A Miami Management data breach lawsuit has not yet been filed, but multiple law firms opened investigations in early 2026 after the South Florida property management company disclosed that a September 2025 ransomware attack exposed the personal information of 3,338 people. Shamis & Gentile P.A. was actively soliciting potential claimants as of March 2026, and attorneys working with ClassAction.org also looked into the incident.1ClaimDepot.

What Happened in the Breach
The Sarcoma ransomware group claimed responsibility for the attack on September 22, 2025, and said it had exfiltrated 4.9 terabytes of data from Miami Management’s network. Roughly 2.4 terabytes of that data was posted as samples on the dark web, and the group threatened to release the rest if the company refused to negotiate.3DeXpose.

Status of the Class Action Investigations
No formal class action complaint had been filed as of early 2026. Shamis & Gentile P.A. was investigating the matter and accepting inquiries from people who received notice letters.1ClaimDepot.

What a Lawsuit Would Have to Show
The legal theories being explored center on whether Miami Management failed to implement adequate data security measures to protect the personal information it held. In comparable data breach cases, plaintiffs typically seek compensation for identity theft risks, financial losses, and emotional distress.
If you received a notice letter, keep it. Save any records showing fraudulent charges, new accounts opened in your name, or time spent responding to the breach; those documents tend to matter if a class action is filed and a claims process opens. Enrolling in the free monitoring Miami Management offered through Epiq is a separate step and does not close off future legal options.
