A group of hackers is continuing its extortion campaign against US medical centers and organizations. Peachtree Orthopaedic Clinic, based in Atlanta, Georgia, announced the theft of names, dates of birth, addresses, prescription records and social security numbers back in October.
Over a month later, the hackers behind the attack, The Dark Overlord, are seemingly annoyed that they have not received their demanded ransom payment, and are threatening to release the alleged personal information of several high profile sports stars.
The CEO of the clinic allegedly "fooled us and made us believe he was going to pay us 83 BTC ($60,500)," someone from The Dark Overlord told Motherboard in an online chat. They claimed to have stolen 543,000 records in all.
The group has attempted to extort several medical organizations this year. In general, The Dark Overlord hacks a target, steals its data, and then demands payment in exchange for not releasing the data publicly.
In some cases, The Dark Overlord has gone on to list data on the dark web in order to intimidate the victims further. Even approaching the media with details on each hack is part of a calculated attempt to pressure affected organizations into paying up.
According to the group, the hacked Peachtree data includes records on a number of sports stars. These individuals, who Motherboard has decided not to publicly name, did not respond to a request for comment.
The Dark Overlord indicated they planned to release the alleged records of a handful of these athletes.
"We will continue to release more sensitive medical records until our demands are met," the group writes in an as-of-yet unreleased announcement.
"Michael Butler, CEO of Peachtree Orthopedics, explained to us on Wednesday, 21st of September that his insurance would be able to provide an 83 BTC ($60,500) down-payment towards our demand. As we have not received this promised down-payment we will be gradually following through with each and every threat made," the announcement adds.
A representative from Peachtree would not talk on the record about the incident, but provided Motherboard with the clinic's previous statement.
"Patient care is at the center of our mission and we take seriously the confidentiality of the information we hold. Our investigation is in its early stages, but we felt it was important to communicate what we know at this time," Butler said in the statement.
"We regret any anxiety or frustration that this causes our patients and are committed to supporting them," he continued. Local media reports from the time of the original announcement said that some affected patients had received letters from Peachtree.
An active FBI investigation is underway into the incident.
