The Keralty multinational healthcare organization suffered a RansomHouse ransomware attack on Sunday, disrupting the websites and operations of the company and its subsidiaries.
"The computer servers of the Keralty Group companies have been the object of a cyberattack, which has generated technical failures in our systems," reads a translated statement from Keralty.
BleepingComputer has attempted to contact the Keralty Group with questions about the attack but has not received a response at this time.
As first reported by Camilo Andrés García today, a Twitter user named Alexánder tweeted a screenshot of a VMware ESXi server with a ransom note displaying 'Dear Keralty,' indicating that the healthcare company suffered a ransomware attack.
After seeing this tweet, BleepingComputer has since independently confirmed from a source that RansomHouse was behind the attack on Keralty.
RansomHouse has previously stated they conducted data-theft attacks on AMD and ADATA. However, ADATA denied they were attacked by RansomHouse and said the leaked data was from a previous RagnarLocker ransomware attack in 2021.
