The data of a maximum of 22,000 people who participated in research for the Friends of Amstel Live are on the street.
This is reported by a spokeswoman for Heineken, which has had research carried out by market researcher Blauw among visitors to the event. The beer group has now informed visitors.
Scammers can use names and contact details for ‘phishing’, where they pose as someone else in emails or apps to steal sensitive information or passwords, for example.
According to Blauw, a total of fourteen companies have been affected. The market researcher received a message on Friday that an unauthorized person had access to the network of the software supplier. On Monday, this supplier confirmed that data had actually been stolen. The company is still investigating exactly which data was stolen or viewed by unauthorized persons. Access to the personal data has now been closed.
VodafoneZiggo, Blauw and the NS have reported this to the Dutch Data Protection Authority (AP). Blauw does not want to say who the software supplier was or which companies were affected. Albert Heijn, Etos, bol.com and Vattenfall are also clients of Blauw, but have stated that they have not been affected by the data leak. The same applies to Efteling, Marktplaats, Thuisbezorgd.nl and ESPN.
