A1 Hrvatska Discloses Breach

Croatian phone carrier A1 Hrvatska has disclosed a data breach that has impacted roughly 200,000 people.

Threat actors had access to sensitive personal information of the customers, including names, personal identification numbers, physical addresses, and telephone numbers. Threat actors did not access online accounts and financial information was not exposed. At this time the phone carrier did not disclose details about the security breach.

Dspite advanced protection measures and the constant raising of the level of security, a security incident occurred related to one of the user databases, which compromised part of the personal data of part A1 of users. Intensive work is being done to establish all the facts related to the security incident, and so far computer forensics has determined that potentially compromised data are less than 10 percent of A1 users.

Computer forensics experts team has been hired to help the investigation and is notifying law enforcement and impacted customers.

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.
