The threat actor is demanding a ransom of 450,000 USD in exchange for the data. The announcement specifies that the total volume of the data involved in this alleged breach is 50 GB.

Organization profile

China Harbour Engineering Company (CHEC) is a major Chinese engineering and construction firm. It specializes in large-scale infrastructure projects such as ports, railways, bridges, and airports. Given the scale of these projects, the organization operates within a critical infrastructure context.

Potential impact and industry considerations

Public information about the devman group remains limited. This alleged data breach may affect the organization's operational continuity and lead to a loss of commercial reputation. If the leaked data includes employee or customer information, there may be a risk of identity theft or targeted phishing attacks against the affected individuals.

Given the sector and region in which the organization operates, data security breaches may result in legal and regulatory consequences. Considering the use of double extortion tactics, the publication of the data may increase secondary risks. Double extortion is a common ransomware tactic where attackers not only encrypt an organization's data but also steal it, threatening to leak it publicly if the ransom is not paid. This adds a layer of pressure beyond simple operational disruption.

For organizations operating in the transportation and infrastructure sectors, maintaining robust cybersecurity postures is essential. Common defensive steps often include implementing multi-factor authentication, maintaining regular offline backups, and conducting regular security awareness training for employees to prevent initial access via phishing. Furthermore, monitoring for unauthorized data exfiltration can help mitigate the impact of such attacks before data is published on leak sites.
