Introduction To Botnets
[What]a group of computers or servers all compromised with the same backdoor. The interesting thing about botnets is that these backdoors often have the ability to interact with other members of the botnet, and can also be controlled by the botnets owner. This can result in a single command, e.g. DDoS Microsoft.com, to flow down a chain of command in an instant, telling each member of the botnet to follow it. They also often leave backdoors accessible to the botnet user, and some even have built-in protocols for updating themselves. There are multiple chains of command that have been used in botnets, and these are:
P2P botnets, using these a command can be sent by the hacker to a single member of the botnet, and this single botnet will pass the command on to a handful of other members, which will carry on the chain and so on and so forth. the advantages of this are you cannot stop the botnet by taking out one member, but you would have to block the botnet completely. The problem is it is easy for individual bots to become separated from the rest of the net, usually resulting in being fixed.
Heirarchial botnets, which have different members assigned "ranks” in the command chain and are given specific bots to manage. Using this, the hacker might send a command to 4 different bots, which each pass the message on to 100, which each pass it on to 100. The problem with these is that the botnet can be shut down by removing the hack from one of the higher-up bots. The good thing about these is they can be very easily automated, and can pass reports of the computers up the chain as well as pass exploit upgrades down.
and single server bots, which all take their commands from one computer, these are very easy to make but are near enough useless.
[Propagation]
Botnets can be propagated by the hacker themselves, eg whenever they root a server or trojan a computer they add their program in too, run it and that computer becomes a bot. Another way is by mimicing worms and spreading through emails, p2p or instant messaging. Be imaginative, there are many ways of propagating that havent been tried yet.
[usage]
I will give an example of how a p2p botnet would be structured.
The bots propagation method is by exploiting a flaw in the security system of linux, and uses it to get root access.
The bot has a p2p structure, and can pass patches down the chain as well as commands.
The bot is automated by adding any computers it hacks to its own list of child bots(ones under its own command), and runs a check similar to ping to test if the net is up on the child before sending commands/patches.
[Famous Examples]
the storm worm:
This is an email-spread worm that takes over windows machines and injects a driver into the windows kernel to keep root. It currently has control of between 1- and 10- million windows machines around the world. It is extremely flexible, and has avoided gaining a signature for a massive amount of time.
There are many of examples on wikipedia of these, and google yields some interesting results.

Google Search Tricks 2010
A few things you might want to try with Google:
Hand type the following prefixes and note their utility:
link:url Shows other pages with links to that url.
related:url same as "what's related" on serps.
site:domain restricts search results to the given domain.
allinurl: shows only pages with all terms in the url.
inurl: like allinurl, but only for the next query word.
allintitle: shows only results with terms in title.
intitle: similar to allintitle, but only for the next word. "intitle:webmasterworld google" finds only pages with webmasterworld in the title, and google anywhere on the page.
cache:url will show the Google version of the passed url.
info:url will show a page containing links to related searches, backlinks, and pages containing the url. This is the same as typing the url into the search box.
spell: will spell check your query and search for it.
stocks: will lookup the search query in a stock index.
filetype: will restrict searches to that filetype. "-filetype:doc" to remove Microsoft word files.
daterange: is supported in Julian date format only. 2452384 is an example of a Julian date.
maps: If you enter a street address, a link to Yahoo Maps and to MapBlast will be presented.
phone: enter anything that looks like a phone number to have a name and address displayed. Same is true for something that looks like an address (include a name and zip code)
site:www.somesite.net "+www.somesite.+net"
(tells you how many pages of your site are indexed by google)
allintext: searches only within text of pages, but not in the links or page title
allinlinks: searches only within links, not text or title
I hope there is something new in here for you and maybe this infos will be helpfull for ya.
If you want to search for something and you know that it would be in the title then you can use this field. Just enter in the title: ”your search item” into Google and hit enter. It will return the search results with the search word on the title of the page. Suppose you want to search for rules for Google search and you vaguely remember some article you once read called golden rules of google searching. You can give your search query as:
intitle:Golden Rules of Google searching If you put your search words in quotes then Google will treat it as a single word and you will get much better search results:
intitle:”Golden Rules of Google searching”
inurl Searches can be done for urls using this following operator. If you want to find the search string in the URL of the website, then you enter something like:
inurl:golden.rules.of.google Please note here that I have put ".” in between the words. ".” This period acts as a wild card and can replace any other symbol such as a hyphen or an underscore. This search will in turn bring all the pages which have both: golden-rules-of-google and golden_rules_of_google.
filetype This is my favorite operator. Using this, you can search for a specific file type in the internet. Suppose you want to search for a document for linux and you only desire PDF file types. The query you should enter into Google is as follows:
filetype:pdf linux If you want to search for mp3 music to download, type filetype:mp3 and the artist name followed by that. This search will fetch you any such mp3 file in the pages which Google has crawled.
link The Link operator is another very useful tool. It is used to find the webpages which have a link to a specific URL. Suppose I have a blog and I want to find out how many pages link to this page. All I need to do in this case is use the link operator. Please note that unlike other operators, we are not going to give a search word for this operator. Instead we are going to give a full URL, something which looks like this:
link:http://iamjaison.blogspot.com This will give you an indication as to the popularity of the page.
inanchor The inanchor operator is similar to the URL operator, but it is used to help you find the text which is included inside an anchor or a link. For example, if you want to find out all anchors which have the know-how to do speed squaring using vedic mathematics, then you should type:
inanchor:"Speed Squaring using Vedic mathematics" This will locate all the anchors that have got a link built up under that phrase.
daterange Daterange will search for pages which were published between the specified two dates. This comes handy when we have to find out pages which are more recent, but it is more difficult than you might think. The catch here is that we have to pass the dates in Julian format. The julian date is the number of days passed after January 1st 4713 BC. For example, the date September 11, 2001, is represented in Julian terms as 2452164. So, to search for pages that were indexed by Google on September 11, 2001, and contained the word "crash” the query would be:
daterange:2452164 - 2452164 "crash” This will report all those pages Google crawled in that time frame which had the word crash in it.
related This is a superb operator which is quite fun to use. Suppose you discovered a very useful website, for example: Dictionary and you are wondering what other sites might be used as an alternative for this one. In short, you need to find out all those sites which are similar to dictionary.com. You can do just that using the related operator. I am going to show you the sites which are related to Google . For that, I am going to write the below query in google:
related:www.google.com Just have a look which one comes first in the list.
phonebook There are many operators which I discussed earlier which can be used for evil purposes. I did not cover those operations as I did not want anyone to get into any trouble. This is one such thing. I am covering this because there is a workaround for the problem. The phone book operator can be used to find both the official and residential phone numbers of people. Three operators can be used for the phonebook search: rphonebook, bphonebook and phonebook, which will search residential listings, business listings, or both, respectively. A query such as:
phonebook:abc def ny would list both business and residential listings for abc def in New York. If you're concerned about your address information being in Google's databases for the world to see, have no fear. Google makes it possible for you to delete your information so others can't access it via Google. Fill out the form at www.google.com/help/pbremoval.html and your information will be removed, usually within 48 hours.
insubject This nifty little operator will allow you to search google groups by the subject line. Suppose you are facing some problem with the Windows XP startup and you want to see the threads in Google groups which have discussed it. All you need to do is type in:
insubject:”windows xp startup” and Bingo, all that information will be presented in front of you. Please make sure that you are inside the google groups search page before attempting this query, otherwise it might not work correctly.
define This operator can be used if you don't have any dictionary at your disposal and you want to quickly decipher some professional jargon or find the meaning of a rather difficult word that you have never heard before. How about the word abracadabra? Have no fear, just go to Google and type in:
define:abracadabra And there you are, Google comes up with all the definitions it can find, selected just for you
Hand type the following prefixes and note their utility:
link:url Shows other pages with links to that url.
related:url same as "what's related" on serps.
site:domain restricts search results to the given domain.
allinurl: shows only pages with all terms in the url.
inurl: like allinurl, but only for the next query word.
allintitle: shows only results with terms in title.
intitle: similar to allintitle, but only for the next word. "intitle:webmasterworld google" finds only pages with webmasterworld in the title, and google anywhere on the page.
cache:url will show the Google version of the passed url.
