The WannaCry malware remains a serious security threat, two years after it first emerged, with ‘hundreds of thousands’ of systems still vulnerable to the exploits that WannaCry used to propagate.
According to researchers from security firm Malwarebytes, a total of 4,826,682 WannaCry detections have been identified since its first attack in May 2017.
On 12 May 2017, WannaCry encrypted hundreds of thousands of systems in a matter of hours across more than 150 countries. It was the first time that ransomware had infected so many PCs so quickly, and in so many countries.
Although, WannaCry was neutralised by Marcus Hutchins after discovering a ‘kill switch’ inadvertently left in the code, variants of WannaCry still exist and continue to infect systems, according to Malwarebytes.
In its global list of countries where WannaCry variants have been detected over the past two years, India is at the top with 727,883 WannaCry infections, followed by Indonesia (561,381), the US (430,643), Russia (356,146) and Malaysia (335,814).
In Europe, France is the most affected, with 138,182 detections reported since the second quarter of 2017.
