控制流完整性(Control Flow Integrity, CFI)是一种旨在保护程序免受控制流劫持攻击的安全技术。它通过确保程序的控制流(即程序执行过程中控制路径的顺序)始终按照预定的正确路径执行,从而防止攻击者利用漏洞改变程序的执行流程。CFI 主要防御的是控制流劫持攻击,比如返回导向编程(ROP)和跳转导向编程(JOP)等利用漏洞控制...

Control-flow integrityARM CoreSightProtecting safety-critical Cyber-Physical Systems (CPS) against security threats is becoming a growing necessity. Due to the high level of network integration, CPS pose new targets to remote code-reuse attacks, such as Return-Oriented Programming (ROP). An ...
本文讨论的原理基于Control-Flow Integrity Principles, Implementations, and Applications这篇论文。 1 回顾为什么需要CFI 1.1 控制流劫持 攻击者能够通过控制流劫持来获取目标机器的控制权,甚至进行提权操作,对目标机器进行全面控制。 早期的攻击通常采用代码注入的方式,通过上载一段代码,将控制转向这段代码执行。 代码重...
1 引言 1.1 控制流劫持 计算机经常受到旨在控制软件行为的外部攻击。这种攻击作为数据传输并驻留在程序存储器中,就触发预先存在的软件缺陷。通过利用这些漏洞,攻击可以破坏执行并获得对软件行为的控制。 在二进制安全中,大部分的漏洞利用方式是劫持控制流,接着使程序按照攻击者的攻击思路运行下去。控制流劫持是一种危害...
