目录 收起 x86 汇编 buffer overflow attack 参考 x86 汇编 x86架构的32位和64位的call convention还是有一些区别的,但是返回地址放在哪里是没有变的,都是放在bp的上面。 栈帧(stack-frame),由两个指针来标记,即栈指针(stack pointer)和帧指针(frame pointer),可能有的汇编没用frame pointer,例如RISC-V汇编...
最后附一张常用指令对应的机器码,如果一个程序中包含了某一块,就可以被利用攻击。 这篇写了几个基于buffer overflow的攻击和保护措施,想更清楚理解可以去做attack lab,会有更清晰的认识~
需要注意的是,非可执行栈只是使得在栈上运行 shellcode 变得不可能,但它并不能防止缓冲区溢出攻击,因为在利用缓冲区溢出漏洞后,还有其他运行恶意代码的方式,比如返回到 libc(return-to-libc)攻击。我们为这种攻击设计了一个单独的实验室。如果你有兴趣,请参考我们的 Return-to-Libc Attack 实验室的详细信息。
1. Buffer Overflow Attack [45 pts + optional bonus 15 pts ] 1.1 Turning off Countermeasures Before starting this lab, we need to make sure the address randomization countermeasure is turned off; otherwise, the attack will be difficult. You can do it using the following command: ...

The learning objective of this lab is for students to gain first-hand experience of the buffer-overflow attack. This attack exploits a buffer-overflow vulnerability in a program to make the program by- pass its usual execution sequence and instead jump to alternative code (which typically starts...

最近做了一个buffer overflow的mini-project,用ssh登陆一个本地的virtualBox运行的Linux,利用buffer overflow获取root权限。详细过程请观看视频。 参考论文 - Smashing The Stack For Fun And Profit 内存layout: 黑客入门 - 堆栈溢出攻击 (buffer overflow attack)... ...
