On July 31, 2024, Kleven Construction, a U.S. company, was listed on the leak site operated by the hunters ransomware group. The listing states that internal files were exfiltrated during a ransomware attack in which both data encryption and data theft occurred. The exact number of people whose information appears in the stolen files remains unknown, as neither the leak-site posting nor any accompanying company notification has disclosed that detail.

Details from the Leak-Site Listing
The hunters ransomware leak site explicitly lists Kleven Construction as a victim, confirming that data was allegedly exfiltrated and that the victim’s systems were also encrypted. The entry does not specify the volume or precise categories of data taken, nor does it publish samples. Public views of the onion-site entry, preserved through ransomware.live, show the initial publication date as July 31, 2024. No formal breach notification from Kleven Construction has surfaced publicly at the time of this writing, so the full scope of exposed records stays unquantified.
Why This Matters for You and Your Family
When a construction firm’s internal files are stolen, the information often includes employee names, addresses, Social Security numbers, payroll records, tax forms, and vendor contracts. If your employer, your spouse’s employer, or a company you have done business with uses Kleven Construction, your personal details could be sitting in those files. Even without an exact count, the disclosure indicates that real people’s sensitive employment and financial data changed hands. That exposure does not disappear when the news cycle moves on; it remains available to identity thieves, fraudsters, and extortionists for years.
The Doxxing and Identity-Chain Risk
Stolen internal files frequently contain more than isolated records. They can link employee emails, personal phone numbers, dates of birth, and project details that attackers combine with other breaches to build complete identity profiles. A single leaked work email can lead to your LinkedIn account, your children’s school forms, or shared family cloud storage. These chains accelerate doxxing: once one handle is connected to your real name and address, subsequent leaks become far more damaging. Credential leaks like this one cascade into account takeovers, especially for gaming accounts belonging to you or your children that reuse the same passwords or security questions derived from employment paperwork.
