Despite an 8% decrease in overall malware detections in Q2 2020, 70% of all attacks involved zero day malware - variants that circumvent antivirus signatures, which represents a 12% increase over the previous quarter, WatchGuard found.

Zero day malware made up more than two-thirds of the total detections in Q2, while attacks sent over encrypted HTTPS connections accounted for 34%. This means that organizations that are not able to inspect encrypted traffic will miss a massive one-third of incoming threats.

"The rise in sophisticated attacks, despite the fact that overall malware detections declined in Q2 2020, likely due to the shift to remote work, shows that attackers are turning to more evasive tactics that traditional signature-based anti-malware defences simply can't catch."

Gnaeus malware allows threat actors to hijack control of the victim's browser with obfuscated code, and forcefully redirect away from their intended web destinations to domains under the attacker's control.

Attackers increasingly use encrypted Excel files to hide malware.
