Control Flow Guard (CFG) is a highly-optimized platform security feature that was created to combat memory corruption vulnerabilities.
Exploring Control Flow Guard in Windows 10 (trendmicro.com) 本文主要来自上面两篇文章,自己做一个记录罢了。 CFG 通过在间接跳转(Indirect Call)前插入校验代码(比如 call dword ptr ss:[ebp-8] 等等 ),检查目标地址的有效性,进而可以阻止执行流跳转到预期之外的地点, 最终及时并有效的进行异常处理,避免引发...
这个分支必须转移控制以退出guard语句出现的代码段。它可以用控制转移语句如return,break或continue做这件事,或者它调用了一个不返回的方法或函数,例如fatalError()。 相比于可以实现同样功能的if语句,按需使用guard语句会提升我们代码的可靠性。 它可以使你的代码连贯的被执行而不需要将它包在else块中,它可以使你处理...
Windows的CFI实现称为Control Flow Guard(CFG),因为实际的性能要求,不可能做到非常精确的CFI,因此,实际在windows上部署的CFI是粗粒度的、前向CFI。首先,粗粒度的CFI是:所有的有效跳转地址为一个全局的集合,即不精确的为每一个间接跳转指定一个有效跳转地址;其次,什么叫做前向CFI:只考略call,jump的直接跳转和间接跳...
1] What is Control Flow Guard and how does it work Control Flow Guard is a feature that makes it harder for exploits to execute arbitrary code through vulnerabilities such asbuffer overflows. As we know, software vulnerabilities are often exploited by providing unlikely, unusual, or extreme data...

How Do I Tell That a Binary is under Control Flow Guard? How Does CFG Really Work? What is Control Flow Guard? Control Flow Guard (CFG) is a highly-optimized platform security feature that was created to combat memory corruption vulnerabilities. By placing tight restrictions on where an appli...
See/guard (Enable Control Flow Guard)for additional info. If you are building your project from the command line, you can add the same options. For example, if you are compiling a project called test.cpp, usecl /guard:cf test.cpp /link /guard:cf. ...
