Facebook virus flooding into various social networks

Bkjia.com exclusive Article] "Koobface" is a trojan horse worm. Due to the recent spread among Facebook users on social networks, it is also known as the Facebook virus. However, the name of "Facebook virus" will soon become a thing of the past, because the virus has jumped out of the Facebook wall and rushed to other social networks, such as Bebo, MySpace, Friendster, MyYearbook, and Blackplanet.

1. Introduction to Koobface

Once the computer is infected with the Kooface worm, it will leave a message to the host's friends page. These messages seem to come from infected users. They have the following content: "Is this your first performance ?" "Where are you ?" "It's so memorable. I can assure you that this video is definitely yours ." "Where did you get your miniature camera ?" "I didn't expect you to be the main character !" "I really envy you !" "Who is the last person? I don't know him ". The people who receive these messages are curious: do these guys actually see me in the video? Therefore, you cannot help clicking the link in the message.

In fact, these links will take them to a page outside the station and provide videos from "YuoTube" on fake clothes, however, after a while, you need to install a new version of Adobe Flash Player to continue watching. Then, if you click the Install button, you will be moved to the trap. When users are infected, they are directed to other contaminated sites when using the search engine, which leads to many security problems, such as identity theft. Because the words searched are redirected to search for items, click fraud and AD hijacking are performed.

2. Social Networks will become a new breeding ground for viruses

Although Koobface may not be the first malware to attack social networks, it has been widely used.

It has caused great user panic. What people are worried about is not that the worm can spread itself-which is common to malware-but its transmission method. In recent years, people have been vigilant against unknown links and additional links in their emails, but virus writers have found their new "lifeblood"-social networks. Here, many people are not only alert-free, but also feel safe. But these people are wrong. The Ancients cloud, the heart of the harm cannot be, but the heart of the defense can never be lost-this is an everlasting truth!

In fact, this trojan is widely spread mainly because people usually do not care about the links or messages provided by their acquaintances. Although people have doubts about emails with unknown origins, they trust messages from Facebook. In view of this, it is estimated that more and more attacks will be targeted at social networks in the future, and the attack forms will become increasingly advanced. This situation will not improve until people are generally vigilant about social networks.
