Summary Box: Pump maker IDed after hacking talk

THE HACKING: Jay Radcliffe, a diabetic who experimented on his own medical equipment, had found serious security holes in a popular type of insulin pump that diabetics wear. It allows people to program a special remote control to command strangers’ pumps to dispense the wrong dosage of insulin.

WHAT WASN’T SAID: At the time, he wouldn’t identify the pump maker’s name, preferring to work with the company first to fix it. He’s changing his mind after he says the company ignored him.

COMPANY RESPONSE: Medtronic Inc. would not directly address its interactions with Radcliffe, but it says it’s reviewing the research.
