Last year was a busy one in the world of website security. Our 2019 Threat Research Report shows that over 60% of websites we cleaned had a vulnerability at the point of infection, up 4% over 2018. SEO spam remained a universal threat, while backdoors allowed hackers to reinfect sites recovering from an initial attack.
Much is due to outdated CMS software and applications (like plugins and extensions) — an attack vector which, along with other vulnerabilities, facilitates the hacks and attacks we’re about to cover.
