I read a paper by Alisa Shevchenko (semi-famous vulnerability researcher, who used to work for Kasperski Labs) a year or two ago that suggested successful modern malware is defined by its ability to adapt. As such the language itself is less important, apart from that you know it inside and out (and that it's Turing complete, so no HTML, lol). What's more important is that the program can change in order to either avoid detection and/or removal, or, if you're interested in anti-malware, to recognise and shift to take account of the way the malware is itself changing... So if, say, a virus was appending arbitrary bytes to the end of its own file to avoid detection, a clever anti-virus might be programmed to look for just the part of the virus file that was always the same. Or cleverer, it might reverse engineer the algorithm adding the bytes, and recognise the patterns in which they occurred as an additional clue that this was a malicious program.
Hello Adesam. I feel this question is vague. I believe malware to be malicious software. That software can be coded in many coding languages, perhaps depending on the target system. I believe there is no straight foward answer to your question. Also HTML is not a programming language, it is a markup language.
C, C++, C#, Java, Python and others.
Manual thanks for your comment,but i would like to build an app like that
Sonic Peter David Carter nice comment
