破解华夏银行U盾全屏幕遮挡
【前提】
华夏银行在线登录系统
或者
华夏银行Client登录系统

需要破解华夏银行的全屏锁定UI。
1、点击托盘--Login--全屏锁定。
2、插入U盘---Web登录--全屏锁定
3、转账最后一步,确认--全屏锁定。
为什么要去掉这个全屏锁定?
因为自动转账的一些软件无法正常使用了。
【破解过程】
1、先破解 托盘启动的方式,即:certd_I3000_HXB.exe
2、OD加载,查找字符串: UNICODE "Login successfully!"
锁定:
004074A3 68 B4C14100 push 0041C1B4 ; UNICODE "Login successfully!"
3、关键位置
这个Call 就是点击 Login 的位置:
0040707A 55 push ebp
0040707B 8BEC mov ebp, esp
0040707D 81EC DC010000 sub esp, 1DC
00407083 53 push ebx
00407084 56 push esi
00407085 57 push edi
00407086 8BF1 mov esi, ecx
00407088 6A 01 push 1
0040708A E8 D9F60000 call <jmp.&MFC42u.#6330>
0040708F 8B3D B4764100 mov edi, dword ptr [<&USER32.SendMes>; USER32.SendMessageW
00407095 6A 00 push 0
00407097 BB 0A110000 mov ebx, 110A
0040709C 6A 09 push 9
0040709E 53 push ebx
0040709F FFB6 9C030000 push dword ptr [esi+39C]
004070A5 FFD7 call edi
逐步跟踪,查找全屏显示的Call,最后锁定:创建全屏窗口:
00407176 8D45 C0 lea eax, dword ptr [ebp-40]
00407179 50 push eax
0040717A FF75 8C push dword ptr [ebp-74]
0040717D 6A 04 push 4
0040717F E8 44B5FFFF call 004026C8 ; 创建全屏窗口
分析结果: 在2个地址,直接Jmp,就可以实现。

最后,进行分析,有下面文件需要破解:
1、破解Exe方式,需要破解
安装目录\certd_I3000_HXB.exe
安装目录\certd2ka_hxb.exe
安装目录\shuttle_certd3003_hxb.exe
2、破解Web方式登录,需要破解
C:\Windows\System32\hxkey2feitian.dll
