According to the latest data from security firm PhishMe, 93% of all phishing emails as of the end of March contained encryption ransomware. The numbers underscore a growing trend in the security space as ransomware instances in phishing emails grew up by 56% since December last year. From a report: The anti-phishing vendor also counted the number of different variants of phishing emails that it saw. Ransomware accounted for 51 percent of all variants in March, up from just 29 percent in February and 15 percent in January. The skyrocketing growth is due to that fact that ransomware is getting easier and easier to send and that it offers a quick and easy return on investment. Other types of cyberattacks typically take more work to monetize. Stolen credit card numbers have to be sold and used before the cards are canceled, for example. Identity theft takes even more of a time commitment.
