WASHINGTON (Reuters) - In a message posted to, and then quickly deleted from their darknet site, the hackers blamed for striking the UnitedHealth Group said on Wednesday they stole millions of sensitive records, including medical insurance and health data, from the company.
In its claim of responsibility, the group known as "Blackcat" or "ALPHV" posted a statement to its site saying it had stolen 8 terabytes of data from UnitedHealth, according to screenshots of the posting shared online by cybersecurity researchers.
