By the end of 2017, basically anyone doing any kind of cybercrime was also likely dabbling in cryptomining. This includes compromised websites serving drive-by mining code, a significant increase of miners through malicious spam and exploit kit drops, and adware bundlers pushing miners instead of toolbars. Cryptomining is out of control.Īlongside a sudden cryptocurrency craze, bad actors have started utilizing cryptomining tools for their own profit, using victim system resources in the process. The second half of the year also marked an average of 102 percent increase in banking Trojan detections. We saw an increase of 40 percent in hijackers and 30 percent in spyware detections in 2017. With ransomware slowly going out of favor, criminals pivoted to banking Trojans, spyware, and hijackers in 2017 to attack companies instead. What they can’t hold for ransom, criminals will steal instead.
However, development of new families and tactics for delivery slowed way down, especially in the last quarter of the year. Ransomware detections were up 90 and 93 percent for businesses and consumers respectively in 2017, with several splashy outbreaks accounting for the majority of the increase in rates. Some of our key takeaways include: Ransomware volume was up in 2017, but trending downward. We dove into the exponential increases of malware volume and severity year-over-year, as well as trends in high-impact threats, such as ransomware and cryptomining. In our 2017 State of Malware report, we examined attack methods, malware developments, and distribution techniques used by cybercriminals over the last 12 months. What we came up with was a more complete picture of the 2017 threat landscape that showed us just how much can change in a year. In aiming to make sense of the madness, we gathered information from our data science, research, and intel teams throughout the year, checking in on trends, the rise and fall of malware families, distribution methods, and more.
Last year was full of twists and turns in the cybercrime world, with major outbreaks, new infection methods, and the evolution of the cryptocurrency crime industry. 2017 was a tumultuous year in politics, media, gender, race-and cybersecurity didn’t beat the rap.
