Spy Gadgets

When many computers have been hacked to turn them into zombies computers, we call such a group a Botnet. Those computers are being used by cyber criminals to send spam emails and/or to attack websites. These botnets are created by ‘bots’, malicious programs that turn individual computers into ‘zombies’ which can be remotely controlled by the attacker via a ‘bot-herder’ command and control server. Botnets are one of the more dangerous types of menace which occur in cyberspace, as they can harm whole networks as well as individual computers. Problems like viruses, malware, spyware can also be distributed via those Botnets, besides all the spam emails. Denial of Service (DoS) and Distributed Denial of Service (DDos) are 2 others popular methods to hurt servers that hackers are doing with those Botnets.

Such instructions might include to start sending lots of spam emails, or to attack a remote website or server, or simply to propagate the Botnet to others PCs.
