The number of cyberattacks doubled in 2017, with ransomware leading the way.
That’s according to the Online Trust Alliance (OTA), which has named 2017 “the worst year ever in data breaches and cyber-incidents around the world.”
OTA’s Cyber Incident & Breach Trends Report found that skyrocketing ransomware usage resulted in 160,000 cyberattacks. That’s nearly doubled from 82,000 in 2016. And since the majority of cyber-incidents are never reported, the actual number in 2017 could easily exceed 350,000, the firm estimated.
Of those, there were 134,000 ransomware attacks on businesses, nearly doubling that of 2016. In mid-2017 another type of ransomware attack emerged—the ransom denial-of-service (RDoS) attack. In this attack, criminals send an email to domain owners threatening a distributed denial-of-service (DDoS) attack that will make a website inoperable unless a ransom (usually via Bitcoin) is paid.
