Hundreds of thousands of people are receiving letters notifying them that their medical records were stolen in a cyberattack at U.S. health tech giant CareCloud earlier this year, as new details about the data breach come to light.<\/p>\n
The company has said little about the breach since March, when it first admitted that hackers had raided one of its six stores of patient data<\/a>. New disclosures seen by TechCrunch offer the clearest picture of the breach so far, including that nearly 350,000 people have been affected so far.<\/p>\n The New Jersey-based CareCloud stores patient records for more than 45,000 providers across the U.S., including doctors\u2019 offices, hospitals, and other medical practices. As such, the company handles a large amount of sensitive medical and billing data on millions of healthcare patients across the country.<\/p>\n According to a data breach notice filed<\/a> with California\u2019s attorney general\u2019s office this week, CareCloud said hackers had access to one of its electronic health record data stores for at least six days, between March 10 and March 16. The company said a hacker \u201cclaimed to have exfiltrated data from databases.\u201d The company did not say how the hackers made the claim, but it\u2019s not uncommon for hackers to share samples of stolen data with victims alongside a ransom demand to prevent it from being published online.<\/p>\n TechCrunch is unaware of any ransomware or extortion group publicly taking credit for the data breach at CareCloud.<\/p>\n The notice said little about the hack beyond its initial March 27 disclosure<\/a> to regulators, but confirmed TechCrunch\u2019s earlier report that the hackers broke into the company\u2019s data storage hosted on Amazon Web Services.<\/p>\n TechCrunch has learned that the data breach affects at least 345,000 people across the United States, according to listings with several attorneys general, including those in New Hampshire, Massachusetts, and Texas. TechCrunch has also obtained CareCloud\u2019s disclosure filed with Maine\u2019s attorney general.\u00a0<\/p>\n The number of affected people is likely to rise as more disclosures are filed with state authorities.\u00a0<\/p>\n The notices confirm that CareCloud notified authorities that the stolen data included people\u2019s names, postal addresses, and Social Security numbers, as well as government-issued identification numbers, such as passports and driver\u2019s licenses. The notices also say that the stolen data included financial information, such as bank account information and payment card numbers, alongside a wealth of medical and health-related information.<\/p>\n CareCloud chief executive Stephen Snyder did not respond to TechCrunch\u2019s request for comment or to questions about the incident.<\/p>\n The cyberattack targeting CareCloud is the latest in a series of breaches targeting healthcare providers this year, including one at healthcare revenue tech giant TriZetto that affected 3.4 million people<\/a>, and a month-long breach at New York\u2019s public health provider NYC Health + Hospitals, in which hackers stole 1.8 million people\u2019s health data<\/a> and thousands of employees\u2019 fingerprint scans.<\/p>\n Last week, U.K.-based tech provider Craneware, which provides accounting and billing software to thousands of U.S. healthcare providers, confirmed hackers stole a \u201csignificant volume\u201d of its customers\u2019 data<\/a> from its servers, raising concerns about a breach involving patient data.<\/p>\n Do you know more about CareCloud\u2019s data breach?
