A new worm had attacked the major social netwoking service Orkut. In the second major XSS (cross-site scripting) attack on this social networking site this week, Orkut was flooded with "Bom Sabado!" scraps.

The word "Bom Sabado" means "Good Saturday" in Portuguese, which is the also the official language of Brazil, one of the last remaining Orkut bastions in the world.

Some times we have to hide apache banner information, because hackers may check version details, before attacking a sever. If you hide this, it is more difficult for them to exploit any system holes and thus making vulnerability scanners work harder and in some cases impossible without knowing version information.
