Solaria targeted by thegentlemen ransomware group

• Ransomware group: thegentlemen
• Country: Indonesia
• Sector: Agriculture and Food Production
• Announcement date: September 30, 2026

The threat group known as thegentlemen has issued a data leak announcement claiming to have compromised the systems of the Indonesian restaurant chain Solaria. This announcement, published on a ransomware leak site, suggests that the organization's digital assets may be at risk following a claimed attack that occurred on September 29, 2026.

The claimed attack and leak announcement

According to the announcement published on September 30, 2026, the threat actor known as thegentlemen alleges that they have successfully gained access to the internal systems of Solaria. The group claims to have obtained various data during this unauthorized access. This type of announcement is a common tactic used by ransomware groups to pressure victims into meeting specific demands.

In many modern cyberattacks, threat actors utilize a method known as double extortion. In these scenarios, attackers do not merely encrypt a company's data to disrupt operations; they also steal sensitive information before the encryption process begins. By threatening to leak this stolen data on public forums or dedicated leak sites, the attackers aim to increase the pressure on the organization, potentially leading to secondary data breaches or increased leverage during negotiations.

Details regarding the leaked data

While the threat group has officially announced the breach, they have not provided specific details regarding the nature of the information they claim to have stolen. At this time, no screenshots or detailed information regarding the specific types of data involved have been provided by the group. Furthermore, the announcement does not specify the total volume of data or the exact number of files that were allegedly compromised.

About Solaria

Solaria is a major family restaurant chain based in Indonesia. Founded in 1991, the company operates under PT Sinar Solaria and manages a vast network of over 200 outlets spread across 55 different cities. Unlike many other large food chains, Solaria maintains all of its locations as company-owned, operating without the use of franchises.

The restaurant specializes in affordable Asian-Indonesian comfort food. It is widely recognized for its large portions and primarily serves a customer base consisting of middle-class families and shoppers located in malls.

Impact assessment and industry implications

This incident may create negative impacts on Solaria's operational continuity and customer trust. Depending on the actual content of the leaked data, there is a risk that identity theft or targeted phishing attacks may be observed if the personal information of employees and customers is exposed. Because the organization is based in Indonesia, this event may trigger legal processes under local data protection regulations.

For organizations operating within the agriculture and food production sectors, such incidents highlight the importance of robust cybersecurity frameworks. When a threat group's information is limited, as is the case with thegentlemen, it can be difficult for organizations to assess the full scope of the threat immediately. This uncertainty often increases the pressure on the victimized company.

To mitigate risks associated with such breaches, organizations typically focus on several defensive pillars: data encryption to ensure that even if data is stolen, it remains unreadable; multi-factor authentication (MFA) to prevent unauthorized access to systems; and regular offline backups to ensure operational continuity in the event of a ransomware encryption event. Furthermore, maintaining strict adherence to local data protection laws is essential for managing the legal and reputational fallout that follows a confirmed data leak.
