umi-tiles.com Listed by lockbit3 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure organisations by listing alleged victims on dedicated leak sites, turning data theft into a public spectacle intended to force payment. In this climate of double-extortion tactics, even mid-sized manufacturers can find themselves named without immediate independent confirmation of the full scope. On 21 January 2024, umi-tiles.com appeared on such a listing attributed to the LockBit3 group, highlighting how industrial firms remain attractive targets for operators seeking leverage through stolen internal material.

Public detail remains limited: the listing asserts that internal files were exfiltrated in a ransomware attack, yet the number of people affected is unknown and no further technical specifics have been released. The incident matters because any confirmed compromise of corporate systems can expose operational data, employee records or partner information, creating lasting risks for those whose details may have been involved.

Inside the incident

According to the available record, umi-tiles.com was listed by the LockBit3 ransomware group on 21 January 2024. The group claims that internal files were exfiltrated during a ransomware attack. No independent verification of the claim, the precise timing of any intrusion, the volume of data taken, or the method of access has been made public. The number of individuals potentially affected is listed as unknown. Beyond the assertion of file exfiltration, the record does not describe encryption of systems, ransom demands, or any subsequent publication of the material itself. All further operational details remain undisclosed.

The group behind it: lockbit3

LockBit3 is a well-documented ransomware-as-a-service operation that has been active for several years. The group typically gains initial access through phishing, exploited vulnerabilities or compromised credentials, then deploys ransomware that encrypts systems while simultaneously stealing data. Its operators maintain a leak site where they name victims and threaten to publish stolen material if payment is not made—a classic double-extortion model. LockBit affiliates have previously targeted organisations across manufacturing, logistics, healthcare and government sectors worldwide, often releasing sample files to demonstrate possession of data. In this case the group claims umi-tiles.com as a victim; that listing should be treated as an unverified assertion unless corroborated by the organisation or independent investigators. No specific statements by LockBit3 about the contents of any umi-tiles.com files beyond the general claim of internal-file exfiltration appear in the public record.

About umi-tiles.com

umi-tiles.com is associated with Saha Mosaic Industry Public Company Limited, a Thai manufacturer founded on 6 June 2016 and listed on the Stock Exchange of Thailand the same year. The company produces ceramic and porcelain tiles sold under the Duragres brand, a name intended to convey strength and durability, and has positioned itself as a leader in digital printing technology for tile design. Firms of this type routinely manage production schedules, supplier contracts, quality-control records, employee information, customer orders and financial data. A breach involving such an organisation is consequential because manufacturing operations depend on continuous supply-chain coordination and because any exposure of internal files can affect employees, business partners and, indirectly, end customers who rely on the integrity of the products and the company behind them.

The information in question

The only data type named in the record is “internal files exfiltrated in a ransomware attack.” No further breakdown—such as whether the material included employee personal data, financial records, intellectual property, customer lists or production specifications—has been disclosed. Organisations in the tile-manufacturing sector typically hold human-resources files, payroll details, supplier agreements, design files, inventory systems and correspondence with distributors. Because the exact contents remain unconfirmed, it is not possible to state with certainty which categories of information, if any, were taken. Readers should therefore treat any specific claims about the nature of the files as unverified until official confirmation is provided.

The real-world impact

For individuals whose personal details may have been among the internal files, the practical risks include potential identity misuse, targeted phishing or social-engineering attempts that reference genuine company information. Employees could face inconvenience if payroll or contact data were exposed; partners and suppliers might see contractual or pricing details used against them in negotiations. For the organisation itself, the listing can damage commercial reputation, disrupt operations if systems were encrypted, and trigger regulatory scrutiny under data-protection rules applicable in Thailand and any jurisdictions where customers or partners are located. Because the scale of the alleged exfiltration is unknown, the full extent of these effects cannot yet be measured. The absence of confirmed victim counts means many people may remain uncertain whether they are personally affected.

What to do if you're exposed

If you have a past or present connection to umi-tiles.com or Saha Mosaic Industry—whether as an employee, contractor, supplier or customer—monitor financial accounts and credit reports for unusual activity and treat unexpected emails or calls that reference the company with caution. Change passwords on any accounts that may have shared credentials with work systems, enable multi-factor authentication where available, and consider placing fraud alerts with relevant credit bureaus. Keep records of any suspicious contact. Readers can also run a free exposure scan of their email address to check whether their information has already surfaced in known breach data sets; such a check provides an early indication of wider circulation even when the original incident details remain limited.
