On March 13, 2025, the Chinese website of construction-materials manufacturer Laticrete was listed on the leak site of the J Ransomware Group. Internal files were allegedly exfiltrated during a ransomware attack on laticrete.com.cn, exposing data that could affect customers, suppliers, and anyone whose personal or business information was stored in those systems.

What Public Reporting Shows
Public reporting indicates the J Ransomware Group added Laticrete’s China branch to its data-leak portal on that date. The company, known for tile and stone installation systems, masonry products, concrete chemicals, and restoration materials, maintains laticrete.com.cn as its dedicated site for the Chinese market. Available reporting describes the incident as a ransomware attack in which internal files were taken; the exact number of people affected remains unknown. No specific samples of the stolen data have been publicly detailed beyond the group’s claim of successful exfiltration.
Why This Matters for You and Your Family
When a company that supplies building materials to contractors and homeowners suffers a breach, the fallout can reach ordinary families. Internal files often contain names, addresses, phone numbers, email accounts, payment records, or project details tied to residential renovations, new builds, or retail purchases. If your information was included, it can be sold or published, increasing the risk of identity theft, phishing, or unwanted solicitations. For families, a single leak can expose shared household details that connect parents, children, and even gaming accounts registered with the same email or phone.
March 13, 2025 marks the public disclosure on the leak site, starting a clock during which the attackers may escalate pressure. The uncertainty around the volume of data taken makes it prudent to treat the incident as potentially relevant to anyone who has done business with Laticrete in China or whose information could have been shared with them.
