K Subsea Group Listed by Everest Ransomware Group

On April 13, 2026, Singapore-based offshore energy services provider K Subsea Group appeared on the leak site of the Everest ransomware group. The company, which employs more than 800 staff across Southeast Asia, is claimed to have had internal files exfiltrated after a ransomware attack. Public reporting indicates that customer records, employee information, and operational documents may have been taken, although the precise number of people affected remains unknown.

Reported Details of the Breach

Available reporting describes the incident as a classic ransomware operation in which attackers first gained access, encrypted systems, and then exfiltrated data before demanding payment. The Everest group published proof of the breach on its dark-web leak site on April 13, 2026. K Subsea has not yet issued a public statement confirming the scope, but the presence of the company’s name on the leak site is treated as credible by multiple ransomware-tracking services.

Internal files were the primary material exfiltrated. Because K Subsea provides integrated subsea solutions to the energy sector, these files likely contain contracts, employee details, vendor information, and possibly personal data belonging to both staff and clients. No evidence has surfaced that payment was made or that the data was subsequently removed from the leak site.

Why This Matters for You and Your Family

Even when a breach hits a company rather than a consumer app, ordinary families feel the impact. If you or a family member works at K Subsea, had business with the firm, or appears in any vendor or partner records, your personal information may now sit in a ransomware data dump. Names, addresses, phone numbers, email accounts, and employment details are common contents of such leaks. Once posted, that information rarely disappears.
