SIT Group / Robusta Listed by Medusalocker Ransomware Group

On May 5, 2026, the MedusaLocker ransomware group added Italian company SIT Group and Bulgarian firm Robusta to its public leak site, exposing internal files stolen during a ransomware attack. Customers, employees, and anyone whose personal information appears in those files now face the risk that their data could be sold or published in full.

What Public Reporting Shows

Public reporting indicates that the incident involves SIT Group (sitgroup.it) and Robusta (robusta.bg), along with email addresses from the abv.bg domain. The attackers exfiltrated internal files before encrypting systems and later listed both companies on their dark-web leak page. No exact victim count has been released, and the precise volume or sensitivity of the stolen data remains unclear from available reporting. The listing appeared on the MedusaLocker leak site, which is tracked by ransomware monitoring services such as ransomware.live.

Why This Matters for You and Your Family

When companies like these suffer breaches, the information inside employee records, customer databases, or vendor files often includes names, addresses, phone numbers, email accounts, and sometimes financial details. If any of that data belongs to you or someone in your household, it can be used to impersonate you, open accounts in your name, or target your family with phishing and identity theft. Children’s records are especially vulnerable because parents frequently link family emails or phone numbers across work, school, and gaming accounts.

A single leak can quietly sit for months before criminals exploit it. By the time you notice unusual charges or strange mail, the damage may already be done.
