Dead Siccing
Avoid your enemies sleuthing.

Dead siccing: Use a recently dead corpse by plugging into their sic chip somehow. Maybe even make it a device the interfaces with them after they're ripped out.

Allow them to submit a number of sic messages through that chip(Depending on skill)

This allows for a number of things but these two I like the most and they basically boil down to the same thing.

Framing someone to make it actually look like they did it.

Making a pubsic post that's tied to that corpses Sic ID.

Even if this isn't viable it's still a cool idea that drives home the grittiness of cyberpunk.
