First off, don't be that guy and try to play this guy. It's supremely uncool to your GM. I built this to prove a point about it being possible. But playing this guy would make your GM pull their hair out.

Non-hacking stuff first; the character's knowledge skills and contacts were just picked off-handedly, as they don't matter for the build and aren't important to the mechanic concept. In a fight, this character would rely on their Doberman or a smart firing platform with a shotgun on it, fired via Gunnery. Their physical initiative (12+2d6) isn't bad if they absolutely cannot afford to be in VR, but most of their best work will be done there. In these situations, both the drone and the firing platform help protect them.
But the main concept of this build is their ability to break the Matrix by being untargetable.
In the matrix, in order to target someone, you must be able to see their icon (whether it's a Persona, Device, or File). Running Silent means that they must beat your LOG + Sleaze with Computer + Intuition (or Rating x 2 for Patrol IC). This character's dice pool for this roll is so incredibly high that they are almost impossible to spot, and thus, can do things with impunity as matrix opponents won't be able to attack them.
Logic is maxed out with Genetic Optimization (LOG) and using the Restricted Gear quality to buy a R3 Cerebral Booster. Not only does this help this build's specific goal (be untargetable) but it just makes them great at hacking in general. Not buying Exceptional Attribute means we have space to buy other important qualities, but I'll go into that later.
Now with Sleaze. The deck I purchased has 7 as its highest (and 1 as its lowest, ouch!). We use the Overclocker quality to make that 8, then Stealth to make it 9, then Smoke-and-Mirrors to make it 14. For this build I'll go with the modification that removes two boxes from its condition monitor. That's 15 Sleaze, which is just ballin'. Really and truly. The Noise caused by Smoke-and-Mirrors is countered by Signal Scrubber, your Datajack, and plugging in the Vectored Signal Filter.
Finally we have the Data Anomaly quality and Fade to Black. Together, this means that this character has a 27 dice to resist being spotted via Matrix Perception, and may make a free Hide action whenever they remove all the marks from them with Erase Mark.
27 dice is, on average, 9 hits. It's also significantly higher than what most NPCs would be capable of with Computer + Intuition or even Host Rating x 2. When you factor in device limits, the chances of finding this character are lowered even more, as limits will stop NPCs from being able to even reach the same number of hits you roll on average. You're literally so deeply hidden in the matrix, that someone with a Transys Avalon could not find you without burning Edge. Their device is simply too basic to weak to find your icon. You are able to use the Buying Hits rule (if your GM allows it) to buy 6 hits-- Meaning anything with a limit of 6 can never spot you (you're the defender on the roll-- Ties go to the defender.) That security rigger with his expensive and rare Lone Star *Remote Commander* RCC? He may as well be using scratch-built junk for all the good it will be doing him in trying to spot your icon.
With this, you're actually better off relying on Attack actions (like Brute Force) over Sleaze Actions (like Hack on the Fly). Why? Because you're more likely to fail a Hack on the Fly roll (16 dice) than for them to beat your Running Silent defense pool (again, 27). If you fail a Sleaze action, your target immediately gains a mark on you, and thus gets around having to manually spot you. A failed Attack action causes damage (usually only 1 or 2) but you can afford to fail multiple times. "But Firebug!" you say, trying not to let it show show that you have a huge crush on me, "Attack actions alert the target if you succeed! Aren't you trying to be stealthy?"
You're not wrong. But Attack actions only tell them they should start rolling Matrix Perception, which we know they will probably never succeed (and if they do, you can quick make a Hide action). It's better to always have them looking (and have basically no chance of finding you) and occasionally you take some chip damage, than to have them looking around because weird stuff is happening and occasionally they get a mark on you and try to dump your ass ASAP.
This character is an interesting experiment, but again, I don't recommend playing this guy (or someone like them). Being untouchable just makes parts of the game boring and frustrates your GM.
