Imagine the following Scenario:
A technomancer with Signal 5 has all of his devices, all with Signal 1, slaved to his Living Persona, for security. A Hacker, also with Signal 5, about a kilometer away wants to Hack the TM's PAN. Is this possible? Can he roll Exploit + Hacking, fake the commcode of someone that the TM's Persona is Subscribed to, and start Spoofing commands to the devices in the PAN? Would the TM notice packets moving through her that are stealing info or making her devices act awry? Without a good Sniffer Complex Form, is it all just the ebb and flow of the Matrix?

I read it 3 times just to make sure I'm reading you right.. but how would hacking somone else's commcode give you access to the Technomancer's PAN?
It's like saying that since Joe Wageslave is subscribed to Cheesy Pizza, I can now hack their network...

You'd have to hack the items directly in my opinion, as the Technomancer does not have a commcode, so you have no direct connection to their signal.

no but if cheesy pizza is subscribed to joe...

how can a technomancer use a skinlink without having to use a normal commlink? they can't exactly add accessories to their brain without losing resonance.

It's an often used houserule.

It just feels right, if a technomancer can hack with laying on hands .

Yeah, TMs having an organic skinlink in addition to an organic commlink was an automatic houserule in our game.

The Technomancer that I play has all of his devices skinlinked, but he's got drones and whatnot, they're obviously not skinlinked, but they are actively subscribed to the Living Persona, and I gave them a short signal rating to avoid Hackers concealed in a building nearby or something. But I'm wondering how much of the organic commlink's processes are automated. If the enemy Hacker sends a spoofed packet to one of the drones through the organic commlink, is it apparent to the TM that someone nearby just sent a packet to one of the drones? Does he actually know about and process the packet consciously or is it all just the Resonance of the Matrix?

i would guess its kinda like a reflex that he can partialy control.

kinda like how you can, with training and consentration, control the beating of your heart. but if left alone, it will beat as needed for whatever state the body is in at the moment.

assuming you don't use the automatic skinlink, then the TM can use a set of trodes with a skinlink to interact with devices on his person, no commlink required.

oh, and i don't think you can hack a technomancer, but you could certainly spoof his devices.

there might be a problem with that if the techno is trying to hack his own stuff, yes.

trodes give you a DNI link to whatever they are attached to on the other end. i find it hard to believe that the DNI wouldn't let you operate your personal devices through it.
