Fourlis Group, the retail operator responsible for IKEA stores across Greece, Cyprus, Romania, and Bulgaria, has revealed that a ransomware attack targeting its systems in late November 2024 led to significant financial losses. The cyber incident, which coincided with the busy Black Friday shopping period, disrupted critical parts of the business and caused damages estimated at €20 million (around $22.8 million).
The breach initially surfaced as unexplained technical problems affecting IKEA’s e-commerce platforms. Days later, on December 3, the company confirmed that the disruptions were due to an external cyberattack. The attack affected digital infrastructure used for inventory restocking, online transactions, and broader retail operations, mainly impacting IKEA’s business. Other brands under the Fourlis umbrella, including Intersport and Holland & Barrett, were largely unaffected.
According to CEO Dimitris Valachis, the company experienced a loss of approximately €15 million in revenue by the end of 2024, with an additional €5 million impact spilling into early 2025. Fourlis decided not to comply with the attackers’ demands and instead focused on system recovery through support from external cybersecurity professionals. The company also reported that it successfully blocked a number of follow-up attacks attempted after the initial breach.
Despite the scale of the attack, an internal investigation supported by forensic analysts found no evidence that customer data had been stolen or exposed. The incident caused only a brief period of data unavailability, which was resolved swiftly. As part of its compliance obligations, Fourlis reported the breach to data protection authorities in all four affected countries, reassuring stakeholders that personal information remained secure.
Interestingly, no known ransomware group has taken responsibility for the attack. This may suggest that the attackers were unable to extract valuable data or are holding out hope for an undisclosed settlement—though Fourlis maintains that no ransom was paid.
The incident highlights the growing risks faced by digital retail ecosystems, especially during peak sales periods when system uptime is critical. As online platforms become more central to retail operations, businesses like Fourlis must invest heavily in cybersecurity defenses. Their experience reinforces the importance of swift response strategies, external threat mitigation support, and robust data protection practices to safeguard operations and maintain customer trust in the face of evolving cyber threats.
