Are you talking about realistic hacking, or cyberpunk-style hacking?

For CP I think you have all the mechanics you need. It would be a very good deck indeed. I don't remember the current hacking rules, but it stands to reason that higher-TL, higher-Complexity versions of hacking software should have improved skill or other bonuses.

For realistic hacking, the only thing a powerful computer is inherently good at on a present-day network with present-day software is decryption - but let's go gonzo and say that the computer includes incredibly advanced software that integrates network mapping with historical data and current events to actually predict which systems might be vulnerable to any one of hundreds of known exploits, then attempts to exploit them.

Let's go further and assume that it performs data mining operations in order to improve its predictive performance.

Let's suppose that as soon as it starts getting some system access, it uses its data to target specific users with phishing attacks while installing software on any open computers so it can use them for additional processing power, DDOS attacks, or to disseminate misinformation or conceal the origin of further attacks.

In short, it wouldn't do anything a skilled hacker couldn't do now - but it would do it on a much broader scale, as if hundreds of skilled hackers working together set out to divide and hack the entire internet piece by piece.

That's really about as far as we should probably go without a bigger computer and a volitional AI; we've probably already exceeded the boundaries of reasonable software design. But the next phase, if there was one, would be to infiltrate personal accounts, official records, social media, etc. to further some sinister purpose: propaganda, say, or predictable market manipulations that the user could take advantage of, or influencing the development of certain technologies, or definitely getting redundant copies of itself hosted on compatible hardware in case of discovery...
