China flight systems jammed by pig farm’s African swine fever defences (scmp)
"Chinese state media reported last week that gangs were exploiting the African swine fever crisis by deliberately spreading the disease by using drones to drop infected items on to pig farms. A Chinese pig farm’s attempt to ward off drones – said to be spreading African swine fever – jammed the navigation systems of a number of planes flying overhead. In more common cases, according to the magazine, the criminals spread rumours about the presence of the virus to achieve a cheap purchase price."
