Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Reported Details of the Incident

Public reporting indicates that LockBit5 claims to have stolen internal company documents during a ransomware attack on RITTA. The victim is a well-known Thai firm that provides architectural design, engineering, and construction services across residential, commercial, and infrastructure projects. No specific count of affected individuals has been released, and the precise volume or content of the stolen files remains unclear from available reporting. The listing appeared on the LockBit5 leak site, which is accessible via the Tor network.

Internal files were allegedly exfiltrated, a common tactic used by the group to pressure victims into payment. RITTA has not yet issued a public statement confirming the breach or detailing what customer, employee, or partner information may have been inside the stolen documents.

Why This Matters for You and Your Family

When a company like RITTA suffers a breach, the ripple effects reach ordinary people. Clients, suppliers, employees, and their families often have personal details stored in project contracts, invoices, employment records, or vendor databases. If those records were taken, your names, addresses, phone numbers, email accounts, or payment details could now sit on a criminal leak site.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
