It has been a particularly bad six months for the healthcare industry. Data breaches have been reported in record numbers and the number of healthcare records exposed on a daily basis is extremely concerning. The trend of more than one healthcare data breach a day has continued throughout 2019, even reaching a rate of 2 per day in May.
According to the 2019 Mid-Year Data Breach Barometer Report from Protenus and Databreaches.net, 31,611,235 healthcare records were breached between January 2019 and June 2019. To put that figure into perspective, it is double the number of records exposed in healthcare data breaches in the entirety of 2018 (14,217,811 records).
One breach stands out from the 285 incidents reported in the first half of the year: The data breach at American Medical Collection Agency (AMCA). A batch of stolen credentials on a dark net marketplace was traced back to AMCA, which discovered its payment web page had been compromised for months. It is not yet known exactly how many healthcare records were exposed in the incident, but 18 clients are known to have been affected and more than 20 million records have been confirmed as having been breached.
The report shows the first 6 months was dominated by hacking incidents, which accounted for 60% of all incidents and 88% of breached records. 168 data breaches were due to hacking, 88 involved phishing, 27 involved ransomware or malware, and one involved another form of extortion.
20.91% of all breaches – 60 incidents – were insider breaches. 3,457,621 records were exposed in those breaches or 11% of all breached records. 35% of incidents were classified as being caused by insider error and 22% were due to insider wrongdoing. There were 24 theft incidents were reported involving at least 184,932 records and the cause of 32 incidents (142,009 records) is unknown.
Healthcare providers reported 72% of breaches, 11% were reported by health plans, and 9% were reported by business associates. 8% of breaches could not be classified. While the above distribution of breaches is not atypical, 2019 has been a particularly bad year for business associates.
In three of the first six months of 2019 a business associate reported the largest breach of the month. The largest breach of the year was at a business associate. That breach is already the second largest healthcare data breach of all time. Hacking was the biggest problem area for business associates. 45% of business associate data breaches were due to hacking and other IT incidents.
One business associate, Dominion National, took 8.5 years to discover its systems had been breached. By the time the breach was discovered, the records of 2,964,778 individuals had been compromised. Overall the average time to discover a breach was 50 days. The average time to report a breach to the HHS was 77 days and the median reporting time was 60 days.
“In order for healthcare organizations to reduce risk across their organization and to truly combat the challenges associated with health data security, it is critical for healthcare privacy offices to utilize healthcare compliance analytics that will allow them to audit every access to their patient data,” wrote Protenus. “Full visibility into how their data is being accessed will help healthcare organizations prevent data breaches from wreaking havoc on their organization and the patients who trust them with their personal information.”
