My first post here. I thought you all might find this interesting. I was doing some malware research today and came across a tutorial about how to use a hex editor and file splitter to change the signature of a virus/trojan/etc to make it undetected by malware scanners. I never realized how simple it is to pass an existing virus by security software. Makes me glad I'm running Linux. lol I just found I can't post links, so if you query google for "how to make a virus undetectable hex editor", the tutorial I read will be the first result. Hope you all find it interesting.
