Quest Diagnostics has confirmed a cyberattack affecting Quanum, its platform for ordering laboratory tests and managing billing. According to TechCrunch, the company said in a filing with the SEC, the US securities regulator, that it learned of the attack on Wednesday. This statement does not specify when the intrusion began.
Quanum stores health records as well as diagnostic and billing information. Quest says the unauthorized access affected certain patient records. In its security notice, the company also acknowledges that personal information and records were taken. It is still investigating the precise categories of data involved and says it has notified law enforcement.
The scale of the incident remains undetermined. Quest has disclosed neither the number of patients affected nor the number of client organizations involved. The company has also not said whether a hacking group contacted it with financial demands.
The distinction between Quanum’s functions and the scope of the actual compromise is essential to assessing this breach. The fact that the platform processes medical and administrative data does not establish that all these categories were stolen for every patient. Further details from the investigation are still needed to characterize the actual exposure.
