• Trellix's Threat Labs team discovered 8 zero-day vulnerabilities in the LNL-4420 access control panel
• The vulnerabilities could be exploited remotely without access to the system firmware
• The vulnerabilities allowed for full system control and remote manipulation of door locks
• The presentation includes a live demo of the exploit
• The access control panel is widely used across multiple industries, including education, real estate, healthcare, transportation, and government facilities
• Over 20 OEM partner vendors were also found to be vulnerable to the same issue
• The presentation emphasizes the need for timely updates and patches to prevent such vulnerabilities

• Type confusion vulnerabilities are a significant bug class that can weaken security and bypass mitigations like memory tagging and hardware solutions.
• CastGuard is a technology developed to solve illegal static downcasts in C++ to mitigate type confusion vulnerabilities.
• Dynamic cast, the current solution for downcasts, is difficult to apply to a large code base and has significant overhead.
• CastGuard is performant, has minimal impact on binary size and optimization, and can potentially be used to accelerate Dynamic cast.
• CastGuard is currently being tested in Hyper-V and will be rolled out to other Windows components in the future.

• The configuration of the immuno can be modified to perform DMA attacks to read and write anywhere in the main physical memory
• The IUN menu is a way to protect against DMA attacks, but it is not available by default on Ubuntu
• A basic stat buffer overflow can be used to gain access to the Wi-Fi chip
• Debug mode can be enabled to gain full distribution access
• The loader used to load firmware onto the chip can be exploited to perform a time of chat to time of fuse attack

• The speaker demonstrates how to exploit a man-in-the-middle vulnerability in the ASA's Adaptive Security Device Manager (ASDM) to steal credentials and gain access to the network.
• The speaker shows how to use hard-coded credentials to gain root access to the Firepower module's boot image and install malicious code.
• The speaker also discusses how to modify the Firepower install packages to install malicious code and trick victims into installing them.
• Mitigations include disabling the ASDM feature, rotating passwords, and retiring/replacing the Firepower module.
• The presentation emphasizes the importance of applying mitigating controls when patching is not an option.

• The Requiem is a generic and effective exploitation method that swaps kernel credentials to escalate privileges
• It can bypass CFI and work across different kernel versions and architectures
• Data-only attacks are powerful and can write universal exploits without dealing with CFI and ROP
• Mitigations in Linux kernel mostly focus on protecting control flow integrity, but there is a need for mitigations to protect data-only integrity
• The Requiem can actively escape from containers, which is not possible with Dirty Pipe

• The iOS emulator was developed to address the challenges posed by real devices, which are expensive, rare, and highly secure.
• The emulator aims to model actual hardware as closely as possible and supports a wide range of iOS versions, including iOS 14 to iOS 16.
• The emulator also supports custom CPU features by Apple and USB support, and allows for easy kernel debugging and fuzzing.
• The development process involved reverse engineering the device tree and building a stop model, followed by dynamic and static reverse engineering to understand hardware behavior and write emulation code.
• The emulator is open source and available for use in research.

• Spectre is a vulnerability that affects most modern CPUs and allows attackers to leak data across privileged levels
• Vendors released software and other defenses to prevent cross-privileged level data leaks
• The presenters tested the effectiveness of these defenses and found that they can be bypassed
• The presenters introduce a new primitive called branch history injection that can be used to bypass the defenses
• The presenters demonstrate how branch history injection can be exploited to leak kernel data
