The US homeland security department has found two loopholes in 16 different models of Medtronic implantable defibrillators that could make it vulnerable to cyber attacks. The Homeland Security Department has issued an alert on this matter.
Nearly 750,000 heart devices made by Medtronic contain vulnerabilities, which could let a cyber attacker with sophisticated insider knowledge harm a patient by altering programming on an implanted defibrillator, Star Tribune reported on Friday.
The first vulnerability could allow improper access to data exchanged between a defibrillator and an external device, like an at-home monitor.
The Homeland Security Department oversees security in the critical US infrastructure, including medical devices.
"Medtronic is now monitoring its network for signs that someone was trying to exploit the vulnerabilities," said the report.
The vulnerabilities do not affect Medtronic pacemakers, the report added.
Implantable defibrillators are battery-run computers implanted in patients' upper chests to monitor heart and send electric pulses or high-voltage shocks to prevent sudden cardiac death and treat abnormal heartbeats.
"To date, no cyber attack, privacy breach, or patient harm has been observed or associated with these issues," a company spokesperson was quoted as saying in a CNET report.
