www.jhayber.com Listed by ransomhub Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target mid-sized commercial firms across Europe, using data theft and public leak-site listings as leverage. In this landscape, the Spanish sportswear company operating at www.jhayber.com was listed by the RansomHub group on 2 March 2025. The listing asserts that internal files were exfiltrated during a ransomware attack; the number of people affected remains unknown and further technical detail has not been made public.

Because the claim rests solely on the group's own site and no independent confirmation of the volume or content of any stolen material has been released, the incident is best treated as an unverified assertion that still warrants attention from customers, staff and partners who may have shared information with the firm.

Inside the incident

Public reporting of the event is limited to the RansomHub leak-site entry dated 2 March 2025. That entry names www.jhayber.com and states that internal files were exfiltrated in a ransomware attack. No information has been disclosed about the date of the initial intrusion, the attack vector, the volume of data taken, or whether any systems were encrypted. The number of individuals whose data may have been involved is recorded as unknown. No ransom demand figure or negotiation timeline has been published by either the company or the group.

The group behind it: ransomhub

RansomHub is a ransomware-as-a-service operation that became active in early 2024 after the disruption of several earlier groups. It typically recruits affiliates who gain initial access, deploy the ransomware payload, and then exfiltrate data before encryption. The group maintains a public leak site on which it posts victim names and sample files if payment is not received, a classic double-extortion model. Prior listings have covered organisations in manufacturing, retail and professional services across multiple continents. In the present case the group claims that internal files belonging to www.jhayber.com were taken; that claim has not been independently verified.

About www.jhayber.com

Jhayber is a Spanish sportswear manufacturer with more than four decades of activity. It designs and sells footwear, clothing and accessories intended for men and women engaged in sport and fitness. Like most consumer-goods companies of its size, it maintains customer order records, loyalty or marketing databases, employee personnel files, supplier contracts and internal operational documents. A breach at such an organisation can therefore affect both private individuals who have purchased products and the business relationships that keep the supply chain running.

The information in question

The only data category named in the public listing is “internal files exfiltrated in ransomware attack.” No further breakdown—customer records, financial documents, employee data or otherwise—has been supplied. Organisations in the apparel sector commonly hold names, addresses, payment-card details, purchase histories, staff payroll information and proprietary design or inventory files. Whether any of those categories were among the material claimed by RansomHub remains unconfirmed.

The real-world impact

If personal data were included, affected individuals face the ordinary risks of phishing, credential stuffing or identity fraud that follow any unauthorised disclosure. For the company itself, the listing can disrupt operations, erode customer trust and trigger regulatory notification duties under European data-protection rules. Because the scale of the alleged exfiltration is unknown, the precise severity of these consequences cannot yet be measured. Staff and customers are advised to treat any unexpected communication that references Jhayber accounts or orders with caution until more information emerges.

Were you affected?

Anyone who has purchased from Jhayber, worked for the company or supplied goods to it should consider the following practical steps:

• Monitor bank and card statements for unfamiliar charges.
• Change passwords used on the Jhayber site or related accounts, especially if the same credentials appear elsewhere.
• Enable multi-factor authentication wherever it is offered.
• Watch for phishing messages that claim to come from Jhayber or reference an alleged breach.
• Run a free exposure scan of your email address against known breach data sets to see whether your details have already appeared in other incidents.

Public detail on this particular listing remains limited; further official statements from the company or law-enforcement agencies should be monitored as they become available.
