Yusufali-A - trojan against 'black web'

Experts at SophosLabs lab - a virus and spam analysis research center of Sophos security company - have just announced a new type of trojan capable of preventing access to 'black web' pages by How to display the Koran passages.

Trojan Yusufali-A once infected on a user's computer will track the user's Internet access by checking the subject line on the active window. If the trojan discovers 'banned' words such as "teen", "xx", "sex" or "penis" . it will immediately shrink the browser window so that the user cannot view it. content of those sites.

At the same time show a passage of the Koran that says' Know, therefore, that there is no God, and ask forgiveness for thy fault, and for men and women who believe: for Allah knows how to move and how ye dwell in your homes. ' (So ​​I understand that there is no God but Allah and I ask you to forgive me for the faults of the men and women who believe in Allah because Saint Allad knows where are you going and where are you living? '

If the user continues to access or not close the window containing the 'black web' page, the trojan continues to display excerpts in the Koran and finally displays a button titled 'For Exit Click Here '. But as soon as the cursor moves, the trojan will display a rectangular box with the text 'OH! NO i'm in the Cage '. In that box, there are three Log Off, Shut Down and Restart buttons, the cursor will be locked in this box and all actions will result in the computer being turned off.

Graham Cluley, Sophos senior technology consultant, said Yusufali-A is not the same as any other dangerous software. This trojan does not aim to financially benefit or steal important personal information, but acts as a protector of moral values ​​by preventing access to the websites it supposed to be 'black web'. But of course, this trojan also has some errors that often prevent websites that have no bad content like medical websites or adolescent social sites.
