Hacker Attacks That Can Damage Your Site & SEO

Hacker Attacks That Can Damage Your Site & SEO

A great thread over at WebmasterWorld forums lists most common hacker attacks types, their footprints and features.

These attacks can cause damage to the presentation of your site, the users who visit your site, and also leave a negative taste on your search engine rankings.

I’ve figured the discussion is worth attention and organized it into a short table also adding:

  • some tools that can help to detect the attack;
  • links to related articles and discussions.
