On August 21, 2025, the Akira ransomware group listed Blazer Building on its leak site and announced it would publish roughly 10 GB of the construction company’s internal files. The data includes employee records containing dates of birth, home addresses, Social Security numbers, phone numbers, and even pet names, along with HR documents, customer files, financial records, contracts, violation reports, and police reports.

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.

What Public Reporting Shows
Public reporting indicates that Blazer Building, a general contractor focused on fast-track apartment construction, was compromised in a ransomware incident. The attackers claim to have exfiltrated the files before encrypting systems or disrupting operations. The leak site posting explicitly lists the categories of sensitive information now at risk of public release. No exact number of affected individuals has been confirmed, but the volume and detail described suggest the exposure touches current and former employees, their families, and customers whose records were stored in the company’s systems.
August 21, 2025 marks the date the group made the data public on its leak portal. The sample descriptions provided by the attackers match the types of records that, once leaked, are quickly scraped and resold on underground forums.
Why This Matters for You and Your Family
When a company that holds your personal information suffers a breach like this, the fallout lands directly on you. A single exposed Social Security number combined with an address and date of birth can be used to open accounts in your name, file fraudulent tax returns, or impersonate you with banks and government agencies. If you or a family member ever worked with or lived in a property managed by Blazer Building, your information may now be circulating. Children’s records are sometimes included in HR or tenant files, creating long-term risks that parents must address immediately.
