The health-care giant claimed no "clinical" information was breached by the hackers, a claim undercut by sample data provided to an industry analyst.

Hackers stole another half a million people’s personal and health information during a ransomware attack on a technology vendor earlier this year.

Intellihartx, a Tennessee-based company that handles patient payment balances and collections, said in a notice filed with the Maine attorney general’s office that 489,830 patients had information stolen in the cyberattack targeting its vendor, Fortra.

Enzo Biochem says the clinical test information of roughly 2.47 million individuals was exposed in a recent ransomware attack.
