On average, 4,000 ransomware attacks occurred per day in 2016, according to a report from the FBI. Diving deeper, ransomware attacks on businesses have become more frequent as well. Between January and September 2016, ransomware attacks on business increased from once every two minutes to once every 40 seconds, according to Kaspersky. Over the last 12 months, the levels of cyber activity continue to increase month on month, as have the sophistication of attacks, but in just the four days after the WannaCry attack, the volumes of malicious activity increased 400% over the previous month.
