1:Search copy/paste to find the registration box location:
2:Back to the registration function:
3:Enter the verification code verification function:
1-1EB27BB9792E62BC13A77708C279D580AF1B16059CA949E53036FB3F0F3 |
This string should be the private key, the one below
rax = sub_10019c610(&var_30, rbx, r15) |
This is where the input string is really judged, follow up to see the implementation
4:Verification algorithm:
Here, we only need to modify the return value:
loc_10019c77d: mov al , bl ; CODE XREF=sub_10019c610+477, sub_10019c610+488, sub_10019c610+714 add rsp, 0x60 pop rbx pop r14 pop rbp ret |
Change mov al,bl to mov al,0x1, you don’t even need nop padding
5:After exporting the executable file, any registration code can be activated
