Alarms maker Verisure flags data breach at partner

STOCKHOLM (Reuters) -Swedish alarms maker Verisure said on Friday it had recently detected unauthorised third-party access concerning data stored with an external billing partner’s system.

Shares in the security group, which was listed on the Stockholm bourse on October 8, were down 4% at 1152 GMT.

Verisure said in a statement that the breach affected its brand Alert Alarm, which currently has fewer than 6,000 customers.

Verisure said its investigation had so far found that the affected data was limited to names, addresses, email addresses, and social security numbers of around 35,000 current and former Alert Alarm customers in Sweden.

"We continue to work with expert advisors and have notified both the police and the relevant authority," it said.

Verisure added that there was so far no evidence of compromise within its own network or systems.
