Attacks targeting business email accounts continued to climb in the second quarter, according to data released today by specialist insurer Beazley. Hardest hit were organizations using Office 365, the popular cloud-based productivity solution.
Email accounted for 23% of incidents reported to the Beazley Breach Response (BBR) Services team during the second quarter of 2018. The attacks were broadly distributed across industry sectors.
Business email compromises are efficient for the hacker because the compromise of a single account gives the hacker a platform from which to spear phish within and outside the organization. They have soared in popularity since the beginning of last year.
