Mandiant: Attackers’ Median Dwell Time Drops to 3 Weeks according to M-Trends 2022 report. Median number of days an attacker dwells in a system before detection fell from 24 days in 2020 to 21 days in 2021. State-sponsored groups “continue to be the primary actors exploiting zero-day vulnerabilities, led by Chinese groups,” report says. Report: 80 zero-days exploited in the wild in 2021, a twofold increase from previous record volume in 2019. Mandiant cites financially motivated actors as a key reason for this growth in zero day vulnerabilities.”]
