Boeing 757 Hacked in DHS Test
Researchers did not need a person on board to gain greater access to the aircraft.

A team of government researchers successfully accessed the systems of a Boeing 757 in a non-laboratory environment in 2016, a Department of Homeland Security (DHS) cybersecurity official claimed late last year at the 2017 CyberSat Summit in Tysons Corner, Virginia. However, the result of this test likely do not pose a major risk to airlines at this time due to the expertise required, researchers concluded.
