ThreatPress statistics 2017

Last year statistics were promising, a decrease of vulnerabilities is a good sign, but 2018 year started with some dangerous discoveries. In the middle of January ThreatPress found an easily exploitable vulnerability in WordPress Email Subscribers and Newsletters plugin. This plugin has more than one hundred thousand active installs and could leak a massive amount of emails and other personal data. Still, I hope this year will be safer than 2017 or 2016.
