Patient monitoring systems can now be hacked to alter vital signs

A vulnerability in the RWHAT networking protocol for Internet of Things (IoT) devices could allow hackers to falsify a patient's vital signs on their hospital bedside monitor in under five seconds, according to new research from McAfee's Advanced Threat Research team.

The research, detailed in a Saturday blog post, noted that the attack could be used to cause physical harm to the patient.

Dr. Shaun Nordeck, quoted in the post, said that vital signs are "integral to clinical decision making." Often, those signs are used to make quick decisions about a patient's care and, if incorrect, could have dire consequences.
