RansomHouse Ransomware Attack on Guangdong Nanguo Pharmaceutical Co.

Guangdong Nanguo Pharmaceutical Co., Ltd., a key player in the Chinese pharmaceutical industry, has recently fallen victim to a ransomware attack allegedly orchestrated by the notorious RansomHouse group. This breach, discovered on November 26, involved a substantial data leak of approximately 1.4TB, potentially compromising sensitive information and disrupting the company's operations.

Company Profile and Industry Standing

Established in 1977, Guangdong Nanguo Pharmaceutical is a prominent pharmaceutical company based in Guangdong Province, China. The company specializes in the development, manufacturing, and marketing of a diverse range of pharmaceutical products, with a strong emphasis on traditional Chinese medicine (TCM) and modern pharmaceuticals. Employing around 100 people, the company is known for integrating traditional medicinal practices with modern techniques, appealing to a growing consumer interest in natural health solutions. This unique approach has allowed Guangdong Nanguo Pharmaceutical to stand out in a competitive market.

Vulnerabilities and Attack Overview

The attack on Guangdong Nanguo Pharmaceutical highlights vulnerabilities that can be exploited by sophisticated threat actors like RansomHouse. The company's focus on innovation and digital transformation, while beneficial for growth, may have inadvertently exposed it to cyber threats. The breach has affected the company's digital intelligent production base, posing challenges in safeguarding data integrity and resuming normal production activities.

RansomHouse: A Distinctive Ransomware Group

RansomHouse distinguishes itself in the cybercrime landscape through its unique approach to extortion. Operating under a Ransomware-as-a-Service model, the group employs dual-extortion tactics, focusing on data exfiltration rather than encryption. This method allows them to maintain a lower profile and extend their presence within compromised networks. RansomHouse is known for exploiting vulnerabilities and using sophisticated tools like PowerShell and Mimikatz to infiltrate systems. Their operations are further characterized by the use of Tor-based communication channels and a dark web leak site for negotiations and data publication.

Potential Penetration Methods

RansomHouse likely penetrated Guangdong Nanguo Pharmaceutical's systems by exploiting known vulnerabilities or compromised credentials. The group's expertise in data exfiltration and obfuscation techniques, such as using 7-zip, suggests a well-coordinated attack strategy. This incident underscores the importance of effective cybersecurity measures to protect against evolving threats from groups like RansomHouse.
