GDLockerSec claims data breach against Shihka

The threat actor known as GDLockerSec has officially listed the domain www.shihka.com.hk on its dedicated leak site. According to the announcement made on January 24, 2025, the group claims to have successfully exfiltrated data belonging to the organization. This development follows a common pattern observed in modern cyberattacks where threat actors utilize leak sites to pressure victims by threatening to release sensitive information.

The incident, which the group claims occurred on January 24, 2025, involves the publication of data they assert is linked to the target. While the listing has been made public on the group's platform, the specific nature of the breach and the exact contents of the stolen files remain unconfirmed by the victim. This type of activity is often associated with double extortion tactics, where attackers not only encrypt an organization's systems but also steal data to use as leverage during ransom negotiations.

Details of the claimed data exfiltration

The GDLockerSec group has provided limited information regarding the volume and nature of the data they claim to have stolen. According to the group's announcement, the total size of the claimed data is approximately 10MB. The group has shared a screenshot on their leak site to support their claim, which depicts a directory structure containing a .zip file allegedly containing the leaked information.

Despite the visual evidence provided by the threat actor, the specifics of the file contents remain unknown. The listing does not provide any details regarding the specific types of files or the nature of the information contained within the .zip archive. The listing names no specific data types.

The organization profile

Shihka is a textile and apparel company based in Hong Kong. The company operates in the design, manufacturing, and supply of various clothing products. Given its role in the supply chain, the organization's digital assets are critical to its operational functions.

Implications and potential risks

This incident suggests that the organization's digital assets may have been exposed to unauthorized access. While the content of the leaked data remains unclear, the exposure of even a small amount of data can have negative implications for the organization's operational continuity and customer trust. Furthermore, because Shihka is based in Hong Kong, any potential data breaches may be subject to local data protection regulations.

The group responsible, GDLockerSec, has limited public information available regarding their identity or specific motivations, making it difficult to make definitive predictions about their future actions. However, such breaches often carry secondary risks. The leaked data, if authentic, could potentially be used for identity theft or targeted phishing attacks against the organization or its partners.

In general, organizations facing such threats often focus on strengthening their defensive posture through several key steps. These typically include implementing robust multi-factor authentication, maintaining regular offline backups, and conducting thorough employee training to recognize phishing attempts. Monitoring network traffic for unusual exfiltration patterns is also a common defensive measure used to detect unauthorized access before data can be published on leak sites.
