What are all possible ways , One can add strings to .rdata section of a Binary Executable?

I Was wondering What are all the possible ways people can mess with the executable’s .rdata Strings ?

Because I’ve actualy seen it .. But i do not have any idea how they do that .

Some random dude made like a copy of My executable but with more strings (Files Names) on an [x] offset that falls into .rdata section , which caused the Executable to map more files in the memory …

How is that even possible ?
