I've actually written an SF novel that takes place in the 22nd century, but the premise is that a William Gibsonian cyberpunk world is sharing an uneasy coexistence with magic that started working a few decades prior. So I combine a lot of combat mage stuff with traditional cyberpunk hacking in cyberspace. I've found that, at least for me, what worked when it came to the hacking/virtual combat sequences was to take advantage of written fiction's biggest strength; detail. You're not working with film, TV, or comic books, so trying to emulate cool visual fights in written form is tough work. But what you CAN do is "blow up" the minutiae of the hack, the hacker, the strategies being used.
So, for example in the Matrix movie, they focused on the martial arts fights, and only occasionally focused on the furious typing of Tank as the actual hacker doing the background work. With written fiction, you can reverse that. Really get into the hacker's head, give the IDEAS and the TACTICS the spotlight, instead of concentrating on brute virtual action. I mean, I've still got a little bit of virtual combat here and there taking place in some weird settings like a cathedral made of bones, but the real heart of the virtual combat is the software, and the usage of the software that acts as the backbone.
If you really want to see cyberspace hacking/combat done well, always go back to the classics. Read William Gibson's Neuromancer, or if you want something smaller, his short story, "Burning Chrome," and see if it's still relevant for you and your ideas.
