Overview
- Organisers disclosed the breach on Thursday that occurred at Cloudbear, a supplier used by research firm Abbi Insights to process post‑event surveys for De Vrienden van Amstel LIVE and Amstel LIVE in de Kroeg.
- Reportedly involved data include names, e‑mail addresses, phone numbers, gender, birthdates and postcodes for Ahoy visitors and likely first names and e‑mails for the kroeg events, while organisers say no bank details or passwords were exposed.
- It remains unknown whether the data were actually viewed, copied or misused, and Abbi Insights and Cloudbear are working with the organiser to carry out a forensic investigation.
- Affected visitors have been notified by e‑mail and warned to watch for phishing by e‑mail, SMS, WhatsApp or phone and to avoid clicking links or sharing verification codes.
- The incident has been reported to the Autoriteit Persoonsgegevens, and next steps include confirming whether data were exfiltrated, deciding remedial measures and reviewing vendor security because third‑party suppliers increase supply‑chain risk.
