Data exposed Internal files exfiltrated in ransomware attack

On June 25, 2026, construction company Fonsan appeared on the leak site of the Booba Project ransomware group after 23.4 GB of its internal files were exfiltrated in a ransomware attack.

Confirmed Facts from Public Reporting

Public reporting indicates the incident involved a ransomware deployment that led to both encryption and data theft. The attackers published a sample of the stolen material on their leak portal, hosted via ransomware.live. Available details list the exposed volume at 23.4 GB of internal files, though the exact number of people whose personal information was contained remains unknown. No confirmed timeline for initial access or the precise date of encryption has been released by the company or the threat actors.

The data category is described simply as internal files. In construction firms like Fonsan this commonly includes employee records, vendor contracts, project bids, and customer information. Public reporting attributes the claim to the group’s own leak page.

Why This Matters for You and Your Family

When a company that handles contracts, payments, or background checks for homes, renovations, or commercial builds is breached, the information stolen can include your address, phone number, email, Social Security number, or banking details. 23.4 GB is large enough to hold thousands of such records. Once that material circulates on criminal forums, it can be used for identity theft, loan fraud, or targeted phishing against you and your family.

Even if your name is not on the initial sample posted, ransomware groups routinely release additional batches or sell the full archive. The uncertainty about who is affected means anyone who has done business with Fonsan should treat their own data as potentially exposed.

The Doxxing and Identity-Chain Implications

Stolen internal files often contain spreadsheets that link names, addresses, emails, and phone numbers. Criminals combine this information with data from earlier breaches to build detailed profiles. A single leaked work email can lead to discovery of personal accounts, family member names, and even children’s gaming usernames. These identity chains allow attackers to move from one platform to another, turning a corporate breach into personal doxxing or account takeovers.

Credential leaks like this one cascade into gaming account compromises when the same password or security question is reused. Children’s profiles on popular gaming platforms are frequent secondary targets because parents often share email addresses across work, family, and kid-related logins.

Booba Project’s Publicly Known Track Record

Public reporting attributes the Booba Project ransomware group with activity that emerged in late 2024. The group has claimed responsibility for attacks on organizations across multiple sectors, typically following a double-extortion playbook: deploy ransomware to encrypt systems, exfiltrate data before encryption, then demand payment to prevent publication. Notable prior victims listed on open trackers include mid-sized companies in manufacturing, logistics, and professional services. Their leak site follows the now-standard model of posting proof files, countdown timers, and eventual full data dumps if ransom is not paid.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with no-subscription cleanup handled by the service.
  • Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next exposure of your information is caught in hours rather than months.
  • Rotate any password you used at Fonsan anywhere else it appears, and switch on 2FA using an authenticator app instead of text messages.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that chain back to the same address or parent email.
  • Let remediation specialists perform hands-on takedown requests across data brokers and leak sites on your behalf.
