U.S. named top origin of email threats: Over 50 million emails containing malware attachments were identified as originating in the United States in 2021, according to the report. In second place was China, with over 10 million threats identified, followed by the Netherlands, with just under 10 million email threats originating from the country.
.XLS files were the most common virus file type: When it came to the type of file containing malware, .XLS files were seen the most often by the report, followed by .HTM and .ZIP files.
