The Dark Tangent
Black Hat Founder and Director Jeff Moss is becoming one of the most sought-after voices in information security. He has spent the last 17 years as founder and director of Black Hat and DefCon, two of the most important security conferences in the world. Moss is uniquely qualified with his ability to bridge the gap between the underground researcher community and law enforcement, between the worlds of pure research and responsible application.
Moss speaks frequently before a wide range of audiences on the topic of computer and information security. Recently in 2009 Moss was appointed to the Homeland Security Advisory Council to provide advice and recommendations to the Secretary on matters related to homeland security. He moderated a panel at RSA 2009 on core infrastructure security threats. Moss also was a keynote speaker at the DOD Cybercrime Conference in St. Louis in 2009, spoke at the first CodeGate conference in South Korea in 2008, the first DeepSec conference in Vienna in 2007, as was a panelist at the Democracy, Terrorism and the Open Internet panel in 2005 in Madrid. He has also been a frequent panelist at RSA. Moss has been interviewed and appeared on TV shows ranging from CNN to G4 TechTV, in magazines Business Week to Computer World, as well as numerous documentaries dealing with internet, law, ethics, hacking, and privacy. In addition Moss has contributed to “Stealing the Network,” a series of books that combine stories that are fictional with technology that is real.
Prior to Black Hat Briefings, Jeff was a director at Secure Computing Corporation where he helped establish the Professional Services Department in the United States, Asia, and Australia. Jeff has also worked for Ernst & Young, LLP in their Information System Security division. Jeff graduated with a BA in Criminal Justice from Gonzaga University.
Topic: Adobe Reader Fast Break — the Tale of Two Exploits in TFCup 20/21
Adobe Reader is always a juicy target for attackers, but it seems mysterious for hackers like me who are not familiar with Windows ecosystems. In 2020, I tried to do a fast break of Adobe Reader for a hacking competition TianfuCup. Based on my previous experience of hacking other modern systems, I achieved remote code execution in Adobe Reader successfully. In this talk, I will share the path I went through for learning and hacking an old but new target like Adobe Reader.
slipper is a hacking game enthusiast.
He used to play in hacking games like Pwn2Own, DEF CON CTF, GeekPwn, Tianfu Cup… In 2013, He founded 0ops team, one of the most prestigious and powerful CTF team in China. From 2018 to 2021, he host DEF CON CTF (2018-2021) as a core member of Order Of Overflow(OOO).
He has pwned many targets in public hacking shows - iPhone8, iPhone13 Pro, PlayStation 4, Cisco ASA, QEMU, Safari, Firefox, macOS, Docker,Parallels Desktop, Cent OS, Ubuntu and Adobe Reader. Sometimes he livestreams hackings.
Topic: Web 3.0 is Bug Bounty 2.0
DeFi, NFT, Metaverse are the recent heated topics. Every hack on the blockchain can range from a few hundred bucks to half a billion dollar loss. It's no surprise the demand for blockchain security surges. In this talk, I'll talk about how to get into Web3 bug bounty hunting and showcase few bugs we found that easily add up to $200k+ bounty rewards.
Filedescriptor has been in the bug bounty scene for 8 years and counting, and has been the No.1 on Twitter's Bug Bounty program since 2016. Currently, he is transitioning to Web3 bug bounty hunting. He works at Cure53.
Topic: BROWSER HACKING WITH ANGLE
This presentation gives the basic knowledge of the ANGLE project and examines how to use ANGLE in WebGL/WebGL2 of web browsers. In this talk we analyze the types of vulnerabilities and root causes that occurred in ANGLE and we analyze exploitable vulnerabilities and explain how to obtain RCE in macOS (iOS is also affected, but PAC bypass is not covered in this presentation.)
We will start with a basic introduction to WebGL / WebGL2 component and how to use ANGLE in your web browser followed by a look at the following vulnerabilities -

Topic: AD Attack Paths Demystification
For decades, Windows AD has been something that every analyst has loved and hated. Used in over 90% of enterprises, various manufacturers and software developers prioritize being compatible. On the other hand, many old services still heavily rely on AD. Decoupling an AD environment is difficult when maintenance and operation personnel are overly dependent, resulting in some uncomfortable security settings with maintenance and operations. Due to these problems and other historical factors, numerous underground network administrators (or Shadow Admins) have often taken advantage of improper AD configurations. With the rising number of cyberattacks targeting and exploiting AD, enterprises can no longer afford to ignore AD security issues and the business-altering risk they can produce.
In this presentation, we'll review different AD security topics, explore practical errors, and look at the challenges faced by AD analysts today from real-world cases, such as permission inventory and insufficient permission separation. We aim to demystify ways for hackers to escalate their privileges by utilizing existing/proprietary tools to dissect attack incidents. In the end, we provide the audience with a deeper understanding of their own AD and guide them to approach their AD security.

Topic: Ghost Process - Hide Process In Kernel Evading PatchGuard
Antivirus software can scan malicious processes. By detecting each process, the antivirus collects the information of the target process like the image path.
Malware also needs to evade antivirus, one of the methods is to hide the process itself. Due to PatchGuard, operations such as kernel patch and hook are forbidden after 64-bit Windows XP and Windows Server 2003.
However, there still be other ways to bypass PatchGuard. For example, we can achieve the conditions that how PatchGuard detects the kernel patch, or leverage the unprotected area of PatchGuard to do kernel hook.
This talk will introduce how malware hides the process itself from the kernel by DKOM and infinity hook that can bypass PatchGuard and antivirus. Windows API to enumerate processes in user mode and kernel mode are also analyzed and found it losing its effect under the attack.

Topic: A New Trend for the Blue Team - Using a Practical Symbolic Engine to Detect Evasive Forms of Malware/Ransomware
Blue Teams and anyone on the defensive side face various challenges when it comes to reverse engineering suspected malware or ransomware binaries, especially ones with obfuscation techniques such as variants, embedded exploits and complex ransomware. First, identifying whether the sample is even worth the effort (what makes it unique/challenging/new), and second, choosing either static, dynamic analysis, or both! With static analysis, you give up the ability to detect obfuscated malicious programs only visible during run-time, and dynamic analysis is both labor and time intensive, and requires a high-degree of skill and experience, not to mention the threat of the binary escaping your sandbox emulation or virtualization environment.
We believe there may be a new tool in the Blue Team's toolbox, through the use of a symbolic execution engine to detect and analyze suspected malware/ransomware binaries. A practical symbolic engine can help by parsing through many of the possible execution paths of the binary, and having these pathways represented as symbols. This engine can help provide malicious execution paths analysis with relatively low computing resources, analyze contextual relationships based on instruction semantics, taint and fuzzy identification of obfuscated APIs.
Using our practical symbolic engine based on the combination and improvement of academic and practical research, you can identify and detect various exploit, techniques, and multiple malware/ransomware variants via symbolic signature attack techniques and ransomware behaviors in a fully static situation. Even if the malware binary is obfuscated, we can still statically analyze it and detect it effectively. Our plan is to make our engine available to the community via open source during Black Hat USA 2022, to help give back to the infosec community and help Blue Teams save time on an ongoing and difficult problem.
