Dinnebiergruppe.de Listed by Cloak Ransomware Group

On February 19, 2026, German car dealer group Dinnebiergruppe.de appeared on the leak site of the cloak ransomware operation after its internal files were allegedly exfiltrated during a ransomware attack.

Reported Details of the breach

Public reporting indicates that cloak actors gained access to Dinnebiergruppe’s networks, encrypted systems, and then published proof of the stolen data on their leak portal. The company, an authorised dealer for Mercedes-Benz, smart, Audi, Porsche, and Volkswagen Commercial Vehicles, also operates in real estate, hotels, and petrol stations. No confirmed victim count has been released, and the precise volume or sensitivity of the exfiltrated files remains unclear from available reporting. The listing on the cloak leak site serves as the primary public confirmation of the incident.

Why this matters for you and your family

When a company that handles vehicle sales, leasing, financing, insurance, and property records is breached, the information it stores often includes names, addresses, dates of birth, phone numbers, email addresses, banking details, and vehicle identification numbers tied to ordinary customers. If you or anyone in your household has ever bought, leased, serviced, or insured a car through Dinnebiergruppe or its affiliated businesses, your personal data may now sit in an attacker’s archive. That data does not expire, and it can be combined with other leaks to build a detailed profile that puts your family at risk of identity theft, fraudulent loan applications, or targeted scams.

The doxxing and identity-chain risk

A single breach rarely stays isolated. Attackers routinely cross-reference leaked customer records against usernames, gaming tags, social-media handles, and phone numbers found in earlier dumps. This creates an identity chain that can expose your home address, children’s names and ages, and even their online gaming accounts. Once the chain is built, doxxing, swatting, or account takeovers become far easier. Credential leaks like this one frequently cascade into gaming platforms because families often reuse the same email-password combinations across work, car dealership portals, and children’s Roblox, Fortnite, or Steam accounts.

cloak group’s known track record

Public reporting attributes the cloak ransomware group with emerging in late 2024 and focusing on mid-sized European companies. Notable prior victims include other automotive and retail organisations across Germany and neighbouring countries. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by claimed exfiltration of internal files, deployment of ransomware, and then dual extortion: demanding payment to decrypt systems while threatening to publish the stolen data on their leak site if the ransom is not paid by their deadline.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what this claimed breach connects to.
• Rotate any password you ever used on Dinnebiergruppe.de or its partner portals anywhere else it is reused, and switch on 2FA using an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts that often chain back to the same leaked addresses and emails.
• Let remediation specialists handle takedown requests across data brokers and exposed records while you focus on securing your own accounts.
