A prominent South Florida property management company has become the latest victim in a string of sophisticated cyberattacks, resulting in the exfiltration of a staggering 4.9 terabytes of personally identifiable information (PII). Miami Management, a leader in its regional market, recently confirmed that it suffered a significant security incident involving a notorious ransomware group, exposing the sensitive data of an undisclosed number of individuals. The breach, which unfolded in late 2025, highlights the persistent and evolving threat that ransomware poses to organizations holding large volumes of personal data. The attack not only involved the encryption of systems but the theft and subsequent public exposure of sensitive files, a double-extortion tactic increasingly favored by cybercriminals. This event serves as a critical reminder of the vulnerabilities present within corporate networks and the far-reaching consequences for individuals whose information is compromised, thrusting them into a prolonged battle to safeguard their identities against potential fraud and misuse. The company is now navigating the complex aftermath of the incident, from regulatory disclosures to providing support for those affected.
1. Timeline of the Security Incident
The initial signs of trouble emerged on September 10, 2025, when Miami Management detected unusual activity within its digital infrastructure, prompting an immediate internal response. A subsequent investigation, conducted with the assistance of external cybersecurity specialists, determined that an unauthorized actor had gained access to company systems for a full month, from September 8 to October 9, 2025. During this period, the intruder had the opportunity to view or copy a vast repository of files. The situation escalated dramatically on September 22, 2025, when the Sarcoma ransomware group publicly claimed responsibility for the attack on a dark web forum. The group substantiated its claim by posting the company’s full domain name and sharing a 2.4 TB sample of the stolen data, while asserting that they had exfiltrated a total of 4.9 TB. The cybercriminals issued a stark ultimatum, threatening to publish the entire dataset within a week if their demands were not met. The breach notification filed with the New Hampshire Attorney General on February 2, 2026, confirmed that the exposed PII included names and driver’s license numbers, affecting at least one resident of that state, though the total number of victims remains unspecified.
2. Mitigation Measures and Consumer Guidance
In response to the breach, Miami Management initiated a series of measures aimed at securing its network and assisting affected individuals. The company immediately moved to contain the threat and launched a comprehensive investigation to understand the full scope of the compromise. This involved a meticulous review of all potentially affected files to identify what specific information was accessed and who was impacted. Following this analysis, the company began the process of notifying individuals whose data was confirmed to be involved. To mitigate the potential harm to victims, Miami Management is offering twelve months of complimentary identity protection and credit monitoring services administered by Epiq. This protection package includes essential safeguards such as credit monitoring, dark web surveillance to detect the sale of personal information, identity restoration assistance, and a $1 million identity theft insurance policy. Furthermore, the company is re-evaluating and enhancing its internal security policies, procedures, and technological tools to fortify its defenses against future attacks. Affected parties were strongly advised to enroll in the provided services, vigilantly monitor their financial accounts for suspicious activity, and consider placing a fraud alert or credit freeze with the major credit bureaus—Equifax, Experian, and TransUnion. This incident underscored the critical need for proactive consumer vigilance in the face of escalating cyber threats.
