An Overview Of Aircraft Hacking --Part One.

Known methods of hacking aircraft and looking at unauthorized threats related to the goals of destroying or interfering with communications systems and full control of aircraft, here is a comprehensive discussion of the details of possible attacks and some important points.

First, the vulnerabilities of aircraft communication systems:
The Aircraft Communications Addressing and Reporting System (ACARS), a system that transmits digital data communications between ground stations and the aircraft, is a limited collector that can intercept or alter messages completely by attackers, although a number of unique technological advances have been made Turn to prevent and keep security at the highest level.

Communications from ground stations to aircraft are transmitted through HF & VHF ground controllers or satellites. These messages can range from the start of the flight to the flight statuses to the repair attempt stages.
ACARS does not have the ability to collect strong HF and VHF transmissions, which has prevented some areas from using strong protocol systems, but it is possible that older aircraft and ground stations can still use unencrypted communications, which is a facilitator For attackers to forge potential 'ACARS' deposits Send misleading information to the flight crew and cause problems with data editing, uploading or repairing the latest changes.

There is another point, ADS-B, which works based on GPS and broadcasts the position, altitude and speed of aircraft individually, which is unencrypted and very publicly available, and the purpose is to improve situational awareness from aircraft to ground controllers Attackers can use cheap SDRs To inject and stop 'ADS-B' that can create unknown aircraft or create unnoticed flight paths and change the course of the aircraft, which causes confusion and traffic in the skies and approaching collisions, and to further protect and prevent aircraft from disappearing A modification has been made to the ADS-B systems to make them self-discoverable Radars and their own signaling.

We also have CPDLC, whose older protocols do not use encryption, which again allows attackers to access messages with their sophisticated devices. That can mislead a pilot by injecting malicious messages and these are in modern ones like 'NEXTGEN' &'FAA' that store transactions and encrypt all messages in a more secure way.

We will discuss some other related issues in the coming days.
