Stryker, a Michigan-based medical device company, has been hit by a cyberattack attributed to Iranian hackers. The company is one of the largest makers of hospital beds and other health care-related furniture. A survey of local medical providers found that while all use Stryker products, none have detected any suspicious activity since the attack started. However, there have been no reports that the attack has spread from Strykers' internal networks to those of hospitals that use its products. The cyberattack has led to increased scrutiny on cyberattacks, costing hospitals hundreds of millions per year in lost productivity, legal settlements and poor publicity.
