[news release] The latest Kaspersky Lab Spam and Phishing Report has discovered that although the quantity of spam emails has been decreasing, they have become more criminalized. At the same time, the level of malicious mailshots has dramatically increased - Kaspersky Lab products prevented 22,890,956 attempts to infect users via emails with malicious attachments in March 2016, twice the number of attempts reported in February 2016.
Since 2012 the level of spam in email traffic has constantly been decreasing. However, the quantity of emails with malicious attachments has increased significantly - in Q1 2016 it was 3.3 times higher than during the same period in 2015. There was also a growing amount of ransomware reported throughout the quarter. This is often propagated through emails with infected attachments - for example Word documents. The main actor on this field in Q1 was the ransomware Trojan Locky, which has been actively distributed via emails in different languages and has targeted at least 114 countries. Locky emails have contained fake information from financial institutions that have deceived users and forced them to open the harmful attachment.
Kaspersky Lab's findings suggest that spam is becoming more popular for fraudsters to target Internet users, because web browsing is becoming safer. Almost all popular web-browser developers have now implemented security and anti-phishing protection tools, making it harder for cybercriminals to propagate their malware through infected web pages.
