December’s most notable healthcare breaches:

 LA Health Department

The Los Angeles Health Department suffered the largest data breach in December. It is estimated a phishing email sent to employees compromised over 700,000 personal records. Phishing emails contain viruses which allow access to protected information. These emails usually have an open rate around 30%, but in this case, the open rate was only about 10%. However, even with the relatively small number of opens, a significant amount of damage was still caused to the server. The data compromised consisted of names, dates of birth, social security numbers, payment/bank account information, social security numbers, and medical diagnoses.

Ransomware

A health center also based in California was the victim of a ransomware attack. Troldesh, which is the ransomware that was used in this attack works by conducting scans and encrypting files making them inaccessible to authorized users. Toldesh was installed by an unauthorized user who logged into the server. Names, medical diagnoses, medical record numbers, and insurance numbers were among the information stolen. Luckily, no financial information or social security numbers were compromised.

Lab

Earlier this month, a medical laboratory company based out of New Jersey disclosed a data breach that affected more than 34,000 people. Information stolen included personal information such as names, phone numbers, dates of birth and lab results. The information was stolen through MyQuest, which is a mobile app that allows patients to share medical records. The app was improperly secured allowing the hackers to gain access to personal records.
