2017 has been a year of global ransomware spread, especially with the global outbreak of the Eternal Blue ransomware worm (WannaCry) in May and the subsequent Petya virus, which was prevalent in Ukraine and elsewhere, bringing attention to ransomware to an unprecedented level.
But the ransomware virus didn't fade with the passing of 2017. Nearly a third of the way through 2018, ransomware attacks continue unabated, and for now, ransomware remains a major cybersecurity cancer, and its dangers still cannot be ignored.
Ransomware active throughout 2017: over 5 million computers attacked
According to the 2017 Ransomware Threat Situation Analysis Report released by the 360 Internet Security Center, a total of 183 new ransomware variants were intercepted by the 360 Internet Security Center on the computer side in 2017. At least 5 million computers across the country have been hit by ransomware attacks, with an average of about 14,000 domestic computers being hit by ransomware every day.
In terms of timing, ransomware attacks peaked at 811,000 in April, with an average of 27,000 computers attacked per day, largely due to the public disclosure of the NSA vulnerability "Eternal Blue" by the Shadow Brokers group, which many ransomware exploited to launch attacks.
