Safepay ransomware group lists triangleheatingcooling.com on its leak site

• Ransomware group: Safepay
• Country: United States
• Sector: Retail & E-Commerce
• Announcement date: June 7, 2025

The Safepay ransomware group has announced a data breach involving triangleheatingcooling.com. According to a listing on the group's leak site, the threat actor claims to have exfiltrated a significant volume of data from the organization's systems.

The claimed attack details

The threat actor known as Safepay announced on June 7, 2025, that it has targeted triangleheatingcooling.com. The group has listed a dataset on its leak site, which they claim was obtained from the organization's systems. The group's announcement also included a specific financial detail, stating that the organization has an annual revenue of $5 million.

While the announcement was made in June, the group has claimed the attack occurred on May 16, 2025. This timeline highlights the period between the initial intrusion and the public disclosure on the leak site, a common pattern in ransomware operations where attackers attempt to pressure victims through public exposure.

Data involved in the leak

Regarding the specific content of the leaked information, no specific details regarding the content of the leaked data have been provided, other than the mention of an 8 GB dataset. The listing does not specify the types of files or the nature of the information contained within the volume.

• 8 GB of data

Organization profile

Triangle Heating & Cooling is a company that provides installation, maintenance, and repair services for heating, ventilation, and air conditioning (HVAC) systems for residential and commercial buildings.

Analysis and implications

Given that the Safepay group operates using a double-extortion model, it is assessed that the leaked data may pose a risk of identity theft for the organization's employees or customers. In a double-extortion scheme, attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information to use as leverage, threatening to leak it if the ransom is not paid. This tactic increases the pressure on the victim by targeting their reputation and the privacy of their stakeholders.

The publication of this data could damage the organization's commercial reputation and may also create a foundation for targeted phishing attacks against third parties. When sensitive data is leaked, attackers often use the information to craft highly convincing social engineering campaigns, making it more difficult for individuals to distinguish legitimate communications from fraudulent ones.

Since the organization is based in the US, state-level data breach notification laws and potential legal sanctions may be applicable. Depending on the jurisdiction and the nature of the data, organizations are often required by law to notify affected individuals and regulatory bodies following a confirmed breach.

The fact that the group emerged in late 2024 and does not utilize an affiliate program suggests that its operational structure may be under centralized control. This differs from many other ransomware-as-a-service (RaaS) models where various affiliates carry out attacks under a central brand. A centralized structure can sometimes indicate a more focused and disciplined operational approach.

Defensive considerations

Organizations in the service and retail sectors can take several steps to mitigate the risks associated with such attacks. Implementing robust data encryption for data at rest and in transit can help protect sensitive information from being useful even if it is exfiltrated. Furthermore, maintaining strict access controls and multi-factor authentication can reduce the likelihood of an unauthorized actor gaining access to internal systems.

Regularly updating software and monitoring network traffic for unusual patterns can also assist in the early detection of unauthorized data movement, which is a critical component of preventing large-scale data exfiltration.
