Horror of Zombies

Share

What is a Zombie ? Zombie by definition is computer that has been implanted with a daemon (Pronounced DEE-mun or DAY-mun) that puts it under the control of a malicious hacker without the knowledge of the computer owner. That is your computer has been taken over by a hacker which you may not be aware of. Computers that have become Zombies are used by the malicious hackers who had obtained its control to launch DoS attacks (denial-of-service attacks). On hacker’s command, the zombie computer sends an enormous amount of packets of useless information to a targeted Web site in order to clog the site's routers and keep legitimate users from gaining access to the site. The traffic sent to the Web site is confusing and therefore the computer receiving the data spends time and resources trying to understand the influx of data that has been transmitted by the zombies. Compared to programs such as viruses or worms that can eradicate or steal information, zombies are relatively benign as they temporarily cripple Web sites by flooding them with information and do not compromise the site's data. Prominent sites such as Yahoo!, Amazon and CNN.com were brought down in 2000 by zombie DoS attacks. Want to know more about such computer terminology in details. Read on this link Zombie Computers

So the internet has tackled the horror of Zombies successfully. But we may actually see a real Zombie in future. Scientists at the Safar Centre for Resuscitation Research, Pittsburgh, USA has successfully created eerie zombie dogs, reanimating the canines after several hours of clinical death in attempts to develop suspended animation for humans. subject's veins are drained of blood and filled with an ice-cold salt solution. The animals are considered scientifically dead, as they stop breathing and have no heartbeat or brain activity. But three hours later, their blood is replaced and the zombie dogs are brought back to life with an electric shock. Plans to test the technique on humans should be realised within a year, according to the Safar Centre. Don’t believe. Read on this news link Zombie Dogs Recreated
