Exactly what the Heck are Botnets?
"A botnet is similar to mandatory military service for flowerpots" - Stromberg (http://project.honeynet.org/papers/bots/).
Botnets are networks of computer systems that hackers have contaminated and grouped together under their control to propagate viruses, send out illegal spam, and perform attacks that trigger web websites to crash.
What makes botnets extremely bad is the problem in tracing them back to their developers along with the ever-increasing usage of them in extortion schemes. How are they used in extortion plans? Picture somebody sending you messages to either pay up or see your web site crash. This situation is starting to replay itself over and over once more.
Botnets can include countless jeopardized machines. With such a huge network, botnets can use Dispersed denial-of-service (DDoS) as an approach to trigger chaos and mayhem. For instance a small botnet with just 500 bots can bring business website to there knees by utilizing the combined bandwidth of all the computer systems to overwhelm corporate systems and therefore trigger the web site to appear offline.
Jeremy Kirk, IDG News Service on January 19, 2006, quotes Kevin Hogan, senior manager for Symantec Security Response, in his article "Botnets shrinking in size, harder to trace", Hogan states "extortion plans have actually emerged backed by the muscle of botnets, and hackers are likewise renting using armadas of computer systems for unlawful purposes through ads on the internet.".
One well-known method to combat botnets is a honeypot. Honeypots help find how opponents penetrate systems. A Honeypot is basically a set of resources that one intends to be jeopardized in order to study how the hackers break the system. Unpatched Windows 2000 or XP devices make terrific honeypots offered the ease with which one can take over such systems.
A fantastic site to check out this topic more is The Honeynet Job (http://project.honeynet.org) which describes its own website's goal as "To learn the tools, techniques and motives involved in computer system and network attacks, and share the lessons learned.".
