Security breach in A1 Croatia
Up to 10% of A1 Croatia clients could be endangered by personal data due to security breaches.
The Croatian operator said in a press release: “Unfortunately, despite advanced protection measures and constant raising of the level of security, there was a security incident related to one of the user databases that compromised part of the personal data of A1 users. Intensive work is being done to establish all the facts related to the security incident, and so far computer forensics has determined that less than 10% of A1 users have potentially compromised data. The data on the screen are name and surname, address, OIB and telephone number. We emphasize that the data on bank cards and accounts are not endangered because they are not available in the specified database. We will directly notify all users whose personal information is potentially compromised.
“A1 Croatia takes this embarrassing situation extremely seriously and immediately after the first signs of suspicion of unauthorized access to the user base immediately and without delay prevented further unauthorized access and took additional protection measures. A criminal complaint was also immediately filed with the Zagreb Police Administration, and information experts were involved in discovering the perpetrators of the crime. Also, the competent institutions HAKOM and AZOP, with which we cooperate intensively, were informed.
“A1 Croatia adheres to the highest security standards and data protection and we will continue to make additional investments in improving the security environment. The recurrence of this security incident is not possible and has not had and will not affect the provision of services to customers.
The operator has concluded that it will inform users in a timely manner of further actions related to this event.
A1 Croatia, formerly known as Vipnet, is part of the A1 Telekom Austria Group.
