“EASY CYBER ATTACK AGAINST NEW BENTLEY - CRITICAL ISSUE IT IS INCREDIBLY DANGEROUS TO CONNECT THIS CAR TO THE INTERNET USING A SIM CARD, AS THE CAR IS LITTERED WITH HIGH IMPACT VULNERABILITIES THAT CAN EASILY BE EXPLOITED TO SHUT DOWN SYSTEMS, THIS WOULD DENY SERVICE OF SYSTEMS, LIKE STEERING OR BRAKES, OR AIRBAGS. THERE ARE NEARLY 100 CONNECTED DEVICES IN THE CAR THAT IS CENTRALLY MANAGED USING ONE COMPUTER SYSTEMS THAT IS VERY VULNERABLE. THIS IS A FUNDAMENTAL PROBLEM AT BENTLEY HQ, AS ONE OF THE VULNERABILITIES WAS FIRST IDENTIFIED IN 1999, IT WAS PATCHED IN 1999 AND YET A 2017 CAR STILL HAS THE VULNERABILITY WITHOUT ANY PATCH. THIS MEANS NOT ONLY IS THIS CAR EXTREMELY VULNERABLE TO CYBER ATTACK BUT THE PROCESS TO DESIGN THE SOFTWARE IN THE FACTORY HAD LITTLE TO NO REGARD TO CUSTOMER SECURITY. IT IS POSSIBLE TO ELECTRONICALLY SWEEP ALL IP'S IN THE USA SEARCHING FOR BENTLEY BENTAGYA'S AND THEN CONSTRUCT A CYBER ATTACK AT ALL VEHICLES SIMULTANEOUSLY. THIS IS A VERY VERY SERIOUS ISSUE. I NOTIFIED BENTLEY AND PROVIDED THE FULL CYBER ASSESSMENT REPORT AND HAD NOT REPLY WHATSOEVER. THEY SHOULD IMMEDIATELY HAVE EVERY CUSTOMER REMOVE THE SIM CARD (THIS SHOULD BE A…”
“BENTLEY LANE ASSIST - MAJOR ISSUE THE BENTLEY LANE ASSIST IS SUPPOSED TO KEEP YOU IN A LANE, HOWEVER TWICE NOW I HAVE BEEN TRAVELLING ON A TWO WAY ROAD AND IT HAS TAKEN ME WITH A VIOLENT STEERING MANOEUVRE INTO ONCOMING TRAFFIC. THE ISSUE IS THAT WHEN YOU ARE IN A TWO LANE ROAD AND THE ROAD MARKINGS IN THE CENTRE LINE SPREAD APART FOR A LEFT TURN AREA, THE CAR WILL OFTEN FOLLOW THE OUTSIDE LINE INSTEAD OF THE INSIDE LINE, THAT LINE TAKING YOU INTO ONCOMING TRAFFIC. YOU THEN NEED TO VIOLENTLY YANK THE STEERING TO CORRECT HE LANE ASSIST. I TOOK THE VEHICLE IMMEDIATELY TO BENTLEY AFTER THE SECOND OCCASION AND THEY FAILED AGAIN TO FIND THE FAULT. THEY ASKED ME IF I COULD VIDEO IT HAPPENING - BUT THAT SEEMS TO MAKE A DANGEROUS SITUATION MORE DANGEROUS AND I DON'T KNOW WHEN IT IS GOING TO HAPPEN. THIS IS THE PROBLEM WITH SELF DRIVING CARS THAT ARE DESIGNED BADLY, IT MAKES YOU INCREDIBLY NERVOUS TO DRIVE AS YOU NEVER KNOW WHAT THE CAR IS GOING TO DO.”
