wiretappers
Covert line monitors
Wiretappers are people who secretly monitor communications—originally by tapping into telephone wires, now by intercepting any electronic transmission.
The term applies to law enforcement conducting surveillance, intelligence agents gathering information, or criminals eavesdropping illegally: The wiretappers recorded months of conversations between the suspects.
