密码管理软件破解。
运行软件,来到注册处,填上注册信息。(当然了随便了)
用ice下断:
bpx hmemcpy
按ok
被拦截.....
按几下f12来到该程序段,再按f10停在这里:
:0041D539 6888130000 push
00001388
:0041D53E 8B5508
mov edx, dword ptr [ebp+08]
:0041D541 52
push edx
:0041D542 E8990EFFFF call
0040E3E0 *不要按了,这里是出错框!
啊!对了,一路上你会碰到,几段代码:
:0041D49E E85D640000 call
00423900 *这里算码!
:0041D4A3 83C404
add esp, 00000004
:0041D4A6 8985FCFEFFFF mov dword
ptr [ebp+FFFFFEFC], eax
:0041D4AC 81BDFCFEFFFF92A71901 cmp dword ptr [ebp+FFFFFEFC],
0119A792 *对输入的注册码经过复杂计算后比较
