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

Ransomware groups continue to target mid-sized organisations across education and professional services, often listing victims on leak sites after claiming to have stolen data. On 21 February 2025, the Guadeloupe-based training provider guadeloupeformation.com appeared on a listing attributed to the RansomHub group. Public detail remains limited, yet the claim of internal-file exfiltration raises clear questions for anyone who has dealt with the organisation as a trainee, employee or partner.

What is known so far is sparse: the group asserts that internal files were taken in a ransomware attack, the number of people affected is unknown, and no further technical or financial particulars have been released. For individuals whose contact or training records may sit in those systems, the practical concern is whether personal information has left the organisation’s control.

Inside the incident

According to the available record, guadeloupeformation.com was listed by the RansomHub ransomware group on 21 February 2025. The listing characterises the event as a ransomware attack in which internal files were allegedly exfiltrated. No confirmed figure for the number of people affected has been published, and the precise method of intrusion, the volume of data taken, and any ransom demand remain undisclosed. The organisation itself has not issued a public technical statement that would corroborate or expand on the group’s claim. In short, the only concrete public marker is the leak-site listing itself and the assertion that internal files left the network.

The group behind it: ransomhub

RansomHub is a ransomware-as-a-service operation that became prominent after the disruption of earlier groups such as ALPHV/BlackCat. It typically recruits affiliates who gain initial access, deploy encryption tools, and exfiltrate data before posting victims on a dedicated leak site if payment is not made. The model relies on double extortion: encryption of systems combined with the threat of public data release. RansomHub has previously claimed attacks against organisations in healthcare, manufacturing, education and professional services across multiple continents. Its listings are claims of compromise rather than independently verified disclosures; in this case the group claims that guadeloupeformation.com suffered an attack involving the theft of internal files. No additional statements attributed specifically to this victim beyond that listing appear in the public record.

About guadeloupeformation.com

Guadeloupeformation.com operates as a professional training institution based in Guadeloupe, a French overseas region in the Caribbean. It offers courses in management, communication, sales, health and safety, computing and foreign languages, aiming to equip working adults with practical skills. Organisations of this type routinely maintain records of course participants, instructors, administrative staff and corporate clients. Those records can include names, contact details, professional backgrounds, payment information and, in some cases, identity documents required for certification or funding. Because the institution sits at the intersection of education and workforce development, a breach can affect both private individuals seeking career advancement and the employers who sponsor their training.

What was likely exposed

The only data category named in the public facts is “internal files exfiltrated in a ransomware attack.” No inventory of file types, databases or specific personal fields has been released. Professional training providers typically hold enrolment forms, attendance logs, certificates, invoices, staff personnel files and correspondence with partner companies. Such material can contain names, addresses, email addresses, telephone numbers, dates of birth, professional qualifications and, occasionally, banking or identity details. Whether any of those categories were present in the files claimed by RansomHub remains unconfirmed. Until the organisation or an independent investigation publishes a verified list, the exact contents must be treated as unknown.

Why it matters

For individuals, the principal risk is that personal or professional information could be used for targeted phishing, identity fraud or social-engineering attempts that reference genuine training history. Even limited contact data can help attackers craft convincing messages. For the organisation, the consequences include potential regulatory scrutiny under French and European data-protection rules, disruption of training schedules, and loss of trust among corporate clients who rely on the provider for compliance or skills programmes. Because the number of people affected is unknown, the scale of any secondary harm cannot yet be measured; the uncertainty itself is a practical problem for anyone who has interacted with the institution.

If your data was in this claimed breach

If you have enrolled in courses, worked for, or otherwise shared personal information with guadeloupeformation.com, treat the listing as a signal to act cautiously. Change passwords associated with any accounts that used the same email address, enable multi-factor authentication where available, and monitor financial and government correspondence for unexpected activity. Be sceptical of unsolicited messages that reference training programmes or request urgent verification. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets; such a scan provides an additional, independent indicator of exposure beyond this single incident.
