Mill Bay Marine Group Listed by Securotrop Ransomware Group

On October 4, 2025, the Mill Bay Marine Group appeared on the leak site of the ransomware group Securotrop with 536 GB of internal files listed as exfiltrated.

What Public Reporting Shows

Public reporting indicates the Canadian marine services company was hit by a ransomware attack in which attackers copied internal documents before encrypting systems. The Securotrop group posted the victim’s name and a sample of the stolen data on its dark-web leak site, a common tactic used to pressure companies that have not paid. The total volume listed is 536 GB, though the exact number of people whose information is contained in those files remains unknown. The incident status on tracking sites remains listed as “awaiting,” meaning the group has published initial proof but has not yet released the full archive or set a firm public deadline.

Available reporting describes typical ransomware behavior in which customer records, employee payroll files, contracts, and operational spreadsheets are among the data most often taken. No confirmed list of exposed record types has been published by the company or the attackers at the time of writing.

Why This Matters for You and Your Family

When a local business like a marine group suffers a breach, the information stolen often includes names, addresses, phone numbers, email accounts, and financial details of ordinary customers and employees. If your family has ever bought a boat, booked a tour, worked with the company, or been listed as an emergency contact, your data could be sitting in that 536 GB archive. Once attackers release it, the information rarely stays contained. It spreads through forums, is sold in batches, and ends up fueling further fraud and harassment.
