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.

Confirmed Facts from Reporting

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.

The Doxxing and Identity-Chain Risks

Stolen company files frequently contain spreadsheets that link personal emails to real names, addresses, and sometimes dates of birth. Attackers combine this information with data from earlier breaches to build detailed profiles. One exposed work email can lead to discovery of personal social-media handles, gaming usernames, and even family photos. These chains make doxxing faster and more damaging. Credential leaks like this one regularly cascade into account takeovers on gaming platforms, where children’s accounts become entry points for further harassment or extortion.

MedusaLocker’s Public Track Record

Public reporting attributes MedusaLocker with emerging in late 2019. The group has targeted organizations across multiple countries, encrypting systems and then publishing stolen data when victims refuse to pay. Their typical playbook involves gaining initial access through vulnerable remote desktop services or phishing, exfiltrating files before encryption, and then demanding ransom with a deadline. If unpaid, they publish samples on their leak site and threaten full data release. Past victims have included healthcare providers, manufacturers, and logistics firms, according to ransomware trackers.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real identity so you can see exactly what this breach may have exposed.
• Rotate any password you used at SIT Group, Robusta, or abv.bg and enable 2FA with an authenticator app on every account where that password was reused.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next leak that touches your family is caught in hours rather than months.
• Cover the household with DoxxScan family protection, which includes dependents and children’s gaming accounts that often chain back to the same addresses and emails.
• Let remediation specialists handle takedown requests across data brokers and suspicious sites while you focus on securing your own accounts.

The reality is that ransomware groups like MedusaLocker will keep targeting companies that hold ordinary people’s information. Taking concrete steps now limits how far any single breach can reach. DoxxScan by GalaxyWarden provides continuous monitoring across 15.4 billion breach records and more than 100 platforms, AI-powered identity-chain mapping that connects scattered online handles to real identities, and hands-on remediation by specialists who manage takedowns for you. Its household coverage extends to children’s gaming accounts that are frequently swept up in these cascading leaks.
