De BISAWiki
How do you realize in case your crack site has been hacked? Sometimes you will know due to the fact the website has dropped precipitously within the search engine rankings for no apparent reason. Or a lot of of the pages are no longer being indexed by the search engines. Or guests send you emails complaining that their anti-virus computer software warns them away from your website. These are not great items to possess occur, mainly because by then the damage has been accomplished.
A superior approach to to proactively scan your web-site for hacked pages. What you might be looking for are unauthorized hyperlinks to external web-sites, for the reason that most hackers use those hyperlinks to increase the search engine rankings of their own websites. That makes most hacked pages easy to seek out using a few uncomplicated search engine queries.
The crucial should be to combine the "site:" command with a single or extra frequently utilised hacker ranking terms like "viagra" or "cialis". The "site:" command restricts search engine benefits to pages from the offered domain. One example is, the query:
web-site:about.com
restricts the search towards the "about.com" domain. All you need to do is add one particular or two hacker-targeted keywords and phrases to the query, as in:
web site:whitehouse.gov viagra
That query will return all indexed pages on the "whitehouse.gov" domain that include the word "viagra". (As I create this, you will discover in fact two pages on the official White Property website that have been hacked within this manner. Oops!)
While "viagra" is the most obvious term to look for, you will find other possibilities. Any erectile dysfunction drug is really a candidate: "levitra", "cialis", etc. Generic version in the brand names are also well known: "sildenafil", "vardenafil", etc. Truly, any kind of high-demand pharmaceutical solution is actually a very good candidate, though you can also appear for money-making schemes (assume "forex" or "online gambling") as well as other issues that a spam catcher would commonly isolate within your incoming e mail.
Needless to say, you may not really see these hyperlinks around the pages in query. Hackers do their finest to hide the hyperlinks from human guests. However they usually do not hide them from search engines like google, due to the fact the point would be to get the search engines like google to locate these links and count them as "votes" to finding their own "money sites" to rank highly for sought-after, extremely commercial and really competitive terms. That's why a very simple search query exposes hacked pages.
What do you do once you have discovered a hacked page on a single of the websites? It depends upon how the links were added for your pages and how your pages are generated. You will discover a great deal of support on-line on the way to do away with hyperlink spam from a website and the way to "harden" your web site against future attacks.
