Manatee Air Ransomware Claim by m3rx (May 2026)

Claim Summary

The ransomware group known as “m3rx” has allegedly claimed responsibility for a cyberattack against Manatee Air Heating & Cooling Inc, a Florida-based HVAC services company operating under the domain manateeair.com. According to a post on the group’s leak site dated May 3, 2026, the threat actor claims to have stolen data from the organization, which has been providing HVAC services in Manatee and Sarasota counties since 1988. The group’s post includes the company’s phone number (+1 9417582323) and a description of Manatee Air’s services, but does not specify the volume or type of data allegedly exfiltrated. The claim has not been independently verified by Yazoul Security, and no official confirmation from Manatee Air has been observed at the time of writing.

Threat Actor Profile

The group “m3rx” is a relatively obscure ransomware operation with limited public exposure. Based on available intelligence, the group has a small number of known victims, and its tools, tactics, and procedures (TTPs) are not well-documented in open-source research. No public YARA rules or specific detection guidance are currently available for m3rx. The group’s credibility is difficult to assess due to the lack of a proven track record; it is possible that m3rx is a new or rebranded operation, or a smaller group attempting to gain notoriety by targeting small-to-medium businesses. Ransomware groups with limited history often exaggerate claims to pressure victims into payment, and this should be considered when evaluating the threat.

Alleged Data Exposure

The m3rx group claims to have stolen data from Manatee Air, but the post provides no details on the nature or volume of the information. The group’s leak site description includes the company’s phone number and a general overview of its services, but no samples, file lists, or evidence of data exfiltration have been published. This lack of specificity is a common tactic used by ransomware groups to create uncertainty and pressure victims, especially when the actual data breach may be minimal or fabricated. Without confirmation from Manatee Air or independent forensic analysis, the extent of any data exposure remains unverified.

Potential Impact

If the claim is accurate, Manatee Air could face operational disruptions, reputational damage, and potential regulatory scrutiny. As a provider of HVAC services, the company likely stores customer contact information, service records, and possibly financial data. Exposure of such information could lead to phishing attacks, identity theft, or fraud targeting customers. Additionally, the company’s reliance on emergency services and fast turnaround times could be compromised if internal systems are affected. However, given the group’s unknown credibility, the actual impact may be limited.

What to Watch For

• Official Statements: Monitor Manatee Air’s website and social media for any acknowledgment of a security incident.
• Customer Communications: Watch for phishing emails or suspicious messages that may reference the alleged breach.
• Leak Site Activity: Check if m3rx publishes additional data or evidence to substantiate its claim.
• Regulatory Notifications: If the breach is confirmed, Manatee Air may be required to notify affected parties under U.S. data breach laws.
