking over both paas (e.g. ElasticBeans) and iaas (EC2, ec2 Containers) resources, discussing poisoned amis, dirty account transfer, as well as leveraging S3 and CloudFront for performing aws specific credentials thefts that can easily lead to full account access. We will then discuss the post-infection phase and how attackers can manipulate aws resources (public endpoints like ec2 ips, elastic ips, load balancers and more) for complete mitm attacks on services. We will demonstrate how attackers code can be well hidden via lambda functions, some cross zone replication configuration and the problem with storage affinity to a specific account. We'll examine hybrid deployments from the cloud and compromising the on premise datacenter by leveraging and modifying connectivity methods (HW/sw vpn, direct connect or cloud hub). Finally, we'll end with a discussion on best practices that can be used to protect from such attacks such as bastion ssh/rdp gateways, understanding the value of casb based solutions and where they fit, leverage audit and hsm capabilities nanyang in aws as well as looking. Presented by dan Amiga dor Knafo Although 0-day exploits are dangerous, we have to admit that the largest threat for Android users are kernel vulnerabilities that have been disclosed but remain unfixed. Having been in the spotlight for weeks or even months, these kernel vulnerabilities usually have clear and stable exploits; therefore, underground businesses commonly utilize them in malware and apts. The reason for the long periods of remaining unfixed is complex, partly due to the time-consuming patching and verification procedures, or possibly because the vendors care more about innovating new products than securing existing devices.
As a bonus for the breakers, we'll explore and legs demonstrate exploitations of the emergent risks in these more volatile standards, to include multiple vulnerabilities uncovered quite literally during our research for this talk (which will hopefully be mitigated by d-day). Presented by Bryant Zadegan ryan Lester aws users, whether they are devops in a startup or system administrators tasked with migrating an enterprise service into the cloud, interact on a daily basis with the aws apis, using either the web console or tools such. When working with the latter, authentication is done using long-lived access keys that are often stored in plaintext files, shared between developers, and sometimes publicly exposed. This creates a significant security risk as possession of such credentials provides unconditional and permanent access to the aws api, which may yield catastrophic events in case of credentials compromise. This talk will detail how mfa may be consistently required for all users, regardless of the authentication method. Furthermore, this talk will introduce several open-source tools, including the release of one new tool, that may be used to allow painless work when mfa-protected api access is enforced in an aws account. Presented by loic Simon The widespread adoption of aws as an enterprise platform for storage, computing and services makes it a lucrative opportunity for the development of aws focused apts.
I'll examine why these vulnerabilities happened, how the inclusion of weakened cryptography in a protocol impacts security, and how to better design and implement cryptographic protocols in the future. Having been involved in the discovery of all three export vulnerabilities, i'll distill some lessons learned from measuring and analyzing export cryptography into recommendations for technologists and policymakers alike, and provide a historical context for the current "going dark and Apple. Presented by david Adrian Through cooperation between browser vendors and standards bodies in the recent past, numerous standards have been created to enforce stronger client-side control for web applications. As web appsec practitioners continue to shift from mitigating vulnerabilities to implementing proactive controls, each new standard adds another layer of defense paper for attack patterns previously accepted as biography risks. With the most basic controls complete, attention is shifting toward mitigating more complex threats. As a result of the drive to control for these threats client-side, standards such as SubResource Integrity (sri content Security policy (csp and http public key pinning (hpkp) carry larger implementation risks than others such as http strict Transport Security (hsts). Builders supporting legacy applications actively make trade-offs between implementing the latest standards versus accepting risks simply because of the increased risks newer web standards pose. In this talk, we'll strictly explore the risks posed by sri, csp, and hpkp; demonstrate effective mitigation strategies and compromises which may make these standards more accessible to builders and defenders supporting legacy applications; as well as examine emergent properties of standards such as hpkp.
Presented by, alvaro munoz oleksandr Mirosh, could a worm spread through a smart light network? This talk explores the idea, and in particular dives into the internals of the Philips hue smart light system, and details what security has been deployed to prevent this. Examples of hacking various aspects of the system are presented, including how to bypass encrypted bootloaders to read sensitive information. Details on the firmware in multiple versions of the Philips hue smart lamps and bridges are discussed. This talk concentrates on examples of advanced techniques used in attacking iot/embedded hardware devices. Presented by colin o'flynn tls has experienced three major vulnerabilities stemming from "export-grade" cryptography in the last year-freak, logajm, and Drown. Although regulations limiting the strength of cryptography that could be exported from the United States were lifted in 1999, and export ciphers were subsequently deprecated in tls.1, Internet-wide scanning showed that support for various forms of export cryptography remained widespread, and that attacks exploiting. In this talk, i'll examine the technical details and historical background for all three export-related vulnerabilities, and provide recent vulnerability measurement data gathered from over a year Internet-wide scans, finding that 2 of browser-trusted ipv4 servers remain vulnerable to freak, 1 to logjam, and.

In the paper, we pinpoint the key portions in each oauth protocol flow that are security critical, but are confusing or unspecified for mobile application developers. We then show several representative cases to concretely explain how real implementations fell into these pitfalls. Our findings have been communicated to vendors of the vulnerable applications. Most vendors positively confirmed the issues, and some have applied fixes. We summarize lessons learned from the study, hoping to provoke further thoughts about clear guidelines for oauth usage in mobile applications presented by, yuan tian eric Chen shuo chen yutong pei robert Kotcher patrick tague. Jndi (java naming and Directory Interface) is a java api that allows clients to discover and look up data and objects via a name. These objects can be stored in different naming or directory services such as rmi, corba, ldap, or dns.
This talk will present a new type of vulnerability named "jndi reference Injection" found on malware samples attacking java applets (cve ). The same principles can be applied to attack web applications running jndi lookups on names controlled by attackers. As we will demo during the talk, attackers will be able to use different techniques to run arbitrary code on the server performing jndi lookups. The talk will first present the basics of this new vulnerability including the underlying technology, and will then explain in depth the different ways an attacker can exploit it using different vectors and services. We will focus on exploiting rmi, ldap and corba services as these are present in almost every Enterprise application. Ldap offers an alternative attack vector where attackers not able to influence the address of an ldap lookup operation may still be able to modify the ldap directory in order to store objects that will execute arbitrary code upon retrieval by the application lookup operation. This may be exploited through ldap manipulation or simply by modifying ldap entries as some Enterprise directories allow.
Kernel exploitation using the browser as an initial vector was a rare sight in previous contests. This presentation will detail the eight winning browser to super user exploitation chains (21 total vulnerabilities) demonstrated at this year's Pwn2Own contest. We will cover topics such as modern browser exploitation, the complexity of kernel Use-After-Free exploitation, and the simplicity of exploiting logic errors and directory traversals in the kernel. We will analyze all attack vectors, root causes, exploitation techniques, and possible remediations for the vulnerabilities presented. Reducing attack surfaces with application sandboxing is a step in the right direction, but the attack surface remains expansive and sandboxes are clearly still just a speed bump on the road to complete compromise.
Kernel exploitation is clearly a problem which has not disappeared and is possibly on the rise. If you're like us, you can't get enough of it; it's shell on earth. Presented by, matt Molinyawe jasiel Spelman abdul-aziz hariri joshua smith, oauth has become a highly influential protocol due to its swift and wide adoption in the industry. The initial objective of the protocol was specific: it serves the authorization needs for websites. However, the protocol has been significantly repurposed and re-targeted over the years: (1) all major identity providers,. G., facebook, google and Microsoft, have re-purposed oauth for user authentication; (2) developers have re-targeted oauth to the mobile platforms, in addition to the traditional web platform. Therefore, we believe that it is necessary and timely to conduct an in-depth study to demystify oauth for mobile application developers. Our work consists of two pillars: (1) an in-house study of the oauth protocol documentation that aims to identify what might be ambiguous or unspecified for mobile developers; (2) a field-study of over 600 popular mobile applications that highlights how well developers fulfill the authentication. The result is really worrisome: among the 149 applications that use oauth, 89 of them (59.7) were incorrectly implemented and thus vulnerable.

The things that need to be better are technical in nature, and guide research priorities that are outright not being addressed at present. Essentially, i'd like to provide a model for comprehending the Internet as it stands, that prevents harm to it (how much could we have used EC2 if ssh was illegal) while providing the useful resources to promote its continued operation. We can't keep screwing this up forever. Ntia has noted half (!) of the population warily backing away. Let's talk about how it really works, so we can discuss how we can do it better. Presented by, dan Kaminsky presented daddy by, jeff Moss. Briefings, the winning submissions to Pwn2Own 2016 provided unprecedented insight into the state of the art in software exploitation. Every successful submission provided remote code execution as the super user (system/root) via the browser or a default browser plugin. In most cases, these privileges were attained by exploiting the microsoft Windows or Apple fuller os x kernel.
we call the Internet, was not our first attempt at making a global data network that spanned the globe. It was just the first one that worked. In this talk, i'll lay out what I see as how the Internet actually works. It's increasingly likely that there will be attempts to *change* the principles of the net, and the reality is that widespread hacking is the exact sort of force that brought us this working-ish system in the first place. We need to talk about the values of cryptography, of open software and networks, of hackers being a force for measurable good. We need to talk about how infrastructure like dns - it was there 25 years ago, we can imagine it will be there 25 years from now - acts as foundation for future development in a way that the api of the hour doesn't. Things do need to be better, and we need to talk about the role of government in that.
