Millions of sites were attacked this week, said Defiant, the company behind the Wordfence firewall.

The sudden rise of happened when hackers discovered and began exploiting a 0day vulnerability in “File Manager, A WordPress plugin used on more than 700.000 websites.

0day allowed an attacker to upload malicious files to a site running an older version of File Manager.

It is not known how they discovered 0day, but all last week the hackers started looking for sites that had this add-on installed.

If the was successful, attackers were exploiting 0day and uploading a web shell disguised as a file s on the victim's server. So they could access the site, adding it to a botnet.

The attacks started late, but intensified throughout the past week. Defiant detected attacks on 1 million WordPress sites as of Friday, September 4th.

In all, Defiant has blocked attacks on more than 1,7 million websites since September 1, when the attacks were first discovered.

The good news is that the File Manager developer team created and released an update for 0day the same day they learned about the attacks. Some administrators installed the update immediately, but as usual, there are others who did not.
