Purple Teaming: One year after going from full time breaker to part time fixer

A little over a year ago I made the transition from external security consultant to internal offensive security engineer at Facebook. I went from a full time breaker to part time fixer. This talk is aimed at providing lessons learned and documenting the mindset changes I've made over the last year that I feel can be used by the industry as a whole. I've broken the lessons learned into three primary buckets; Red, Blue, and Purple and the talk will hopefully bring value to anyone working in their respective bucket or assist in their creation/continuing of purple teaming at their company.

CHRIS GATES BIO

Chris joined Facebook in April 2014 as an Offensive Security Engineer. Chris has extensive experience in redteaming, network and web application penetration testing as well as other Information Operations experience working as an operator for a DoD Red Team and other Full Scope penetration testing teams (regular pentesting teams too). Chris holds a BS in Computer Science and Geospatial Information Science from the United States Military Academy at West Point and holds his... redacted...no one cares anyway. In the past, he has spoken at the United States Military Academy, BlackHat, DefCon, Toorcon, Brucon, Troopers, SOURCE Boston, OWASP AppSec DC, DerbyCon, Hashdays, DevopsDays DC. Chris is also a cofounder of NoVAHackers. Blog: carnal0wnage.attackresearch.com  Twitter: @carnal0wnage

Spread Spectrum Satcom Hacking: Attacking the Globalstar Simplex Data Service

Recently, there have been several highly publicized talks about satellite hacking. However, most only touch on the theoretical rather than demonstrate actual vulnerabilities and real world attack scenarios. This talk will demystify some of the technologies behind satellite communications and do what no one has done before - take the audience step-by-step from reverse engineering to exploitation of the GlobalStar simplex satcom protocol and demonstrate a full blown signals intelligence collection and spoofing capability. I will also demonstrate how an attacker might simulate critical conditions in satellite connected SCADA systems.

In recent years, Globalstar has gained popularity with the introduction of its consumer focused SPOT asset-tracking solutions. During the session, I'll deconstruct the transmitters used in these (and commercial) solutions and reveal design and implementation flaws that result in the ability to intercept, spoof, falsify, and intelligently jam communications. Due to design tradeoffs these vulnerabilities are realistically unpatchable and put millions of devices, critical infrastructure, emergency services, and high value assets at risk.

COLBY MOORE BIO

Colby Moore is Synack's Manager of Special Activities. He works on the oddball and difficult problems that no one else knows how to tackle and strives to embrace the attacker mindset during all engagements. He is a former employee of VRL and has identified countless 0-day vulnerabilities in embedded systems and major applications. In his spare time you will find him focusing on that sweet spot where hardware and software meet, usually resulting in very interesting consequences.

VANESSA TEAGUE

The New South Wales iVote System: Security Failures and Verification Flaws in a Live Online Election

In the world's largest-ever deployment of online voting, the iVote Internet voting system was trusted for the return of 280,000 ballots in the 2015 state election in New South Wales. During the election, we performed an independent security analysis of parts of the live iVote system and uncovered severe vulnerabilities that could be leveraged to manipulate votes, violate ballot privacy, and subvert the verification mechanism. These vulnerabilities do not seem to have been detected by the election authorities before we disclosed them, despite a pre-election security review and despite the system having run in a live state election for five days. One vulnerability, the result of including analytics software from an insecure external server, exposed some votes to complete compromise of privacy and integrity. At least one parliamentary seat was decided by a margin much smaller than the number of votes taken while the system was vulnerable. We also found fundamental protocol flaws, including vote verification that was itself susceptible to manipulation. This incident underscores the difficulty of conducting secure elections online and carries lessons for voters, election officials, and the e-voting research community. 

VANESSA TEAGUE BIO

Vanessa Teague is a research fellow in the computing and information systems department at the University of Melbourne, Australia. She has worked on cryptographic protocols for electronic voting ever since finishing a CS PhD at Stanford on cryptographic protocols for economic games. Australia's unusual voting system constitutes a special challenge. She also spends a lot of time explaining to parliamentarians and electoral officials that requirements for transparency, privacy and verifiability apply to computerised voting too.

Practical Intel SMEP Bypass Techniques on Linux

The Linux kernel has always been an appealing target for exploit developers due to the exploitation complexity associated with user space processes (ASLR, NX, Canaries, Fortify, RELRO, etc.). Common ret2usr (return-to-user) attacks typically redirect kernel control flow to data residing in user space: a corrupted function or data structure pointer that triggers a privilege escalation payload in user space. These attacks were successful until around 2013 before the introduction of 3rd generation Intel Core processors (Ivy Bridge) with SMEP support. SMEP (Supervisor Mode Execution Protection) is a hardware feature that prevents attempts to execute code (at CPL = 0) residing in user space pages. This kernel-hardening approach is now widely adopted and effectively mitigates common exploitation patterns of kernel vulnerabilities.

This presentation introduces practical Linux SMEP bypasses involving in-kernel ROP and spraying techniques. We will demonstrate how to convert an existing exploit code to a fully weaponised SMEP-aware exploit. This talk will concentrate on a specific kernel vulnerability and OS version to demonstrate the bypass but the exploitation techniques presented are generic and can be applied to other Operating Systems that employ explicit sharing of the virtual address space among user processes and the kernel.

VITALY NIKOLENKO BIO

Vitaly is a security researcher specialising in malware analysis and exploit development. He has a solid academic background in programming languages, algorithms and cryptography. He is currently focused on Linux kernel exploitation techniques (SMEP/SMAP, ASLR bypasses) and the associated countermeasures. He currently works as a pentester and has performed countless penetration tests for large financial and governmental institutions.

High Performance Fuzzing

Security conference talks related to fuzzing tend to focus on distributed frameworks or new proof-of-concept engines. This talk will take a look at how to get the most performance out of your engine designs and fuzzing cluster for long term deployments. We will discuss topics like fork servers, static binary rewriting, patching Windows kernel to bypass memory limits and more tricks that have yet to be included in fuzzing talks. We have successfully applied these techniques to create a high performance port of AFL that targets binaries as well as speed up previous work on concolic execution and automated test generation. We will also compare effectiveness of various black box fuzzing approaches including model inference and directed fuzzing engines against a new benchmark composed of real-world vulnerabilities.
Highlights include:
  • Highest performance program tracing options for coverage and dataflow
  • Using bootkits to bypass software memory limits in Windows
  • RAM disk options on Windows
  • Harnessing copy-on-write on Windows
  • High speed automatic test generation
  • Benchmark set of real vulnerabilities for testing fuzzers

Abusing Adobe Reader¹s JavaScript APIs

Adobe Reader¹s JavaScript APIs offer a rich set of functionality for document authors. These APIs allow for processing forms, controlling multimedia events, and communicating with databases, all of which provide end-users the ability to create complex documents. This complexity provides a perfect avenue for attackers to take advantage of weaknesses that exist in Reader¹s JavaScript APIs.

In this talk, we will provide insight into both the documented and undocumented APIs available in Adobe Reader. Several code auditing techniques will be shared to aid in vulnerability discovery, along with numerous proofs-of-concept which highlight real-world examples. We¹ll detail out how to chain several unique issues to obtain execution in a privileged context. Finally, we¹ll describe how to construct an exploit that achieves remote code execution without the need for memory corruption.

JOSHUA “KERNELSMITH” SMITH

High-Def Fuzzing: Exploring Vulnerabilities in HDMI-CEC

The HDMI (High Definition Multimedia Interface) standard has gained extensive market penetration. Nearly every piece of modern home theater equipment has HDMI support and most modern mobile devices actually have HDMI-capable outputs, though it may not be obvious. Lurking inside most modern HDMI-compatible devices is something called HDMI-CEC, or Consumer Electronics Control. This is the functionality that allows a media device to, for example, turn on your TV and change the TV’s input. That doesn’t sound interesting, but as we'll see in this presentation, there are some very surprising things an attacker can do by exploiting CEC software implementations. Then there's something called HEC or HDMI Ethernet Connection, which allows devices to establish an Ethernet connection of up to 100Mbit/s over their HDMI connections (newer HDMI standards raise the speed to 1Gbit/s).

Don't think your mobile phone implements CEC? You might be wrong. Most modern Android-based phones and tablets have a Slimport(r) connection that supports HDMI-CEC. Ever heard of MHL (Mobile High-Definition Link)? Think Samsung and HTC (among other) mobile devices, and many JVC, Kenwood, Panasonic, and Sony car stereos – as many as 750 million devices in the world so far. Guess what? MHL supports HDMI-CEC as well. Let's explore, and own, this attack space.

JOSHUA “KERNELSMITH” SMITH BIO

Broadcasting Your Attack: Security Testing DAB Radio In Cars

Digital Audio Broadcasting (DAB) radio receivers can be found in many new cars and are in most cases integrated into an IVI (In-Vehicle Infotainment) system, which is connected to other vehicle modules via the CAN bus. Therefore, any vulnerabilities discovered in the DAB radio stack code could potentially result in an attacker exploiting the IVI system and pivoting their attacks toward more cyber-physical modules such as those concerned with steering or braking. This talk will discuss the complex protocol capabilities of DAB and DAB+ and describe the potential areas where security vulnerabilities in different implementations may exist. I will discuss the use of Software Defined Radio in conjunction with open source DAB transmission software to develop our security testing tool (DABble). Finally I will talk about some of our findings, the implications of exploiting DAB-based vulnerabilities via a broadcast radio medium and what this could mean for the automotive world.

VoIP Wars: Destroying Jar Jar Lync

Enterprise companies are to use Microsoft Lync 2010/2013 (a.k.a Skype for Business 2015) services as call centre, internal communication, cloud communication and video conference services. It is based on the VoIP and instant messaging protocols, and supports multiple client types such as Microsoft Office 365, Microsoft Lync, Skype for Business, IP phones and teleconference devices. Also the official clients are available for mobile devices (e.g. Windows phone, Android and iOS), desktops (Mac, Linux and Windows) and web applications developed with .NET framework.

Although the Microsoft Lync platform developed with the new technologies, it still suffers the old VoIP, teleconference and platform issues. Modern VoIP attacks can be used to attack Microsoft Lync environments to obtain unauthorised access to the infrastructure. Open MS Lync frontend and edge servers, insecure federation security design, lack of encryption, insufficient defence for VoIP attacks and insecure compatibility options may allow attackers to hijack the enterprise communication. The enterprise users and employees are also the next generation targets for these attackers. They can attack the client soft phones and handsets using the broken communication, invalid protocol options and malicious messaging content to compromise sensitive business assets. These attacks may lead privacy violations, legal issues, call/toll fraud and intelligence collection.

Attack vectors and practical threats against the Microsoft Lync ecosystem will be presented with newly published vulnerabilities and Microsoft Lync testing modules of the Viproy VoIP kit developed by the speaker. This will be accompanied by live demonstrations against a test environment.  A brief introduction to Microsoft Lync ecosystem  Security requirements, design vulnerabilities and priorities  Modern threats against commercial Microsoft Lync services  Demonstration of new attack vectors against target test platform

DNS as a Defense Vector

DNS enables everything else on the Internet -- both good and bad. By watching what bad guys do with their DNS configurations and offering them differentiated (that is to say, poor) service, defenders can re-level the playing field in our favour. In this one-hour talk, Dr. Paul Vixie, CEO of Farsight Security, will explain what DNSSEC and TSIG (Secure DNS and Transaction Signatures) are and why you might want them, explain what RRL and RPZ (Response Rate Limiting and Response Policy Zones) do and why you absolutely do want them, then demonstrate SIE (the Security Information Exchange) which collects data from cooperating sensors all over the Internet and shares this telemetry with qualified non-profit and for-profit researchers. If there's enough time there will also be a demonstration of DNSDB, a passive DNS database. (Otherwise that demo will occur in the hotel bar area later on.)

PAUL VIXIE BIO

Vixie has been contributing to Internet protocols and UNIX systems as a protocol designer and software architect since 1980. He wrote Cron (for BSD and Linux), and is considered the primary author and technical architect of BIND 4.9 and BIND 8, and he hired many of the people who wrote BIND 9. He has authored or co-authored a dozen or so RFCs, mostly on DNS and related topics, and of Sendmail: Theory and Practice (Digital Press, 1994). His technical contributions include DNS Response Rate Limiting (RRL), DNS Response Policy Zones (RPZ), and Network Telemetry Capture (NCAP). He earned his Ph.D. from Keio University for work related to DNS and DNSSEC, and was named to the Internet Hall of Fame in 2014.
