Quest Diagnostics reports cyberattack that may have exposed patient records

Quest Diagnostics disclosed in an SEC filing that its Quanum LSM system was accessed without authorization on Oct 21, potentially compromising patient data.

The breach affected a system used by certain clients to order tests and view results, and the company believes an unauthorized party accessed some patient records, though the number of records is unknown.

Quest has engaged external cybersecurity experts and notified federal law enforcement, stating the incident has not materially disrupted its operations or ability to serve patients.

The attack adds Quest to a growing list of medtech firms hit by cyber incidents this year, including Novocure, Boston Scientific, Medtronic, Stryker, Abbott and iRhythm.
