67% of all malware in Q1 2020 was delivered via encrypted HTTPS connections and 72% of encrypted malware was classified as zero day, so would have evaded signature-based antivirus protection, according to WatchGuard.

"Some organizations are reluctant to set up HTTPS inspection due to the extra work involved, but our threat data clearly shows that a majority of malware is delivered through encrypted connections and that letting traffic go uninspected is simply no longer an option," said Corey Nachreiner, CTO at WatchGuard.

"As malware continues to become more advanced and evasive, the only reliable approach to defense is implementing a set of layered security services, including advanced threat detection methods and HTTPS inspection."

Five of the top ten domains distributing malware in Q1 either hosted or controlled Monero cryptominers.

The Cryxos trojan was third on a top-five encrypted malware list and also third on its top-five most widespread malware detections list, primarily targeting Hong Kong.
