How to replace string in exe using hex editor?

Question

Programming

Hello, I would like to know how to do this and whether it can be done by inserting a string of a different length.

Answer 1

Open file, find line, replace, save.
The ability to change the length depends on many factors: compiler, linker, luck.

Answer 2

As described above, making a shorter string is no problem. To make a string longer than the original one, you need to find a free space in the file filled with zeros (usually this happens at the end of the segment), enter the necessary text there, and then change the line call address to a new one (you need a HEX editor with a disassembler and minimal concepts of assembly mnemocodes) .

Answer 3

Take a hex editor, open the file, edit.
In 90% of cases, inserting a string of a different length will not work, since most often in the code the data comes first, and then the code. When inserting data, all links in the code will fly.
Insert a shorter line - it will, do not forget to put 00 at the end of the line.
