We were also intently monitoring which botnet will replace the previous kingpin Emotet in Q3. Another novel research was the discovery of the Crackonosh crypto stealer that earned more than $2 million USD to its operators. To give you a sneak peak of the report: My colleagues published details about an ongoing APT campaign targeting the Mongolian certification authority MonPass. So let us start with the Q3 report, and I must say it was a juicy quarter. Here, we would like to share with you details about emerging threats, stories behind malware strains and their spreading, and of course stats from our 435M+ endpoints telemetry. Together with my colleagues, we came to the conclusion that it would be selfish to keep our insight into this landscape just for ourselves so we decided to start with publishing periodic Avast threat reports. What was an unshakeable truth for a long time is no longer valid the next day the most prevalent threats suddenly disappear, but are usually quickly replaced by at least two new ones or that the bad guys standing behind these threats always come with new techniques when trying to get their profit. The threat landscape is a fascinating environment that is constantly changing and evolving. Latest Avast Q3’21 Threat Report reveals elevated risk for ransomware and RAT attacks, rootkits and exploit kits return.
