BleepingComputer reports that The Philadelphia Inquirer was claimed to be compromised by the Cuba ransomware operation in a cyberattack this month, which resulted in the publication's most significant disruption in over 25 years. Cuba ransomware has announced on its data leak site that several files have been stolen from The Inquirer's computers on May 12. All of the exfiltrated documents including financial files, account movements, bank employee correspondences, tax documents, compensation, account movements, and source code have been leaked for free, suggesting The Inquirer's refusal to provide ransom demanded by Cuba ransomware. The Inquirer has yet to comment on the status of its systems following the ransomware attack or whether the attack has compromised customer information. Cuba ransomware was previously reported by the FBI to have amassed $60 million from attacks as of last August and has since been associated with phishing attacks with the ROMCOM RAT malware against Ukrainian government agencies.
