HOST Software Entwicklung und Consulting GmbH Listed by qilin Ransomware Group

On February 24, 2025, the German software company HOST Software Entwicklung und Consulting GmbH appeared on the leak site of the qilin ransomware group. The listing indicates that internal files were exfiltrated during a ransomware attack on the developer of Ulysses ERP and MES software, which serves manufacturing SMEs in sectors such as plant construction, steel, and sheet metal work. Customers and partners whose information may have been stored in the company’s systems are now at risk of identity exposure.

Reported Details from Reporting

Public reporting indicates the incident involves data exfiltration rather than simple encryption. The qilin leak site lists HOST Software as a victim and provides samples of the stolen material. No exact victim count has been published, and the precise volume of data remains unclear. The company develops business software that handles sensitive operational records for small and mid-size manufacturers, so the exposed files could contain customer contracts, employee details, financial information, or technical configurations.

Available reporting describes the attack as following the group’s typical pattern: initial access, data theft, and subsequent extortion pressure. As of the publication date on the leak site, the company had not made any public statement confirming or denying the breach.

Why This Matters for You and Your Family

Even if you never bought Ulysses software directly, your personal or financial data may have been stored by a manufacturer that did. Suppliers, vendors, and service providers often keep copies of contracts, invoices, tax IDs, addresses, and contact details. When those records are stolen, the information can be sold or published, giving criminals an easy way to target you with phishing, identity theft, or harassment.

Children’s information is frequently included in family-linked business files. A single leaked address or parent email can expose a child’s name, school, or gaming username. Once that connection is made, attackers can move from corporate data to personal accounts in hours.

The Doxxing and Identity-Chain Risk

Ransomware leaks like this one rarely stop at the initial data set. Criminals map relationships between corporate emails, personal addresses, phone numbers, and online handles. A manufacturer’s leaked invoice might list your home address next to an order number; that address can be tied to your child’s Roblox or Minecraft account within minutes. The result is a doxxing chain that turns one breach into repeated harassment across work, home, and gaming environments.

Qilin’s Publicly Known Track Record

Public reporting attributes the qilin ransomware group with emerging in 2022. The group has targeted organizations across Europe and North America, including healthcare providers, manufacturers, and technology firms. Notable prior victims include companies whose internal documents were later published after failed ransom negotiations.

The typical qilin playbook begins with phishing or exploitation of remote desktop services for initial access. Operators then exfiltrate sensitive files before deploying ransomware. Extortion follows a double-pressure model: demands for payment to prevent file publication combined with threats to contact the victim’s customers directly. Leak sites are used to display proof and apply public pressure when companies resist.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, addresses, and online handles that may have been exposed in the HOST Software breach.
• Rotate any password you used at HOST Software or its customer portals anywhere else it is reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is caught and addressed in hours, not months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become the next link in doxxing chains after credential leaks like this one.
• Let remediation specialists handle takedown requests for any exposed personal records found on data broker sites or forums.

The incident shows that data held by vendors you never directly chose can still put your family at risk.
