During the month, the share of the phishing emails in total email traffic increased two times compared to February and averaged 0.006%, the analysts said.
"The two fold increase in the amount of phishing emails in March means users must be more watchful with their email," Shcherbakova added.
In March, the phishers’ attacks were mostly targeted towards Social networking sites, Financial and e-pay organisations, and Search engines, in first three positions respectively.
