Cyber attack: Europol says it was unprecedented in scale
cyber attack that struck organisations around the world, including the NHS, was “unprecedented” in scale, Europe’s police agency says.
Europol also warned a “complex international investigation” was required “to identify the culprits”.
Ransomware encrypted data on at least 75,000 systems in 99 countries on Friday. Payments were demanded for access to be restored.
European countries, including Russia, were among the worst hit.
Although the spread of the malware – known as WannaCry and variants of that name – appears to have slowed, the threat is not yet over.
Europol said its cyber-crime team, EC3, was working closely with similar teams in the affected countries to “mitigate the threat and assist victims”.
In the UK, the head of the cyber security agency said experts were “working around the clock” to restore the systems of some 45 NHS organisations in England and Scotland that were hit by the attack.
The attack left some hospitals and GPs unable to access patient data, and led to the cancellation of operations and medical appointments.
