Major airline technology provider Accelya which counts American Airlines, Delta, and British Airways as some of its clients had some of its servers compromised by the ALPHV ransomware gang, also known as BlackCat, reports The Record, a news site by cybersecurity firm Recorded Future. Some of the data allegedly stolen from Accelya, including emails and worker contracts, have already been leaked by ALPHV ransomware last week, with the transport technology service provider still verifying the exposed data. However, Accelya has already enlisted third-party experts to prevent the ransomware from compromising other systems. "Our forensic investigators confirmed it was limited to a contained portion of our overall environment. We have no evidence to indicate that the malware could have moved laterally from our systems to our customers environments," said an Accelya spokesperson. Prior to the Accelya attack, ALPHV ransomware has most recently compromised two Luxembourg energy firms, as well as Bandai Namco.
