本实验设计为一个黑客拆解二进制炸弹的游戏。我们仅给黑客（同学）提供一个二进制可执行文件bomb和主函数所在的源程序bomb.c，不提供每个关卡的源代码。程序运行中有6个关卡（6个phase），每个关卡需要用户输入正确的字符串或数字才能通关，否则会引爆炸弹（打印出一条错误信息，并导致评分下降）！
要求同学运用GDB调试工具和objdump反汇编工具，通过分析汇编代码，找到在每个phase程序段中，引导程序跳转到“explode_bomb”程序段的地方，并分析其成功跳转的条件，以此为突破口寻找应该在命令行输入何种字符串来通关。
本实验要求解决Phase_1(15分)、Phase_2(10分)、Phase_3(10分)、Phase_4(10分)、Phase_5(10分)。通过截图把结果写在实验报告上。
#思路、#代码分析及最后的成绩截图
首先，先 cd 到bomb的文件里面，
3. 利用gdb调试工具来破解Phase1中的神秘字符串
$ gdb bomb
在0x8048b22处设置断点，运行并打印0x8049678地址的值
(gdb) b *0x8048b22
(gdb) r
(gdb) p (char*)0x8049678
记录答案，对下一关进行破解。
(gdb) c
第一关：
知识点：string，函数调用，栈
可以看到0x8048b2c和0x8048b31指令中分别放入了两个字符串，一个在地址0x80497c0中，另一个在%eax中。而%eax是函数phase_1的mov 0x8(%ebp),%eax 传递过来的参数，所以依此可以判断0x8(%ebp)的内存地址中的值是我们输入的字符串，而0x80497c0则可能是程序中已经存储在代码中的一个字符串。
那么，找到这个内存地址中的字符串便能解决问题了。那么如何去寻找呢，
所以，密码就是：Public speaking is very easy.
关键点在于，找到 退出函数 的地方和 引爆炸弹的地方。
第二关：
这样，就发现了第一个数字必须为1。
初始时，A[1]=1。所以，A[2] = A[1] * 2 = 2，A[3] = A[2] * 3 = 6，A[4] = A[3] * 4 = 24，A[5] = A[4] * 5 = 120，A[6] = A[5] * 6 = 720。
if ([0] != 1) explode_bomb();
for (int i = 1; i <= 5; i++) {
if ( (i+1) * A[i-1] != A[i])
explode_bomb();
} 第三关：
爆炸了。
sscanf() - 是C语言中从一个字符串中读进与指定格式相符的数据的函数。
sscanf传入的参数为：ebp-0x4,ebp-0x5, ebp-0xc地址；格式字符串地址；输入的字符参数地址。
ebp-0xc存第一个数， ebp-0x5存第二数，ebp-0x4第三个数。
从这就可以看出，要输入的是一个整数，一个字符，一个整数。
第一个数字要小于7。
<sscanf@plt>，猜测sscanf可能是C语言的内部函数，于是查到其定义为：int sscanf(const char *str, const char *format,…)，给出一个使用实例：sscanf(“s 1”, “%s %d”, str, &a)，函数返回2（因为接收了2个参数），str为char*类型，保存”s”；a为int类型，保存1。
我们试试倒推
我们看到，只要是标注了 int 的语句，最后跳转到 8048c8f 都有希望结束！！！！
希望来了！！！
求第一个数要小于等于7，那么使用最简单0进行测试，这样不用计算就可以跳转到明显的位置 ，就是 0x80497eb存储的内容—0x8048be0；
ebp-0x4存储的为第三个数，大小为0x309， 转10进制为：777。 同时，设置了bl 为 0x71。并跳转到0x8048c8f。
bl 为 0x71。第二个输入的又是 字符型 ，对照ASC码表：
字符串值为0x71，换算成字符为 ‘q’。
所以其中一个答案为： 0 q 777。
这道题的答案不为一，根据第一个参数的选择不同而不同。
第四关：
这段代码还有一个 func4 的函数，有不祥的预感…..
首先，又是 sscanf，老套路，我们先看一下 0x8049808字符串内容。
看来是一个整数！
这么看来，成功的关键就是，输入一个大于0的数字，这个数字作为参数，使得返回值为 55。
接下来就看看函数内容了：
当参数为1的时候，在8048cd0行，mov $0x1,%eax，将1放入了 eax里面，然后退栈，所以，当参数为1时候，返回值为1；
代码应该是这样的：
int func4(int a) {
if (a <= 1)
return 1;
else
return func4(a-1) + func4(a-2);
} 算法相当于：
f0=1
f1=1
f2=f1+f0
f3=f2+f1
......
fn=f(n-1)+f(n-2)
写代码算一下：
#include<iostream>
using namespace std;
int func4(int a) {
if (a <= 1)
return 1;
else
return func4(a - 1) + func4(a - 2);
}
int main()
{
int i;
for (i = 0;i < 1000;i++)
{
if (func4(i) == 55)
{
cout << i << endl;
break;
}
}
return 0;
}得出结果是9。
所以，答案是9！！！
第五关
第五关的代码如下：
在之间出现了两个字符串的地址，一个是0x804b220，另一个是0x804980b ，那么，我们先看看那是什么字符串：
看来是”isrveawhobpnutfg\260\001”和”giants”。
因为，这个循环做了6次，而且，匹配的字符串”giants”也是六个字符，所以，一定是和”giants”比较，但是怎么比较呢？
要在”isrveawhobpnutfg\260\001”中间取到”giants”的字符顺序是 15 0 5 11 13 1，这样是不是说明直接输入”giants”就可以了呢？
所以，很明显，不是，为什么呢？
因为，输入的是 字符ASC码二进制后四位的数字为这六个数字，所以，还是翻翻ASC码表吧！
我们就选择第二列吧，第二列比较好玩，哈哈哈哈，?05;=1（记得一定要是英文，半角的符号），或者是0O5KM1等等都给可以…..
第六关
这是第六关的整个汇编的代码：
原来是一个地址。
代码大概是这样的：
for (int i =0; i<=5; i++){
for (int j = i+1; j<=5; j++){
if (A[i]<= 6&&(A[i]!=A[j]))
{
continue;
}
else
explode_bomb();
}
}
所以，这一关输入的元素就只有 1，2，3，4，5，6；
但是，不是按照这个顺序输入的！！！！（不会告诉你，我为什么知道的，哈哈哈哈哈）
按照排列组合，A(6,6)=6*5*4*3*2*1=720 种 答案。所以范围已经缩小了。
8048e02: 31 ff xor %edi,%edi // i清零
8048e04: 8d4d e8 lea -0x18(%ebp),%ecx //数组首地址A
8048e07: 8d45 d0 lea -0x30(%ebp),%eax //ebp-0x30的地址
8048e0a: 8945 c4 mov %eax,-0x3c(%ebp) //存放于ebp-0x3c中
8048e0d: 8d76 00 lea 0x0(%esi),%esi

8048e13: bb01 00 00 00 mov $0x1,%ebx // j = 1
8048e18: 8d04 bd 00 00 00 00 lea 0x0(,%edi,4),%eax //eax = edi * 4
8048e1f: 89c2 mov %eax,%edx
8048e21: 3b1c 08 cmp (%eax,%ecx,1),%ebx //A[i] 与 j比较
8048e24: 7d12 jge 8048e38 <phase_6+0xa0> //小于的话，进入循环
8048e26: 8b04 0a mov (%edx,%ecx,1),%eax //eax = A[i]
8048e29: 8db4 26 00 00 00 00 lea 0x0(%esi,%eiz,1),%esi
8048e30: 8b76 08 mov 0x8(%esi),%esi //esi+0x8的值给esi
8048e33: 43 inc %ebx //j++
8048e34: 39c3 cmp %eax,%ebx //A[i] == j 停止循环
8048e36: 7cf8 jl 8048e30 <phase_6+0x98>
8048e38: 8b55 c4 mov -0x3c(%ebp),%edx //获得ebp-0x30地址
8048e3b: 8934 ba mov %esi,(%edx,%edi,4) //esi存入新数组中
8048e3e: 47 inc %edi
8048e3f: 83ff 05 cmp $0x5,%edi
8048e42: 7ecc jle 8048e10 <phase_6+0x78>
记得刚刚我们看到那个节点是一个地址，从代码可以看出每次移动了0x8，然后传递，现在，调用：
gdb) x /3x 0x804b26c ，这个指令的意思为：以16进制格式显示地址0x804b26c处3个单位，默认每个单位四字节的内容。
这说明是6个节点的内容，尾部是一个指针指向下一个节点的内容。
for (int i =0; i<=5; i++){
for (int j =0; A[i]> j; j++){
node = node.next;
}
P[i]= node;
}所以，P[i]这个数组所放的节点顺序，就是输入数字的顺序！！比如：输入 4，2，5，3，1，那就是 node[4],node[2],node[5],node[3],node[1],的排列顺序！！
这段代码就只是起连接作用：
8048e44: 8b 75 d0 mov -0x30(%ebp),%esi //取ptr地址
8048e47: 8975 cc mov %esi,-0x34(%ebp) //存于ebp – 0x34中
8048e4a: bf01 00 00 00 mov $0x1,%edi // i = 1
8048e4f: 8d55 d0 lea -0x30(%ebp),%edx //ebp-0x30地址
8048e52: 8b04 ba mov (%edx,%edi,4),%eax //ptr[i] => eax
8048e55: 8946 08 mov %eax,0x8(%esi) //ptr[i-1]->next = ptr[i]
8048e58: 89c6 mov %eax,%esi //esi = ptr[i]
8048e5a: 47 inc %edi
8048e5b: 83ff 05 cmp $0x5,%edi
8048e5e: 7ef2 jle 8048e52 <phase_6+0xba>
8048e60: c746 08 00 00 00 00 movl $0x0,0x8(%esi)
8048e67: 8b75 cc mov -0x34(%ebp),%esi //最后一个结点next 赋0 那么，看看这样子排列究竟有什么用呢？
最后，链表的判断：
原来，是想把按照节点中 数字大小的顺序输入数字！！！
节点的数字是什么呢？我们再看看：
原来分别是
0x0fd
0x2d5
0x12d
0x3e5
0x0d4
0x1b0所以，大小顺序就是，4，2，6，3，1，5。
所以答案就是：4 2 6 3 1 5 ！！！！！！！
整个花了大概25个小时才做完。非常不容易，很多汇编语言在百度上解释是有错误的。
