Isn't it a good idea to transfer eg an .wav file, which can carry malware inside (header, data etc.), to ASCII text file via hexdump? I would have achieved a non-executable format. It is still executable with a text editor but the malware can't cause any harm/execution because .wav and with it the malware code is transferred to Hex values/ASCII.
If I am correct, the .txt format doesn't have a header or are complicated like eg the .wav format, so there is no place for the malware.
Purpose: to have a worst case scenario backup so you can always attach the storage media to host, if all binaries are gone, without worrying of possible OS background events that potentially execute the malware code. ASCII text file which carries the hex values can always be transferred back to binary in let's say a test environment (besides the OS is clean and don't do any other changes) with working only with copies to find the malware.
I am a little bit confused about this, and I can't find much information about that specifically talks about the same kind of purpose or possible vulnerabilities.
