We urge patients to stay on the product,' Levy said. 'We believe the OneTouch Ping system is safe and reliable. He said such attacks are difficult to pull off because they require specialised technical expertise and sophisticated equipment. J&J executives said they worked on the security issues with Radcliffe.ĭosing a patient with too much insulin could cause hypoglycaemia, or low blood sugar, which in extreme cases can be life-threatening, said Brian Levy, chief medical officer with J&J's diabetes unit.Ĭompany technicians were able to replicate Radcliffe's findings, confirming that a hacker could order the pump to dose insulin from a distance of up to eight metres, Levy said. The system is vulnerable because those communications are not encrypted, or scrambled, to prevent hackers from gaining access to the device, said Radcliffe, who reported vulnerabilities in the pump to J&J in April and published them on the Rapid7 blog on Tuesday. Jay Radcliffe, a diabetic and researcher with cyber security firm Rapid7, said he had identified ways for a hacker to spoof communications between the remote control and the OneTouch Ping insulin pump, potentially forcing it to deliver unauthorised insulin injections. The Animas OneTouch Ping, which was launched in 2008, is sold with a wireless remote control that patients can use to order the pump to dose insulin so that they do not need access to the device itself, which is typically worn under clothing and can be awkward to reach. Insulin pumps are medical devices that patients attach to their bodies that injects insulin through catheters. 'It would require technical expertise, sophisticated equipment and proximity to the pump, as the OneTouch Ping system is not connected to the Internet or to any external network.'Ī copy of the text of the letter was made available to Reuters. 'The probability of unauthorised access to the OneTouch Ping system is extremely low,' the company said in letters sent on Monday to doctors and about 114 000 patients who use the device in the US and Canada.

The company is nonetheless warning customers and providing advice on how to fix the problem. J&J executives told Reuters they knew of no examples of attempted hacking attacks on the device, the J&J Animas OneTouch Ping insulin pump. Medical device experts said they believe it was the first time a manufacturer had issued such a warning to patients about a cyber vulnerability, a hot topic in the industry following revelations last month about possible bugs in pacemakers and defibrillators. Johnson & Johnson is telling patients that it has learned of a security vulnerability in one of its insulin pumps that a hacker could exploit to overdose diabetic patients with insulin, though it describes the risk as low. Patients can take several steps to thwart potential attacks on the Animas OneTouch Ping insulin pump, says J&J.
