Center for Internet Security: Top 10 malware in September 2020
According to the Center for Internet Security (CIS), in September 2020, three malware returned to the Top 10: CoinMiner, CryptoWall, and Emotet. The Top 10 Malware variants composed 87% of Total Malware activity in September 2020, up from 78% in August 2020.
The increase, says CIS, is largely due to the recent Shlayer campaign ramping up, as the education year begins for universities and K-12 schools. "Due to the new education year, Shlayer is highly-likely to continue its prevalence in the Top 10 Malware for the coming months. Additionally, this month the MS-SIAC saw an increased number of Emotet alerts, as it reemerged from dormancy to continue malspam campaigns resulting in secondary Qakbot and TrickBot infections," CIS noted.
