 Posted: Tue Mar 01, 2016 10:57 am Post subject: Code Injection and return. Need helps, thanks. |
 |
|
How do I return to other lines in the code other than "returnhere" in the code injection template? For example:
1. I inject my code at line 100
2. I want to return to line 110 after the execution of my injected code.
How to do that? Thanks.

You can also do something like:
which will jump to the next instruction after the code injection plus 20 (hex!) bytes.

"returnhere" is just a label- a representation of an address. If you write your jump at derp.dll+100 and you want to return to derp.dll+110, then just write jmp derp.dll+110.

Thanks for the reply. A follow up question:
00 1F FA 88
In the code above, "1F" is one byte as well as "88", right?
@ParkourPenguin:
So I can jump to any module addresses, right? Thanks.

Yes. Or, you can jump to any other address you want to. CE will automatically translate the location of the module+offset into bytes, then use that in the machinecode. So you can jump to any address you want to, even if it's not a part of a module. For example, if you are using an AoB scan and you store the result into the symbol "aobaddy", then you could also write jmp aobaddy+10 and it'll work.
Also, yes, each sequence of 2 hexadecimal digits is 1 byte.
