Achieving "Hack the Planet" (Watch Dogs: Legion)

Actually you need to crack at once 8 devices, I know that you need a character with the ability to "virus" (or something like that, do not remember the name, in general, spreads hacking), but I somehow did not really understand how it works, and that it is to crack that the character's property worked ... When I tried to pull out the drone, distract, it is still only 1 Persian/drone reacted, and I did not understand what to do ... Are there any tips?) I'll be grateful.
