commjacking noun [U] UK /ˈkɒm.dʒæk.ɪŋ/ US /ˈkɑːm.dʒæk.ɪŋ/
a method of intercepting the data flow on a wifi network
This notion of commjacking was invented to describe the ability to hijack the communication channel between any device and the WiFi or cellular networks to which it is connected. Commjacking gives the attacker the ability to eavesdrop on conversations, intercept data transmissions to and from the device, and manipulate the data, or the device itself.
