i just got a mail from my site security plugin about a hack attempt on my site. what to do in this situation. can i feel relaxed or i need to do something more the message was This notice is to inform you that someone at IP address 31.184.242.194 tried to login to your site "Indiaonindia" and failed. The targeted username was admin The IP address has been blocked for 60minutes.
Make sure your version of Wordpress is completely up to date...the hack will be targeting a number of files including your index.php file and contain a block of code that looks like a load of numbers and letters usually towards the top of the page.
It sounds like you are using Login-Lock plugin for wordpress. If so, go into WP and set the plugin to block anyone after 3 attempts for 999999999999 minutes. If you check your WP database and you'll see 2 tables for this plugin. They include all of the IP addresses that have attempted an improper login. There is a bug though with Login-Lock I have noticed lately. When you login after a WP update it wont let you login and gives you a loop error. Dont know if there is a fix or not - checked yesterday (5/14) and there was not.
Re Install wordpress and delete wp-login.php file when you are not going to login you can also use limit login attempts plugin it's good
if you know which ip address is trying to hack you, you should be able to block them using .htaccess (just back it up before making any changes)
