A spokesperson for the National Cyber Security Centre said:
“Earlier this week we were made aware of a global cyber incident that was reported to be ransomware.
“While managing the impact to the UK, the NCSC’s experts have found evidence that questions initial judgements that the intention was to collect a ransom.
“We are investigating with the NCA and industry whether the intent was to disrupt rather than for any financial gain.
“We recognise the impact this attack has had on affected businesses. If you think you have been a victim you should report to Action Fraud by calling 0300 123 2040.”
