Unit 42 researchers observed network attack trends, February-April 2021. In the following sections, we present our analysis of the most recently published vulnerabilities, including the severity and category. Additionally, we provide insight into how the vulnerabilities are actively exploited in the wild based on real-world data collected from Palo Alto Networks Next-Generation Firewalls. We then draw conclusions about the most commonly exploited vulnerabilities the attackers are using, as well as the severity, category and origin of each attack.
