In March 2018, Symantec unveiled its annual Internet Security Threat Report (ISTR). Two of the main takeaways are that the types of threats are broadening, and already popular attacks are seeing significant increases in execution. The report notes an 8,500 percent increase in detections of coinminers on endpoint computers in 2017, and a 600 percent increase in overall IoT attacks. While the average ransom dropped in value, the number of new ransomware variants increased by 46 percent.
