WordPress sites are experiencing a large increase in hacks that deliver malware and ransomware to first-time, unsuspecting users. It is not yet clear how this is happening but it is being looked into extensively. No one should be visiting WordPress sites with out-of-date versions of Adobe Flash Player, Adobe Reader, Microsoft Silverlight, or Internet Explorer. With these outdated systems, you can find your computers infected with the ransomware package, which puts a hold on your computer system until you pay a hefty ransom.
To disguise the attack furthermore, the code redirects users through a series of sites before delivering the malware. It is possible that hackers are regularly updating malware when old ones get flagged.
This shows that trustworthy sites can still expose you to malware and hacks. The best way to prevent hacks is to be up-to-date on security updates when they become available.
