Salad Days Under Siege: OKJ Group Faces Ransomware Threat from Thegentlemen

On a quiet morning in Chiang Mai, the digital storefront of Thailand’s beloved healthy food chain OKJ Group was thrust into the crosshairs of cybercrime. The notorious ransomware collective known as Thegentlemen has claimed responsibility for compromising the company’s systems, marking the public debut of OKJ Group on their victim list. As the aroma of fresh salads and organic produce wafts through their restaurants, a far less wholesome drama brews online - one that could have serious consequences for the company’s reputation, operations, and thousands of health-conscious customers.

Fast Facts

• OKJ Group, operator of the "Oh Ka Jhu" restaurant chain, was founded in 2014 and went public in October 2024.
• The company is known for its focus on organic produce and health-focused meals across Thailand.
• Thegentlemen, a ransomware group, has claimed OKJ Group as its latest victim.
• OKJ Group operates through restaurants, delivery kitchens, kiosks, and supermarkets.
• The nature and extent of the data breach remain undisclosed at this time.

Ransomware on the Menu: What Happened?

Thegentlemen, a cybercriminal group with a growing track record of high-profile extortion campaigns, has added OKJ Group to its roster of victims. The group typically infiltrates corporate networks, encrypts sensitive data, and demands payment in exchange for unlocking files and keeping stolen information from being leaked online. While details remain scarce, the inclusion of OKJ Group on Thegentlemen’s leak site signals a successful breach - potentially exposing customer data, internal documents, and trade secrets.

OKJ Group is no ordinary business target. Since its founding a decade ago, the company has cultivated a loyal following for its health-forward ethos and transparency around organic sourcing. Its IPO in October 2024 made it a fixture on the Stock Exchange of Thailand, raising its profile - and, perhaps, its appeal to cybercriminals seeking high-impact victims. The company’s omnichannel presence, spanning full-service restaurants, delivery operations, kiosks, and supermarket partnerships, means the potential fallout from a cyberattack could be widespread, disrupting not only corporate functions but also supply chains and customer trust.

Ransomware attacks like this one are rarely just about money. They are about leverage - criminals betting that the cost of data loss, reputational damage, and operational downtime will force companies to pay up. For OKJ Group, the stakes are especially high: customer loyalty is built on trust, and a breach could taint the brand’s wholesome image.

What’s Next for OKJ Group?

As of now, OKJ Group has not released a public statement about the incident. The company faces a critical juncture: whether to negotiate with cybercriminals or risk sensitive data being leaked. Meanwhile, cybersecurity experts warn that the food and beverage sector is increasingly in the crosshairs, as attackers look for soft targets with high-value data and limited defenses. For Thailand’s organic food champion, the coming days will test not just its cyber resilience, but its commitment to the trust of its customers and investors.
