Well, it's been mentioned in pretty much every article or video I've seen so far, but if you insist:

Sure hacking is theoretically possible, but the transmit/receive radius is approximately 100 meters and each device can only be paired with one other device (if something comes unpaired, the whole system needs to be re-paired). Combined with 128-bit AES encryption, FHSS, and hopefully the lack of will by hackers, SRAM is not concerned about a lack of security in the slightest.
