There was an attack on Hostmonster Wordpress installations three days ago, and hostmonster added a lot of IP addresses to a blacklist.

I think they used the kitchen sink method to determine who was attacking, because too many folks are having this problem.

http://SanPedroDaily.com, http://BelizeNews.com, http://BelizeSearch.com, http://sagahumanesociety.org are among sites hosted by hostmonster, and might be giving you a problem. Of those sites, only the SAGA site is a WordPress installation, so you don't have to be running a wordpress site to have your site be affected if your website is hosted by hostmonster.

If you are unable to get onto certain sites because it says your IP is blacklisted, here is why

================

Hello,

Thank you for contacting our support department. I apologize for the recent issues you are having.

It looks like your IP address has been added to our local blacklist because it was part of an attack on our servers targeting WordPress sites three days ago. This means that your computer was hacked and used by the hackers as part of this attack. Please use an antivirus program to scan your computer for the virus which caused this problem.

If you have no antivirus program, I would suggest Avast! Antivirus, which is available for free on Mac and Windows:

When you have removed the virus, please contact us back so that we can remove your IP from the blacklist.

============

So if you have that problem, run an antivirus check on your system, then contact hostmonster at 866-573-4678 option 2 for tech support and tell them you checked your system and it has no viruses and please take you off the blacklist.

here's what shows oncreen if you have been blacklisted

Access denied. Your IP address [xx.xx.xx.xx] is blacklisted. If you feel this is in error please contact your hosting providers abuse department.

you get this after you have been removed from the blacklist

======================

The IP addresses have been added to our whitelist.

There are also a few things we recommend you do to prevent your account from being compromised: (if you have a WordPress installation)

Change your username to something unique. Change your password, make it strong. (The bots are targeting their attack to users who kept admin as their default username. )
Install an login-limiting plug-in: http://wordpress.org/extend/plugins/wordfence/
Turn on two-step authentication: http://en.blog.wordpress.com/2013/04/05/two-step-authentication/
Update your WordPress (in fact, update all of your plug-ins)
