On September 2, 2025, the DiMarco Group appeared on the leak site of the lynx ransomware group, with the attackers claiming to have exfiltrated internal files from the 115-year-old Rochester, New York real estate and construction company.

What's Publicly Reported from Reporting

Public reporting indicates the DiMarco Group, founded in 1910 and based in Rochester, provides real estate development, construction management, property management, facilities maintenance, and equipment services. The lynx ransomware operators listed the company on their dark-web leak page, stating they had obtained internal documents during a ransomware incident. The exact number of affected individuals remains unknown, and the precise volume or sensitivity of the files has not been independently verified. Available reporting describes the posting as part of the group’s standard extortion process, in which stolen data is published if demands are not met.

Why This Matters for You and Your Family

When a company like DiMarco Group that handles property records, vendor contracts, employee information, and potentially tenant or client personal data suffers a breach, the consequences reach far beyond the business. Internal files often contain names, addresses, dates of birth, Social Security numbers, financial details, or correspondence that can be used to target you or your family members. If your landlord, employer, contractor, or service provider uses DiMarco Group, your information may have been caught in the exfiltration. Once exposed, these records can fuel identity theft, loan fraud, or targeted scams that affect everyday finances and peace of mind.

The Doxxing and Identity-Chain Implications

Ransomware leaks rarely stop at one company’s files. A single exposed email, phone number, or username can link to your accounts across dozens of other services. Attackers and opportunistic criminals follow these chains to map your digital footprint, locate family members, and escalate from data theft to full doxxing. Credential leaks like this one frequently cascade into account takeovers on email, banking, or social media, and children’s gaming accounts are especially vulnerable because they often reuse the same passwords or recovery emails tied to a family address. The result can be harassment, swatting, or long-term privacy erosion that continues for years after the initial breach.

Lynx Ransomware Group’s Track Record

Public reporting attributes the lynx ransomware group with emerging in late 2024 as a double-extortion operation. The group is known for targeting mid-sized businesses in construction, manufacturing, and professional services. Its typical playbook involves initial access through phishing or exploited remote desktop protocols, followed by exfiltration of sensitive files before deploying ransomware. If payment is not received, lynx publishes samples or full datasets on its leak site to pressure victims. Notable prior incidents have involved similar real-estate and facilities-management companies, though exact victim counts and outcomes are often obscured by ongoing negotiations.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the included cleanup of data broker records tied to the breach.
• Rotate any password you used at DiMarco Group or its affiliated services anywhere it has been reused, and immediately enable two-factor authentication through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next leak exposing you or your family is caught within hours instead of months.
• Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same addresses and recovery details.
• Let remediation specialists handle takedown requests and negotiations with data brokers and leak sites on your behalf while you focus on securing day-to-day accounts.
