StarBucks Failed to reach out to us and didn't pay even $500,000 when we know they can afford it. It's not even that much we were asking for. Since you didn't contact is no negotiations and this is now in the hands of cybercriminals. This is a warning to all companies if you see yourself posted here to reach us. This is the only ammount we have on are servers due to migrating dmca and ignore abuse infrastructure. They were breached on 04/01/2026 and they know they were breached because they closed the s3 bucket starbucks-prod.
