SSL-Based Phishing Surges 400% from 2017

Hackers are increasingly using encrypted traffic to hide their attacks from security filters, with phishing emails soaring in popularity, according to new data from Zscaler. The cloud security provider processes more than 60 billion transactions per day and claimed that hiding threats in SSL traffic has become standard practice among the black hats. Its biannual 2019 Cloud Security Insights Threat Report revealed that the vendor blocked 1.7 billion advanced threats hidden in SSL traffic from July to December 2018, amounting to an average of 283 million per month. This included 2.7 million phishing attempts each month, an increase of over 400% from 2017 figures. This chimes somewhat with a new report from Trend Micro released this week, which revealed the vendor blocked 269 million phishing URLs last year, a 269% increase over 2017.
