Russian ransomware gang BlackCat, also known as ALPHV, has claimed that it has stolen 7TB of data from Barts Health National Health Service (NHS) Trust.
The claim comes from the gang itself, which posted news on the cyber attack on its dark web data leaks site. The post was made on June 30, with the gang calling it the “most bigger leak [sic] from health care system in UK”.
BlackCat went on to threaten Barts Trust, saying that the organization had three days make contact with the gang regarding the cyber attack and data theft. If the Trust chose not to contact them, the gang said they would start publishing the data online, which allegedly mostly contains “citizens confidential documents”.
