Blood-testing lab LabCorp grapples with data breach: 5 things to know

LabCorp, a medical diagnostics company in Burlington, N.C., detected "suspicious activities" on its computer network over the July 14 weekend that may have compromised the health records of millions of patients, Fortune reports.

Here are five things to know:

1. In a filing with the Securities and Exchange Commission, LabCorp said it "immediately took certain systems offline as part of its comprehensive response to contain the activity," according to Fortune. The company has not yet uncovered any evidence its data had been transferred or misused, but the investigation is ongoing.

2. "This temporarily affected test processing and customer access to test results on or over the weekend," the company said, according to Fortune. "Work has been ongoing to restore full system functionality as quickly as possible. Testing operations have substantially resumed today, and we anticipate that additional systems and functions will be restored through the next several days. Some customers of LabCorp Diagnostics may experience brief delays in receiving results as we complete that process."

3. LabCorp offers diagnostic, drug development and technology solutions for more than 115 million patients annually, its website states, according to InfoSecurity Magazine. The company processes tests on more than 2.5 million patient specimens weekly and supports clinical trials in about 100 countries.

4. The incident only affected LabCorp Diagnostics systems, and "there was no indication that it affected systems used by Covance Drug Development." LabCorp would not say whether the breach was ransomware-related.

5. Healthcare is one of the most frequently cyberattacked industries, and it also incurs the highest breach-related costs.
