Doctor Web's January 2020 virus activity review

February 11, 2020

In January, Dr.Web server statistics revealed an increase in the total number of threats by 0.53% compared with the previous month. The number of unique threats dropped by 5.06%. Malicious browser extensions and adware prevailed among malware and unwanted programs. E-mail traffic was still dominated by malware that exploits vulnerabilities found in Microsoft Office programs. With that, we saw a two-fold increase in the number of banking trojan detections — Trojan.SpyBot.699.

January also showed a downward trend in encoder activity. The number of user requests to decrypt infected files decreased by 24.02% as compared with December. Trojan.Encoder.26996 was the most active encoder, accounting for 18.48% of all incidents.

Principal trends in January

  • The rise of malicious browser extensions
  • Advertising trojans and adware remain amongst the most active threats
  • An increase in the number of detected threats in e-mail traffic
  • A decline in ransomware activity
