Ransomed group claims compromise of Sony.com systems

The threat actor known as Ransomed has announced that it has successfully compromised the systems belonging to SONY.COM. According to the announcement posted on a leak site on September 26, 2023, the group is now offering the allegedly exfiltrated data for sale on the open market.

The group's motivation for the public listing appears to be a refusal by the institution to meet their financial demands. The threat actor states that they are proceeding with the sale of the data because the organization has refused to pay a ransom. The announcement provided by the group includes links to a file tree and samples of the data they claim to have exfiltrated from the organization's network.

Details of the alleged data exfiltration

While the group has provided a file tree and samples to support their claims, the specific contents of the leaked information remain unclear. No detailed information regarding the specific content of the leaked data has been provided by the threat actor, and no screenshots were included in the announcement to verify the nature of the files.

The listing names no specific data types that have been compromised.

Risk assessment and industry implications

This incident may pose significant risks to the institution's operational continuity and data privacy. Depending on the nature of the leaked data, the exposure of employee or customer information could lead to identity theft and targeted phishing attacks. Furthermore, the institution may face legal obligations under Japan's Act on the Protection of Personal Information (APPI).

Public information regarding the Ransomed group remains limited. However, the group's method of selling data after a failed ransom negotiation may be considered part of a double extortion strategy. In a double extortion scenario, attackers not only encrypt an organization's data to disrupt operations but also steal sensitive information to threaten the victim with its public release or sale.

For organizations operating within the technology sector, such incidents highlight the importance of robust data protection frameworks. Defensive measures typically include implementing strict access controls, maintaining comprehensive logging to detect unauthorized exfiltration, and ensuring compliance with regional data protection regulations. Protecting against these types of threats requires a multi-layered approach to security to mitigate the impact of potential data exposure and ensure business continuity.
