Medical device manufacturer Animas on Tuesday warned that its OneTouch Ping insulin pump system was susceptible to hacking. "We have been notified of a cybersecurity issue with the OneTouch Ping, specifically that a person could potentially gain unauthorized access to the pump through its unencrypted radio frequency communication system," reads the company's letter to users of the device. The probability of anyone accessing the pump without authorization was "extremely low," the letter notes. Animas is owned by Johnson & Johnson.
