A friend of mine who I help with a wordpress site was hacked. They didn’t take his site down, rather they placed a ton of spam links hidden in his code.
That made me decide to check all my sites and sure enough this site had literally THOUSANDS of spam links hidden in the footer. Everything from erectile dysfunction to medical pot.
So I’ve changed my password, removed the malicious code and I’ll be upgrading to the newest version of WP in hopes that whatever security hole they exploited will be plugged.
