Mozo Grau (mozo-grau.com) Listed by Fog Ransomware Group

On February 13, 2025, the ransomware group known as fog added Mozo Grau to its leak site, claiming that it had exfiltrated internal files from the Spanish architecture and urban planning firm during a ransomware attack.

What Public Reporting Shows

Public reporting indicates the firm’s website, mozo-grau.com, was listed on the fog ransomware leak portal. The entry states that internal documents were taken. No exact victim count has been published, and the precise volume or types of files remain unclear from available screenshots and summaries. The listing appeared on the dark-web leak site hosted at an onion address tracked by ransomware.live. As of the publication date, fog had not posted sample data or set a public extortion deadline in the visible listing.

Why This Matters for You and Your Family

When architecture or planning firms are hit, the stolen files often contain contracts, client names, addresses, phone numbers, email accounts, and payment records. If your home, renovation, or planning application was handled by Mozo Grau, some of your personal information may now sit in an attacker’s archive. Internal files from such businesses routinely include scans of identity documents, tax details, and correspondence that can be pieced together with other leaks. For ordinary families this means another vector for identity theft, loan fraud, or unwanted contact long after the initial breach fades from the news.

The Doxxing and Identity-Chain Risk

Ransomware leaks rarely stay isolated. A single exposed email or phone number from a firm like Mozo Grau can be correlated with credentials from earlier breaches, creating a chain that reveals your full online footprint. Attackers link gaming usernames, family photos, children’s school accounts, and home addresses into a single profile. This is exactly how doxxing escalates: one document from an architecture firm becomes the missing link that lets someone harass your family or hijack accounts. Credential leaks like this one cascade into account takeovers when the same password or recovery details appear across personal and professional services.

Fog Ransomware Group Track Record

Public reporting attributes the fog ransomware operation to a group that emerged in 2024. It has targeted organizations across multiple countries, focusing on small and mid-sized businesses in professional services, manufacturing, and healthcare. Typical playbook involves initial access through phishing or exploited remote desktop services, followed by claimed exfiltration of sensitive files before encryption. The group then demands payment to prevent publication on its leak site. Past victims have faced both data exposure and operational encryption, with extortion pressure applied through direct contact and public listings.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity, then use the cleanup of Warden to remove what you can.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught in hours rather than months.
• Rotate any password you used at Mozo Grau or any related professional service, then replace it with a unique passphrase and enable 2FA through an authenticator app everywhere that account is reused.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often chain back to the same address or parent email and become targets after breaches like this.
• Let remediation specialists handle takedown requests across data brokers and exposed profiles that surface after the fog listing.

The incident is a reminder that professional-service breaches now feed directly into personal doxxing chains. Starting with a clear picture of where your information already appears online remains the most practical defense. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.
