Miami Management Data Breach Lawsuit

The attack compromised sensitive data, potentially exposing the personal and financial information of both employees and clients.

Miami Management’s Data Breach Investigation

Miami Management, Inc., known for overseeing property management services in South Florida, reported that it became the target of a cyberattack by the Sarcoma ransomware group in late September 2025. According to a report from DailyDarkWeb.net, the ransomware group claimed responsibility for the attack and stated that they stole 2.4 terabytes (TB) of data from Miami Management’s network.

The stolen data allegedly contains highly sensitive personal and financial information. The breach potentially exposed:

• Driver’s license numbers
• Social Security numbers
• Financial information
• Names
• Dates of birth
• Addresses
• Other confidential files related to employees and clients

Given the nature of the data, the breach raises significant concerns regarding the potential for identity theft, financial fraud, and other malicious activities. At this time, it is unclear how many individuals were impacted or the full scope of the exposure, but the stolen data is considered a high-value target for cybercriminals.

Miami Management has yet to provide comprehensive public details regarding the full extent of the breach, but reports suggest that the company is actively working with cybersecurity experts to investigate and contain the incident.

When Did This Breach Occur?

The cyberattack took place in late September 2025, when the Sarcoma ransomware group successfully infiltrated Miami Management’s systems. The stolen data was reportedly 2.4 terabytes in size, indicating the scale of the breach. However, specific details about when the unauthorized access began or how long it lasted remain undisclosed. The breach was revealed shortly after the attack, but investigations are ongoing.

What Information Was Breached?

The data compromised in the Miami Management breach is extensive and includes a variety of sensitive personal and financial information. The exposed data may include:

• Driver’s license numbers
• Social Security numbers
• Financial information
• Names
• Dates of birth
• Addresses

In addition to these details, there may also be other confidential files related to employees and clients, heightening the potential risk for exploitation of the exposed data.
