The RansomHub ransomware group has claimed responsibility for a cyberattack on Charles Blalock & Sons, Inc., a division of Blalock Companies. This attack underscores the persistent threat posed by ransomware groups targeting the construction sector.
Company Profile and Industry Standing
Blalock Companies, headquartered in Sevierville, Tennessee, is a prominent player in the construction industry, operating primarily in Tennessee and Alabama. The company encompasses several entities, including Charles Blalock & Sons, Inc., Blalock Building Company, and Blalock Ready Mix. Charles Blalock & Sons specializes in earthwork, focusing on excavation, grading, and site preparation. The company employs over 700 individuals and has an estimated annual revenue of $48.5 million.

Attack Overview
RansomHub claims to have infiltrated Charles Blalock & Sons' systems, exfiltrating approximately 150 GB of sensitive data. The attack highlights vulnerabilities in the construction sector, where companies often rely on legacy systems and may lack effective cybersecurity measures. The breach raises concerns about the potential impact on the company's operations and client relationships.
RansomHub's Modus Operandi
RansomHub, a Ransomware-as-a-Service (RaaS) group, emerged in February 2024, quickly establishing itself as a formidable player in the ransomware landscape. The group employs a double extortion strategy, encrypting data and exfiltrating sensitive information to increase ransom demands. RansomHub is known for its speed and efficiency, using advanced encryption techniques and targeting cross-platform systems. The group often exploits vulnerabilities in unpatched systems and employs phishing campaigns to gain initial access.
Potential Vulnerabilities and Penetration Methods
RansomHub likely penetrated Blalock Companies' systems through a combination of phishing and exploiting unpatched vulnerabilities. The construction sector's reliance on legacy systems and potential lack of comprehensive cybersecurity measures make it an attractive target for ransomware groups. RansomHub's use of advanced data exfiltration techniques and intermittent encryption further complicates detection and mitigation efforts.
