More than half of European firms admit business disruption and data loss due to cyber attacks in the past 24 months, with UK firms among the most targeted, a survey shows.

One in five IT decision-makers claimed cyber attackers left no clue to their identity, while 54% said they had faced at least one attack in the past two years that resulted in some sort of disruption, a survey has revealed.

This disruption was in the form of service disruption (31%), data integrity issues (18%) and data loss (15%), according to the poll of nearly 2,000 European firms by security firm Kaspersky Lab.

Organisations in the UK and Spain faced the highest risks, the survey found, with 64% of respondents confirming they had been hit by cyber attacks in the past two years.
