Medical device vulnerability could let hackers steal Wi-Fi credentials

A vulnerability found in an interaction between a Wi-Fi-enabled battery system and an infusion pump for the delivery of medication could provide bad actors with a method for stealing access to Wi-Fi networks used by healthcare organizations, according to Boston-based security firm Rapid7.

The most serious issue involves Baxter International’s SIGMA Spectrum infusion pump and its associated Wi-Fi battery system, Rapid7 reported this week. The attack requires physical access to the infusion pump. The root of the problem is that the Spectrum battery units store Wi-Fi credential information on the device in non-volatile memory, which means that a bad actor could simply purchase a battery unit, connect it to the infusion pump, and quicky turn it on and off again to force the infusion pump to write Wi-Fi credentials to the battery’s memory.
