Colombian healthcare provider Keralty, which has a network of hospitals and medical centers in the U.S., Latin America, Spain, and Asia, had its company and subsidiary websites and operations disrupted by a RansomHouse ransomware attack on Sunday, reports BleepingComputer.
Colombia's healthcare system has been significantly impacted by the attack on Keralty, which initially reported on Monday that it was experiencing technical issues before finally revealing the following day that its servers have been subjected to a cyberattack.
Investigation into the incident is ongoing and Keralty has already sought the assistance of law enforcement authorities.
Meanwhile, BleepingComputer has associated a "Dear Keralty" ransom note on a VMware ESXi server shared by a Twitter user and initially reported by Camilo Andrs Garca to the RansomHouse ransomware operation.
RansomHouse has since confirmed to have conducted the attack on Nov. 27, from which they have allegedly stolen 3TB of data from Keralty. Such an attack comes after the group claimed to launch attacks against AMD and ADATA.
CNN reports that a potential compromise of the Department of Homeland Security's sensitive physical security details is being looked into by the department's senior officials following a ransomware attack against contractor and major building automation systems manufacturer Johnson Controls International.
Most organizations impacted by ransomware attacks have been noted by the FBI to be experiencing another intrusion involving a different ransomware variant within 48 hours of each other, BleepingComputer reports.
