“It’s still not clear how, but a disproportionately large number of websites that run on the WordPress content management system are being hacked to deliver crypto ransomware and other malicious software to unwitting end users.
In the past four days, researchers from three separate security firms have reported that a large number of legitimate WordPress sites have been hacked to silently redirect visitors to a series of malicious sites. The attack sites host code from the Nuclear exploit kit that’s available for sale in black markets across the Internet. People who visit the WordPress sites using out-of-date versions of Adobe Flash Player, Adobe Reader, Microsoft Silverlight, or Internet Explorer can then find their computers infected with the Teslacrypt ransomware package, which encrypts user files and demands a hefty ransom for the decryption key needed to restore them.”
Keep an eye on your sites folks. It’s not clear how this is happening, but it might not hurt to check on the .js files in your WordPress install.
