what is the difference between a runtime fud crypter and a scantime fud crypter?

how is the coding different?

[Mr Smith]

Scan time when you scan it Run time when you run the malicous code

[Deathader]

FUD scantime means the file is FUD when you scan it. It will be picked up by AV's when ran.

FUD runtime means AV won't pick it up when it's run.

so what's the difference in the coding of them?

Scantime crypters encrypt the actual exe file. They then decrypt it, save it, then run it.

Runtime crypters decrypt the bytes, then run the bytes inside another process (such as explorer.exe). This way they aren't detected by AVs

Interesting, I now understand those two terms. I have my own question if the OP wouldn't mind. Could you use both scantime/runtime in one instance?

[TheHackingIdiot]

IN ONE INSTANCE? you mean make a file both scantime and runtime fud? yeah you can do that

The difference between runtime and scantime is obvious but I'd like to ask a question;

How exactly do you make a runtime crypter? I'm not asking for a tutorial but a basic understanding as what happens and how does it fool the AV, etc
