Robert G. Dashiell, Jr., P.E., Inc. targeted by Radar ransomware group

• Ransomware group: Radar
• Country: United States
• Sector: Professional Services
• Announcement date: September 10, 2025

The threat actor group known as Radar has claimed responsibility for a significant data breach involving the engineering firm Robert G. Dashiell, Jr., P.E., Inc. According to an announcement posted on a leak site on September 10, 2025, the group asserts that they have successfully exfiltrated a massive volume of sensitive information belonging to the organization.

The details of the alleged attack

The Radar group published their announcement on September 10, 2025, claiming to have exfiltrated data from Robert G. Dashiell, Jr., P.E., Inc. The threat actor asserts that they have obtained internal company documents and various confidential files through their operation. While the group has made these claims publicly, it is important to note that public information regarding this specific group remains limited.

The attack appears to follow the patterns often seen in modern cyber extortion campaigns. In such scenarios, threat actors typically gain access to a network and move laterally to identify high-value targets, such as sensitive documents and databases. Once the data is secured, the attackers often employ double extortion tactics. This method involves not only encrypting the victim's systems to disrupt operations but also threatening to release stolen data on public leak sites to increase the pressure on the organization to pay a ransom.

The scope of the claimed data leak

The scale of the alleged breach is substantial, with the group claiming to have leaked approximately 500 GB of data. The content of the allegedly leaked data is highly sensitive and encompasses a wide range of personal, financial, and corporate information. Based on the group's claims, the stolen information includes:

• Employee private data
• Client information
• Confidential contracts
• Projects
• Orders
• IDs
• SSN
• Email conversations
• Bank statements
• Tax bills
• Signatures

The presence of such diverse data types, ranging from Social Security Numbers to bank statements and signatures, suggests a deep penetration into the organization's internal file systems and communications.

About Robert G. Dashiell, Jr., P.E., Inc.

Robert G. Dashiell, Jr., P.E., Inc. is a professional engineering firm based in Norfolk, Virginia. The company specializes in providing various engineering services to its clients.

Risk assessment and organizational implications

The nature of the allegedly leaked data may pose a high risk of identity theft and financial fraud for the firm's employees and clients. Because the stolen information includes highly sensitive identifiers like SSNs and bank statements, the potential for misuse by malicious actors is significant. Furthermore, as a US-based entity, the breach may lead to legal consequences under state-level data protection laws and federal regulations.

Beyond the immediate legal and financial risks, the sensitivity of the shared data could damage the firm's commercial reputation and potentially serve as a basis for targeted phishing attacks against third parties. When attackers possess email conversations and project details, they can craft highly convincing social engineering attacks against the firm's partners or clients.

In such high-stakes scenarios, organizations in the professional services sector can take several defensive steps to mitigate risks. Implementing robust multi-factor authentication (MFA) across all remote access points is a fundamental security measure. Additionally, maintaining strict network segmentation can help prevent attackers from moving from general office environments to sensitive data repositories. Regular, offline backups and comprehensive employee training on recognizing phishing attempts are also vital components of a modern cybersecurity posture. As the group may be attempting to exert pressure on the firm's operational continuity through these leaks, maintaining a resilient incident response plan is essential for any organization facing such threats.
