Cyber attacks are growing vigorously in the internet world. Recently hackers attacked a popular social networking site, Twitter ,where users can post 140 character messages to their friends, resulting in the shutdown of Twitter for two hours on Thursday (06/08/2009) morning and caused glitches in world’s popular social networking site Facebook.

Twitter and Face book users were not able to access the networking sites for several hours on the day. Even after the Twitter site come back online, many site users continuously encountered some problems. The site users were worried that the sites were not working properly.

“We are trying to defend ourselves and recover from this attack,” the message from the company says. After a lot of discussions, Facebook, Twitter and Google worked together to resolve issues in a fairly short period of time. Users are now posting their messages to their followers without any difficulty.

“It is very difficult to identify hackers and when they will attack as they could be anywhere in the world” said John Harrison, a researcher with the Web security firm Symantec. So it is better to update an anti-virus software on your computer frequently, and create password that is difficult to crack and stay away from the cyber attack problems, the U.S. Computer Emergency Readiness agency advices.
