Broadband inversion
Broadband inversion was a method of blocking subspace communication and short-range sensors. However, as a broadband approach, it made a nonsense of the equipment of all ships in range of the attack — even the one that issued it. 

Thus, when the T'Lani and Kellerun's joint attack force issued such an attack upon Benjamin Sisko's runabout in 2370, their ship was made to fly blind, as well. ()
