On October 16, 2025, Polish IT services provider M3 Group Sp. z oo appeared on the leak site of the nova Ransomware Group. The company, which supplies IT support, custom software development, web applications, system implementation, consulting, and infrastructure solutions to businesses across Poland, is claimed to have had internal files exfiltrated during a ransomware incident. While the exact number of individuals whose data may have been exposed remains unknown, anyone whose personal or financial records passed through M3 Group’s systems could now be at risk.

What Public Reporting Shows
Public reporting indicates that nova Ransomware Group listed M3 Group after the company apparently declined to pay a ransom demand. The attackers claim to have stolen internal files and posted a sample on their dark-web leak site. Available details describe the exposed material as sensitive internal documents rather than a simple database dump. No confirmed total of affected records has been released, and the precise date of initial compromise is not yet public. The incident follows the group’s standard pattern of exfiltration before encryption, with the leak serving as leverage for extortion.
Why This Matters for You and Your Family
If you or any member of your family has done business with an organization that relied on M3 Group for IT support or software services, your personal information may have been inside the stolen files. Internal files often contain contracts, invoices, employee records, customer databases, or scanned documents that include names, addresses, tax identification numbers, email accounts, and payment details. Once such data leaves a company’s control, it can be sold, traded, or used to launch further attacks against you. For ordinary families this means a higher chance of identity theft, fraudulent loan applications, or targeted phishing emails that look legitimate because they reference real past transactions.
The Doxxing and Identity-Chain Implications
Stolen internal files frequently contain more than isolated records. They can link your work email to personal phone numbers, home addresses, spouse names, and even details about children. These connections allow criminals to build an identity chain that jumps from one account to another. A single leaked credential from this claimed breach can be tested across banking, government, and retail sites. When those attempts succeed, attackers can lock you out, demand ransom, or publish your information on doxxing forums. Gaming accounts belonging to you or your children are especially vulnerable because kids often reuse simple passwords or email addresses that appear in family-linked business records.
