Jet engine dealer to major airlines discloses 'unauthorized activity'

Willis Lease Finance disclosed a cybersecurity incident after data allegedly stolen by the Black Basta ransomware group—claimed to be ~910 GB of corporate and sensitive personal documents including passports and SSNs—was posted to the group's leak site; the company took systems offline, engaged third-party investigators, implemented workarounds to continue operations, and reported the incident to law enforcement while containment efforts were reported complete.
