Personally, I'd suggest going the other route. Get the best Commlink you can afford (DR 6 at CharGen) and plug in the best Stealth Dongle you can afford. Then mod for an Attack rating of 1. You could potentially start with Attack 1, Sleaze 6, Data Process 6, Firewall 6.
Sleaze is a far better stat to have, especially if you're just a backup hacker for the TM. Sleaze is what helps you avoid detection, if you're Running Silent and someone is trying to find you with Matrix Perception. Sleaze actions, if successful, go completely unnoticed. Even if you succeed at an Attack action, the target knows they're under attack. And if you fail an Attack action, you end up inflicting Matrix damage back onto yourself.
