The Marena Group Listed by Kairos Ransomware Group

On February 13, 2026, the kairos Ransomware Group listed The Marena Group on its leak site, claiming that internal files including a set of SQL databases had been exfiltrated from the medical compression garment manufacturer.

What Public Reporting Shows

Public reporting indicates that Marena, a company that has spent 30 years developing and manufacturing medical-grade compression garments for patient recovery and long-term wellness, was hit by a ransomware operation. The attackers extracted internal documents and databases before encrypting systems or otherwise disrupting operations. Available reporting describes the exposed material as containing SQL databases, though the exact number of records and the specific categories of personal information inside those databases have not been publicly detailed. No confirmed victim count has been released, leaving patients, employees, and business partners uncertain about whether their information is among the stolen data.

The listing appeared on the kairos leak site, a common tactic used by ransomware groups to pressure victims into payment by threatening to publish or sell the data. As of the publication date, it remains unclear whether any samples or full datasets have been released to the public.

Why This Matters for You and Your Family

When a healthcare-adjacent company like Marena suffers a breach, the ripple effects reach ordinary families. Medical compression products are frequently prescribed after surgery, during pregnancy, or for chronic conditions. If your name, address, phone number, email, or insurance details ever passed through Marena’s systems, that information may now sit in an attacker’s hands. SQL databases commonly store customer orders, patient support records, and supplier contacts, any of which can be pieced together with data from other breaches.
