玩逆向有几年了，取之于民用之于民。
1.先分析第一个CM
对于没有VM的程序 最合适的方式就是直接放到OD 直接看字符串或者关键字符 看可疑字符串找函数头 Ctrl+R 找上级回溯地址
So……从字符串看发现检测OD字样，双击进入然后找call 004034E0 $ 55 push ebp 头部 Ctrl+R 找上级回溯地址 00401E65 |. E8 76160000 call cm.004034E0
继续找00401E65的头部地址 00401D62 /$ 55 push ebp Ctrl+R 找上级回溯地址 00401D59 |> \E8 04000000 call cm.00401D62 继续找到头部地址 00401C52 /$ 55 push ebp
类推 00401BA4 |. E8 A9000000 call cm.00401C52 最终到 00401BA1 /. 55 push ebp // F2下段 让程序跑起来 （也可以用按钮事件 对于易语言可以直接忽略上面的文字直接用 FF 55 FC 5F 5E 直接下端 方法很多看个人喜欢）
2.跑起来后 编辑框随意输入key 程序断下 单步F7
到此处发现eax有类似MD5的数据出现 于是对地址0x4B2290 右键 -》查找参考 -》地址常量
找到有一个赋值的地址 双击进入（ ps：为何要找赋值的地址 因为只有赋值的地址才能知道具体数据是不是MD5 这样看起来只是类似 不能确定）
于是 进入到地址 0040149D |. A3 90224B00 mov dword ptr ds:[0x4B2290],eax
找到段首004010F2 /. 55 push ebp F2 下端 重新跑起来程序 看看数据来由
3.单步F8后的数据直接贴代码和注释

上面的注释中 理论上 疑惑的应该就是 取现行时间 其他应该通过eax 都很好理解和得出结论
对于随意一个 取现行时间的call F7 进入后
0046B2FD FF15 88814800 call dword ptr ds:[<&KERNEL32.GetLocalTim>; kernel32.GetLocalTime
0046B303 8D45 E0 lea eax,dword ptr ss:[ebp-0x20]
0046B306 50 push eax
0046B307 FF15 8C814800 call dword ptr ds:[<&KERNEL32.GetSystemTi>; kernel32.GetSystemTime
看到这两个函数 百度一下就会知道这个call 是 易语言的取现行时间
通过上面的单步分析 算法应该也是很好写的 可以无损破解 写注册机
注册机代码 我也贴一下 方便各位看官参考
爆破是比较简单的
.版本 2
.支持库 eAPI
.子程序 _按钮1_被单击
.局部变量 时间, 日期时间型
时间 ＝ 取现行时间 ()
编辑框1.内容 ＝ 到文本 ((取年份 (时间) ＋ 取月份 (时间) ＋ 取分钟 (时间)) × 32 ＋ 2020 － 取日 (时间)) ＋ “1992” ＋ 字符 (99) ＋ 到大写 (字符 (97)) ＋ 取文本右边 (取IP地址 (), 2) ＋ 到文本 (取年份 (时间)) ＋ 到文本 (取月份 (时间)) ＋ 到文本 (取日 (时间))
爆破的时候 也可以修改程序最后32位为修改保存后的程序字节集长度-32长度的字节集的md5数据 有点绕口 不过只要去程序的最后看一下数据就明白了

004159F0 89C7 mov edi,eax
004159F2 E8 39240000 call <jmp.&msvcrt.wcslen> ; 取 0041F2F0 压入的那四个数据的长度
004159F7 39F8 cmp eax,edi
004159F9 89C5 mov ebp,eax
004159FB 89F8 mov eax,edi
004159FD 0F4EC5 cmovle eax,ebp
00415A00 897424 04 mov dword ptr ss:[esp+0x4],esi
00415A04 891C24 mov dword ptr ss:[esp],ebx
00415A07 894424 08 mov dword ptr ss:[esp+0x8],eax
00415A0B E8 18240000 call <jmp.&msvcrt.wcsncmp> ; 对比文本
所以我们修改我们输入的假key前面四个字节为 69D8A5DE 后面清空00 让对比实现
继续单步 然后就出来了 成功信息框 顺便出来了 𪚥 zhe 这个字 也就
最后祝大家牛年大吉大利！发大财！希望坛主审核一下！
