Finastra, a major financial software provider, has confirmed a data breach after a hacker claimed to have stolen 400GB of data from the company.
The hacker offered the stolen data for sale on a cybercrime forum, including sensitive client files and internal Finastra documents.
Finastra detected suspicious activity on November 7th within its internally hosted Secure File Transfer Platform (SFTP), but the exact number of affected customers and the nature of compromised data is still unknown.
The breach may have resulted from compromised user credentials, and Finastra's investigation into the incident is ongoing.
