请使用IDA Pro工具，反汇编bomb.exe
|
||||
并调试该程序。
|
||||
|
||||
bomb.exe将要求你输入多个密码，只有输入正确的密码，才能继续执行程序，否则将“爆炸”。
|
||||
|
||||
利用IDA Pro的反汇编、调试功能，你应该可以破解该炸弹！
|
||||
|
||||
bomb.exe需要一个参数，这个参数是你学号的后6位，例如092224
|
||||
|
||||
bomb.exe 092224
|
||||
超级二进制炸弹2024版，欢迎你！
|
||||
你需要不断依据提示，输入信息，以便解除二进制炸弹，一旦出错，哇哈哈....
|
||||
以前尝试正确的密码，可以写入到bomb.key文件中，一个密码一行
|
||||
请输入第1级的密码：dfaadfddfdf
|
||||
牛刀小试~你已经通过了第1级考验！
|
||||
请输入第2级的密码：1 3 4 5 7 8 10
|
||||
不错不错~你已经通过了第2级考验！
|
||||
请输入第3级的密码：1 3 4 5 7 8 10
|
||||
今夜没加班？ 你已经通过了第3级考验！
|
||||
请输入第4级的密码：1 3 4 5 7 8 10
|
||||
完美了~你已经通过了第4级考验！
|
||||
二进制炸弹之不可能任务，你的选择是继续前行（Y），或者放弃（N）
|
||||
友情提示：后面的代码，涉及到反调试、动态生成指令等，所以你要有思想准备......
|
||||
不可能任务，请输入突防指令：
|
||||
12345
|
||||
你已经通过了第5级考验，完成了不可能完成任务（终极考验）！
|
||||
不可能的...不可能的...指令和数据的世界已经混乱...SOS...

2017超级缓冲区炸弹
|
||||
|
||||
使用IDA Pro反汇编、调试bufbomb.exe文件。
|
||||
|
||||
你需要首先设置学号
|
||||
然后根据提示，输入一串特定的十六进制字符串，以便对bufbomb实现缓冲区溢出攻击。
|
||||
|
||||
例如：
|
||||
|
||||
2017超级缓冲区炸弹，欢迎你！
|
||||
============================
|
||||
你的通行密码是0X8E371DDA
|
||||
============================
|
||||
请输入攻击字符串（十六进制串）：00 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF
|
||||
|
||||
鸟还活着！
|
||||
不错哦，缓冲区溢出成功，而且getbuf返回0X8E371DDA
|
||||
|
||||
恭喜你！你已经成功偷偷运行了第1只木马!
|
||||
通过第1只木马测试
|
||||
|
||||
不错哦！第2只木马运行了，而且通行密码是正确的！(0X8E371DDA）
|
||||
通过第2只木马测试
|
||||
|
||||
厉害！第3只木马运行了，而且你修改了全局变量正确！global_value = 0X8E371DDA
|
||||
通过第3只木马测试
|
||||
|
||||
不错哦，缓冲区溢出成功，而且getbuf返回0X8E371DDA
|
||||
厉害！第4只木马运行了，而且你修改了全局变量正确！global_value = 0X8E371DDA
|
||||

2. Each function has a maximum number of operators (! ~ & ^ | + << >>)
|

that you are allowed to use for your implementation of the function.

The max operator count is checked by dlc. Note that '=' is not
|

counted; you may use as many of these as you want without penalty.
