tks.co.th Listed by lockbit3 Ransomware Group

On November 4, 2023, Thai company T.K.S. Technologies PCL appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack. The company, founded in 1954, produces business forms, security printing, and office supplies. Anyone whose personal or employment records sit inside those files now faces long-term exposure.

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.

Primary Disclosure Details

The LockBit 3.0 leak page explicitly lists tks.co.th and claims successful data theft from the victim’s systems. It does not publish the volume of records taken, nor does it specify exact file types beyond the general description of internal files exfiltrated. The notification provides no count of affected individuals and sets no public deadline in the visible listing. Public reporting on LockBit 3.0 indicates the group typically posts proof-of-exfiltration samples and later releases full archives if ransom demands remain unmet. The exact ransom amount and any negotiation details remain unknown because the primary disclosure does not state them.

Why This Matters for You and Your Family

When a company that prints security forms and business documents is breached, the stolen material often contains names, addresses, tax identifiers, employee payroll data, and customer order records. Even without an exact victim count, the exposure is real for anyone who has worked at T.K.S., ordered custom forms, or had sensitive documents processed by them. Internal files from a printing firm frequently include scanned copies of official paperwork that carry signatures, identification numbers, and contact details. Once those records leave the company’s control, they can surface on dark-web markets for years, feeding identity theft, loan fraud, and targeted scams against you or your family members.

Doxxing and Identity-Chain Risks

Stolen internal files rarely stay isolated. Threat actors combine employee spreadsheets, customer databases, and email archives to build detailed profiles. A single leaked work email can link to personal accounts, home addresses, and family relationships. This creates doxxing chains that expose children’s names, school details, or even gaming usernames tied to the same household. Credential leaks of this nature frequently cascade into account takeovers on gaming platforms, where stolen corporate logins are tested against Steam, Roblox, or Discord. The result is not only financial loss but also harassment and privacy invasion that reaches every member of the household.

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.
