In August 2021, the MS-ISAC observed Blaknightâs return to the Top 10 Malware along with Hupigon, which made its first appearance in the Top 10. The Top 10 Malware variants comprise 73% of the total malware activity in August 2021, increasing 9% from July 2021. Shlayer and CoinMiner lead the Top 10 Malware. Shlayer and CoinMiner activity more than doubled from the previous month due to the resumption of activity in the education sector after summer vacation and are likely to continue their prevalence in the Top 10 Malware for the coming months.
