U.S. entities remained the most attractive targets of phishing attacks throughout 2018, with an estimated 84% of the total volume of millions of incidents analyzed during the last year by threat intelligence company PhishLabs.

While in 2017 U.S. organizations were hit by 85% of all phishing attacks launched worldwide and detected by PhishLabs, the 1% decrease in share did not translate into a decrease in overall volume.
