"Q4 saw malicious actors push the limits of attack vectors," said John Fokker, Head of Threat Intelligence, Trellix Advanced Research Center.

The report includes evidence of malicious activity linked to ransomware and nation-state-backed APT actors, and examines threats to email, the malicious use of legitimate security tools, and more.

PT actors linked to China, including Mustang Panda and UNC4191, were the most active in the quarter, generating a combined 71% of detected nation-state-backed activity.

Trellix observed 69% of detected malicious activity linked to nation-state backed APT actors targeting transportation and shipping, followed by energy, oil, and gas.

According to Trellix telemetry, finance and healthcare were among the top sectors targeted by ransomware actors, and telecom, government, and finance among the top sectors targeted via malicious email.

82% were sent using free email services, meaning threat actors need no special infrastructure to execute their campaigns.
