As I write this put up, there’s an on going and extremely distributed, world assault on wordpress installations to crack open admin accounts and inject numerous malicious scripts.
To offer you a bit historical past, we lately heard from a significant regulation enforcement company a few huge assault on US monetary establishments originating from our servers.
We did an in depth evaluation of the assault sample and discovered that many of the assault was originating from CMSs (largely wordpress). Additional evaluation revealed that the admin accounts had been compromised (in a single kind or the opposite) and malicious scripts have been uploaded into the directories.
In the present day, this assault is going on at a world degree and wordpress situations throughout internet hosting suppliers are being focused. Because the assault is extremely distributed in nature (many of the IP’s used are spoofed), it’s making it troublesome for us to dam all malicious information.
