Emails containing malicious URLs made up 88 p.c of all messages with malware-infested hyperlinks and attachments, underscoring the dominance of URL-based e-mail threats.

“From large malware campaigns concentrating on thousands and thousands of recipients with banking Trojans to rigorously crafted e-mail fraud, the e-mail menace panorama is extraordinarily numerous, creating a variety of alternatives for menace actors to assault organizations,” Dawson added.
