Why post it to me? You do know that the exploit being discussed above has nothing to do with a remote starter as they don't use an RFID challenge/response signaling system, don't you? To clone a remote starter remote control signal you would have to be scanning/reading the code while the button is repeatedly pressed a number of times till the scanner could figure out the algorithm used for the code hopping. They don't transmit when the receive a challenge signal. If you want to be paranoid about the article mentioned above, then the way to protect oneself is to have their stock Honda (or any other brand) key stored in a lead lined key case when walking around with it in their pocket. The car alarm, remote starter, keyless entry unit, to be cloned would require first getting your hands on the actual FOB, in which case you don't need to clone it as you have the original. All that aside, I'm guessing the "post that to seth on the "Honda Pilot EXL 2007 - remote start" thread from july 14." was more an attempt at being obnoxious than anything else. I know I never said the system was invulnerable, just not a high-risk threat. Having one's head or house destroyed by a piece of falling debris is also possible, but again, not likely and therefore I'm not losing any sleep worrying about it. Coincidently, neither my home owners insurance, car insurance or life insurance has any clause excluding space debris or remote starters. If they thought it was a high risk possibility you better believe they would have a clause and an additional cost rider as a result to make more money off the customer. |
