Hacker claims to have stolen 10 million patient records and is selling them on the black market. The records come from healthcare providers across the U.S. and are being sold in batches for up to $134,000. The hacker is trying to extort the providers by telling them their patient data won’t be sold if they pay a ransom. At least one of the healthcare providers so far has refused to give in, TheDarkOverlord said in an interview Friday. Security firm InfoArmor has been investigating the breaches and says the stolen data is real.”]
