Hackers and the web

So we all know that hackers try to do many things while using a PC. Many of those things though can be harmless at time can also pose as very dangerous. It's no big surprise these days to hear of hackers doing this or that but to what extent will they reach? In an article I read recently which is provided on this(link) and hosted on "InfoWorld" shows the story of some hackers injecting well known and supposedly trusted websites with malicious code that redirect users to web pages where they try to install fake spy ware programs or inject trojan horse programs into the users PC. By using the Google database and these websites, the hackers use the search queries so that unsuspecting users will find these links and in hopes to click and access the material behind that hyper link. Thus falling for the trap that was set. To what extent could these people be thinking? I can't seem to understand what goes through the mind of someone who simply wants to give others a hard time and inconvenience them. A lot must go through the mind of the individual that decides they want to use the internet in a way to benefit their own gains or to pet their ego. Listed in the article it was noted of some major websites that were hit with this type of hacking. Among those was walmart.com, usatoday.com and target.com but it is estimated that many more websites have already fallen prey to this type of hacking. The only advice they can give to website operators is to search their query functions regularly and eliminate the presence of this malicious html code in the search results.
