During this talk we're going to discuss the security of the so called internet-of-things (IOT),and have a better understanding of what it's all about. This talk will give a broad overview of IOT , the major vulnerabilities that are out there, challenges that exist in securing the things , and what we as security people can do about it.
If you'd ever heard the IOT buzzword, and you want to know what it's all about, this talk is for you.
How can we really automate secure coding? Agile, DevOps, Continuous Integration, Orchestration, Static, Dynamic - There's an endless feed of Buzzwords, but how can we turn this into a practice that really works? In this session we will review real world examples of building a successful automation process for delivery of secure software in fast paced development environments.
In the proverbial game of cat-and-mouse between endpoint security vendors and malware writers, malware attacks have recently grown more sophisticated. More enterprises are losing ground to hackers, who are able to outmaneuver static and runtime solutions by constantly changing their attack strategies. In his presentation, Yair will break down the current set of techniques (signatures, static analysis, dynamic analysis, social cyber-intelligence) used to identify malware on mobile devices, and identify the pros and cons of these approaches. He will also explain why attackers constantly succeed in fooling these technologies, and explore the problem of false positive/false negative tradeoffs in such solutions. In order to demonstrate the aforementioned, Yair will create on stage a malicious mobile app live, which can bypass signatures, static and dynamic analysis approaches.
Audience will learn:
When attacking web applications, what do you do when there are no injection points? No false-assumptions? No logical errors? Most of the times you just move on, perhaps look for bad code in a different component or third party plugin. What if that target is just too important to give up on? What if your target is the most popular web platform in the world?
This talk will focus on the recent vulnerabilities found in WordPress core, one of the most securely written web apps in the world. We will begin with a carefully orchestrated race condition leading to Privilege Escalation, and all the way to SQL injection and persistent XSS attacks, in 20% of the top 1M sites on the Internet. We will dive deep into a system that seems un-penetrable, and analyze a chain of bugs no one thought exploitable, in order to describe one of the most interesting WebApp vulnerabilities in CMS history.
Join us for a journey through the eyes of one researcher who made it to core WordPress and lived, to get a glimpse of how one searches for vulnerabilities in massive code and how to catch oh-so-important developer misses.
File synchronization services, such as GoogleDrive, DropBox and others are becoming widespread, both with private and corporate use. These applications, while offering great convenience to their users, also provide a hacker with ideal platform for C2 infrastructure. Instead of setting up a new C2 server, an attacker simply needs to open a new cloud storage account, or even use the victims account as the platform.
In our presentation we will examine how common cloud synchronization services can be used by hackers to steal private and corporate data, remain persistent on infected machines and avoid perimeter detection mechanisms. All of this could be done from the attacker’s laptop, without any exploits and without writing server side code.
Objective: Understand risks & mitigations of MitC attacks
Cross-site search (XS-search) attacks circumvent the same-origin policy and extract sensitive information, by using the time it takes for the browser to receive responses to search queries. This side-channel is usually considered impractical, due to the limited attack duration and high variability of delays. This may be true for naive XS-search attacks; however, we show that the use of better tools facilitates effective XS-search attacks, exposing information efficiently and precisely.
We present and evaluate three types of tools: (1) appropriate statistical tests, (2) amplification of the timing side-channel, by `inflating' communication or computation, and (3) optimized, tailored divide-and-conquer algorithms, to identify terms from large `dictionaries'. These techniques may be applicable in other scenarios.
We implemented and evaluated the attacks against the popular Gmail and Bing services, in several environments and ethical experiments, taking careful, IRB-approved measures to avoid exposure of personal information.
The first is in the Android Platform and Google Play Services. The Platform instance affects Android 4.3-5.1, M (Preview 1) or 55% of Android devices at the time of writing. This vulnerability allows for arbitrary code execution in the context of many apps and services and results in elevation of privileges. In this talk we also demonstrate a Proof-of-Concept exploit against the Google Nexus 5 device, that achieves code execution inside the highly privileged system_server process, and then either replaces an existing arbitrary application on the device with our own malware app or changes the device’s SELinux policy. For some other devices, we are also able to gain kernel code execution by loading an arbitrary kernel module. We had responsibly disclosed the vulnerability to Android Security Team which tagged it as CVE-2015-3825 (internally as ANDROID-21437603/21583894) and patched Android 4.4 / 5.x / M and Google Play Services.
For the sake of completeness we also made a large scale experiment over 32,701 of Android applications, finding similar deserialization vulnerabilities, identified by CVE-2015-2000/1/2/3/4/20, in 6 SDKs affecting multiple apps. We responsibly (privately) contacted the SDKs’ vendors or code maintainers so they would provide patches. Further analysis showed that many of the SDKs were vulnerable due to weak code generated by SWIG, an interoperability tool that connects C/C++ with variety of languages, when fed with some bad configuration given by the developer. We therefore worked closely with the SWIG team to make sure it would generate more robust code — patches are available.
Hundreds of millions of Android devices, including those running Lollipop, the latest and most secure version of Android OS, can be hijacked. A comprehensive study has revealed the existence of multiple instances of a fundamental flaw within the Android customisation chain that leave millions of devices (and users) vulnerable to attack.
These vulnerabilities allow an attacker to take advantage of unsecure apps certified by OEMs and carriers to gain unfettered access to any device, including screen scraping, key logging, private information exfiltration, back door app installation, and more. In this session, Lacoon researchers will walk through the technical root cause of these responsibly-disclosed vulnerabilities including hash collisions, IPC abuse and certificate forging which allow an attacker to grant their malware complete control of a victims device. We'll explain why these vulnerabilities are a serious problem that in some ways can't be completely eliminated, show how attackers exploit them, demonstrate an exploit against a live device, and provide remediation advice.
