can hackers hack ASP ?

No. I don't think so as ASP code will be executed in server side and will not appear in the client side (browser).
In terms of security of ASP, it all depends on the Windows Server and IIS. If someone can enter to the server, they can take all server side files but this is very hard as the hacker has to break through a series of protection systems including hardware firewalls.

Server side scripting codes (ASP, PHP, etc...) are considered safe as long as they stay in the server. Still there are certain methods to encrypt server side codes (including pre-compilation) to protect them.
