Recent reports have suggested that global security and building automation solutions provider, Johnson Controls, has been hit by a major cyber-attack.
The ransomware attack is said to have had a significant impact, leaving data encrypted and forcing shutdowns across the company’s IT infrastructure.
According to Bitdefender, The Dark Angels ransomware group has claimed responsibility.
The group reportedly exfiltrated over 25 TB of data from Johnson Controls and is now demanding a ransom of $51m.
If the ransom is not paid, the group has said it will publish the stolen data on the Dunghill Leaks site.
“We are currently experiencing IT outages that may limit some customer applications such as the Simplex Customer Portal,” said a website message from Simplex, a subsidiary of Johnson Controls.
“We are actively mitigating any potential impacts to our services and will remain in communication with customers as these outages are resolved.”
