– More than half of global IT decision makers have seen a drastic increase in the number of phishing, ransomware, and impersonation attacks, as email continues to be a critical security risk to the enterprise, according to the latest State of Email Security report from Mimecast.

Notably, in just the first 100 days of 2020, impersonation fraud attempts increased by nearly one-third, which researchers believe is tied to hackers targeting the spike in remote workers amid the COVID-19 crisis.

Mimecast surveyed 1,026 global IT leaders from across all sectors between February and March 2020. The data is coupled with data gathered from screening 1 billion daily emails. According to researchers, email remains the most popular attack vector among hackers.
