Decoline Listed by sarcoma Ransomware Group

On May 4, 2025, Belgian curtain and window-decoration company Decoline appeared on the leak site of the sarcoma ransomware group. Internal files were allegedly exfiltrated during a ransomware attack, exposing data that could affect customers, suppliers, and employees whose personal or financial details were stored in the compromised systems.

What's Publicly Reported from Reporting

Public reporting indicates that sarcoma listed Decoline on its data-leak portal after the company apparently declined to meet the group’s demands. The files taken include internal documents; exact volume and full contents remain undisclosed. Decoline, founded in 1990 and acquired in late 2019 by investment group Renardmont, supplies curtain-hanging systems and professional window-decoration solutions across Europe. No confirmed victim count has been published, and the precise date of initial compromise is not yet public. The incident follows the group’s standard pattern of encrypting systems, exfiltrating data, then publishing samples when ransom is not paid.

Why This Matters for You and Your Family

When a supplier like Decoline suffers a breach, your personal information used in orders, deliveries, or payments can end up in attackers’ hands. Addresses, phone numbers, email accounts, and payment records are typical in business files. Once leaked, this data fuels identity theft, phishing campaigns, and unwanted solicitations that reach you and your family at home. Children’s details sometimes appear in family-order records or school-related shipments, creating long-term exposure. Even if you never bought directly from Decoline, shared suppliers or partner networks can still place your information in the same compromised environment.

The Doxxing and Identity-Chain Implications

Stolen internal files often contain spreadsheets that link names, addresses, phone numbers, and email accounts. Attackers and subsequent buyers can chain these fragments with data from earlier breaches to build complete profiles. A single leaked order record can connect your work email to your home address and children’s names. That chain then spreads to gaming platforms, social media, and data-broker sites. Credential leaks of this type frequently cascade into account takeovers because people reuse passwords across work, shopping, and gaming services. Public reporting shows these chains accelerate doxxing, harassment, and financial fraud once the initial dataset appears on underground forums.

Sarcoma Group’s Known Track Record

Public reporting attributes the sarcoma ransomware group with operations that emerged in late 2023. The group has targeted mid-sized manufacturing, logistics, and retail firms across Europe and North America. Notable prior victims include other industrial suppliers and distributors whose internal documents were published after ransom negotiations failed. Their typical playbook involves initial access through phishing or exploited remote-desktop services, followed by lateral movement, data exfiltration, encryption, and dual extortion: demanding payment to decrypt systems and to prevent file publication. Deadlines are usually short, measured in days or weeks, after which samples are posted on their leak site.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, addresses, and online handles that may have surfaced in this or connected breaches.
• Rotate any password you used at Decoline or related supplier portals and enable 2FA through an authenticator app everywhere that password was reused.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure is caught in hours rather than months.
• Cover the household with DoxxScan family protection that includes dependents and children’s gaming accounts, which often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and leak sites on your behalf while you focus on securing daily accounts.

The Decoline incident illustrates how quickly supplier data leaks can reach ordinary families. Acting promptly limits how far attackers can build on the exposed information. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that explicitly protects children’s gaming accounts where credential leaks commonly lead to takeovers and doxxing. Starting protective steps now reduces the window attackers have to exploit this latest release.
