DriverJack

DriverJack 简介 DriverJack 是一款旨在利用鲜为人知的 NTFS 技术加载有漏洞驱动程序的工具。这些方法通过劫持现有服务绕过系统上驱动服务的注册，并且还伪造驱动加载事件中显示的镜像路径。为进一步隐藏有漏洞驱动的存在，该攻击还利用了模拟文件系统只读绕过，在加载前替换已挂载 ISO 上的驱动文件内容。 模拟文件系统只读绕过 DriverJack 利用了将挂载在模拟文件系统上的文件重新映射到读写页以覆盖其内容的可能性。此只读绕过在 IoCdfsLib 中实现。 攻击概述 一旦 ISO...

BlackHat-Europe-2022

BlackHat-Europe-2022 从二进制中选择模式类似于 CVE-1337-Days 的漏洞 摘要 静态代码审查是发现漏洞变体和利用原语的有效方法，但静态分析最具挑战性的两个任务在于：从海量不同类型的漏洞中高效提取代码模式，以及从大量不同模块中高效搜索代码模式，尤其是对于像 Windows 这样的闭源软件。 本次演讲将讨论我们针对这两个挑战的实践与经验，主要涵盖我们如何针对不同的漏洞类型和利用原语提取四种独特的代码模式，以及如何借助我们的新型二进制代码模式搜索工具 Leviathan，在 Windows 上自动发现漏洞和利用原语。...
