On August 23, 2024, engineering firm Tahly Engineering & Associates, Inc. appeared on the leak site operated by the dAn0n ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the company’s network. The firm, founded in 1970 and based in Helena, Montana with a branch in Bozeman, provides transportation and civil engineering services across the region. The exact number of people whose information was taken remains unknown, and the leak-site posting does not detail the specific documents or data types 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 dAn0n leak site lists Tahly Engineering under its active extortion page, claiming that data was stolen and that the company has not yet met the group’s demands. The posting, first indexed on August 23, 2024, includes a sample of allegedly stolen material but does not quantify records or name the precise systems compromised. Public mirrors of the onion site, such as ransomware.live, preserve the original listing without adding unverified claims. The disclosure indicates the incident follows the group’s standard pattern of initial access, data theft, and subsequent public shaming when payment is refused.
Why This Matters for You and Your Family
When a local engineering company like Tahly is breached, the information exposed often includes details that reach beyond employees. Clients, subcontractors, vendors, and residents whose project records or personal data sit in those internal files can find themselves at risk. Internal files exfiltrated in ransomware attacks frequently contain names, addresses, dates of birth, Social Security numbers, financial records, and correspondence that tie real people to specific projects or contracts. For families in Montana who have worked with the firm on home builds, road improvements, or land development, this means your information could now sit in an attacker’s archive. Even if you never directly hired them, shared municipal or utility projects can place your data in the same systems.
Doxxing and Identity-Chain Risks
Stolen internal files rarely stay isolated. Attackers and downstream criminals map email addresses, phone numbers, and project references to personal accounts across the web. A single engineering contract can link your home address to usernames used on government portals, vendor logins, or family email. These connections create doxxing chains that let criminals escalate from leaked documents to targeted phishing, account takeovers, and identity theft. Credential leaks of this kind also cascade into gaming platforms. Children’s usernames or parent-linked emails reused from work accounts become entry points for harassment or further data theft. The longer the material remains available on the dAn0n site or its mirrors, the higher the chance that multiple threat actors will obtain and exploit it.
