Threat Landscape Topic Summary Report: Cisco Talos Year in Review 2022

While our ongoing support to Ukraine and response to the Log4j vulnerabilities were two of our most comprehensive and impactful efforts in 2022, we also dealt with a multitude of other threats as the security community faced an expanding set of adversaries and malware. In January, we identified several emerging trends that we expected would affect or dominate the threat landscape in 2022, many of which ultimately played out as significant events this year. In this section, we provide an overview of the general threat landscape throughout 2022 and major trends based on telemetry sets gathered across Talos, including:

• Behavioral indicators from Secure Malware Analytics.
• Snort and ClamAV alerts .
• Behavioral Protections (BPs) from Cisco Secure Endpoint.
• Case studies from CTIR engagements.
