LifeBridge Health has notified 500,000 patients that their personal information may have been exposed in a cyber attack recently discovered by the health system.
Indication of an attack was first detected in March and an investigation by a national forsenic firm hired by the hospital determined that the data breach took place Sept. 27, 2016. The health system notified patients by letter last week.
The attacker accessed the health system’s servers through one of its physician practices, LifeBridge Potomac Professionals. Information potentially taken included names, addresses, birth dates, insurance information, and Social Security numbers found in the patient registration and billing system.
LifeBridge has offered credit monitoring to any patients whose Social Security numbers were breached, but said it doesn’t believe anyone’s information was misused.
LifeBridge is the latest health system to have its patient data accessed. Experts have said the growing use of electronic medical records may make health systems and hospitals more vulnerable to these attacks.
CareFirst BlueCross BlueShield was the victim of a phishing email attack in March that could have exposed the personal information of 6,800 of the insurer’s members. An employee’s account was used to send emails to people not associated with CareFirst.
The personal information that could have been compromised includes names, member identification numbers and dates of birth. In eight cases, Social Security numbers could have been taken. No medical or financial information was compromised.
In 2016, unidentified hackers encrypted data at MedStar Health hospitals in Maryland and the District of Columbia. The hackers demanded bitcoin payments in exchange for the digital keys to unlock the encrypted data.
In March, Under Armour announced that 150 million users of its MyFitnessPal food and nutrition app and website were affected by a breach.
