Raven (2020)

Raven is anti-IC program  attacks the Recognition function of a program (standard anti-program roll), and if it is successful, the program will no longer notice "intruders" if defending a system. It also cannot recognize locations or specific 'runners, so it cannot be sent to "find" a place or person. The program is otherwise functional. This is usable on such programs as the Dog series (Watchdog, Bloodhound, etc) along with those that rely on Recognition or Pseudo-Intellect (Firestarter, Hellhound, Thug, etc).
