The Hellcat ransomware group this week claimed responsibility for cyberattacks on Swiss telecommunications provider Ascom and British multinational car manufacturer Jaguar Land Rover (JLR).
The attack on Ascom occurred on March 16, and the group added the company to its Tor-based leak site on the same day. The telecoms company confirmed the next day that the attack targeted its technical ticketing system.
“The Ascom IT Cybersecurity Team is investigating the incident and immediately closed the ticketing system. Determining the extent of the attack is part of the ongoing investigation,” the company said.
