Chapter1:Hacking–GeneralInformation

Thisbookcanhelpyoubecomeagreatcomputerhacker.Withthismaterial,youwillbe
ableto:

Think like a hacker – Since you’ll know the methods and techniques used in
hacking,youcanattacknetworksorprotectyourselffromotherpeople.

Learn about “ethical hacking” – You don’t have to use your skills to infiltrate
networksorstealdata.IntheworldofIT(i.e.informationtechnology),youmay
use your new skills to help businesses and organizations in preventing hacking
attacks;thus,youcanearnmoneybybeinga“good”hacker.

Impress your friends and family members – You may show off your hacking
abilities to other people. This way, you can establish your reputation as a skilled
programmerorcomputer-user.

Hackers –Whoarethey?
Hackersarepeoplewholovetoplaywithcomputernetworksorelectronicsystems.They
lovetodiscoverhowcomputerswork.Accordingtocomputerexperts,hackersaredivided
intotwomaintypes:
White Hat Hackers – These people are known as “good hackers.” A white hat
hacker uses his/her skills for legal purposes. Often, he/she becomes a security
expertwhoprotectscompaniesandorganizationsfromtheblackhathackers(see
below).

Black Hat Hackers – This category involves hackers who use their skills for
malicious/illegalpurposes.Thesehackersattacknetworks,vandalizewebsitesand
stealconfidentialinformation.



Important Note: These terms originated from Western movies where protagonists wore
whitehatsandvillainsworeblackhats.

Chapter2:ProgrammingSkills


To become an effective hacker, you should have sufficient skills in programming. The
ability to create and manipulate computer programs can go a long way. This ability can
help you cover your tracks or confuse security experts. However, if you want to be an
ethicalhacker,youmayuseyourskillstocreatedefensivecomputerprograms.

Well,itistruethatyoucanpurchaseready-to-useprogramsandhackingtoolsonline.That
means you may execute hacking attacks or defend your network without programming
anything. However, relying on programs created by others won ’ t help you become a
great hacker. Anybody can purchase and use a hacking program – it takes skill and
knowledgetocreateone.

Wheneveryouattack,defendortestanetwork,youshouldunderstandeverythingthatis
related to the activity. Since hacking attacks and system tests involve programs,
programming skills can help you attain effectiveness and accuracy in completing your
tasks.

Ifyouknowhowtoprogram,thenyou ’ llenjoythefollowingbenefits:

Simply put, don ’ t rely on hacking programs available in the market. Study some
programming languages and acquire the necessary skills. By doing so, you will gain

HowtoStartyourProgrammingJourney?
Itwouldbegreatifyou ’ llstudyHTMLfirst.HTML(i.e.hypertextmarkuplanguage)isa

people say that HTML is simple and easy to master. That means you can learn this

Chapter3:Passwords


These days, passwords serve as the exclusive form of protection for networks and
websites. If you have this piece of information, you will gain complete access to the
owner ’ saccount.Thisisthereasonwhyhackersusedifferenttoolsandtechniquesjustto
getpasswords.

PasswordCracking –TraditionalApproaches
Thefollowinglistshowsyouthetraditionaltechniquesusedincrackingpasswords:
Guessing–Thisapproachisonlyeffectiveforweakpasswords.Forexample,ifthe

ImportantNote:Thissectionusessomecomputerprogramsthatyouneedtoinstall.

TheDictionaryAttack
Inthisapproach,youhavetouseatextfilethatcontainscommonpasswords.Youwilltry
each password to see which one works. This approach offers ease and simplicity.
However,youcanonlyuseitforweakpasswords.Tohelpyouunderstandthistechnique,
let ’ sanalyzethefollowingexample:

A hacker uses Brutus (i.e. a popular password-cracking program) to access an FTP (i.e.
filetransferprotocol)server.

Beforediscussingtheexample,let ’ stalkaboutFTPserversfirst.AnFTPserverallows
youtosendorreceivefilesthroughtheinternet.Ifahackergainsaccesstoasite ’ sFTP
server,hemaymanipulateorremovethefileswithinthatserver.

Now,you ’ rereadyfortheexample.Herewego:

2. Then,helaunchesBrutustocracktheserver’spassword.



3. Heindicatestheserver’stype(i.e.FTP)andIPaddress.

4. Heentersavalidusername.

5. Hechoosesthetextfilethatcontainsthepasswordlist.

6. HeclicksontheStartbutton.TheBrutusprogramwillconnecttotheFTPserver
and try to log in using the passwords inside the text file. If the process is
successful,Brutuswillshowthecorrectpasswordinits“PositiveAuthentication
Results”section.Here’sascreenshot:


Important Note: Elite hackers use a proxy whenever they use this kind of computer
program. Basically, a proxy hides your IP address by transmitting connection requests
fromadifferentcomputer.Thisisimportantsincemultipleloginattemptscreatealotof
electronic “ footprints. ”

TheBrute-ForceApproach
ITexpertsclaimthatthisapproachcancrackanytypeofpassword.Here,thehackertries


all possible combinations of numbers, letters and special symbols until he gets into the
targetedaccount.Themaindrawbackofthisapproachisthatitistime-consuming.Thisis
understandable – you have to try thousands of possible passwords just to access the
target ’ saccount.

Thespeedofthisapproachdependsontwofactors:

Brutus,thehackingtoolusedinthepreviousexample,canalsolaunchbrute-forceattacks
againstaserver.Here ’ showitworks:

1. Specifythetarget’sIPaddressandservertype.Inthe“PassMode”section,select
“BruteForce”andhit“Range.”Theimagebelowwillserveasyourguide:

2. The screen will show you a dialog box (see below). Use this dialog box to
configurethebrute-forceapproach.Obviously,yourjobwillbewaymuchsimpler
ifyouhavesomeideaaboutthetarget’spassword.Forinstance,ifyouknowthat
the website requires passwords with 5-10 characters, you’ll be able to narrow
downthepossibilitiesandshortenthewholeprocess.




3. HittheOKbutton.Brutuswilllogintothetargetedserverbytryingallpossible
passwords. You’ll see the results on the program’s GUI (i.e. graphical user
interface).


Phishing
In this technique, you ’ ll steal confidential information (e.g. passwords) by fooling the
victim.Forexample,ahackerpretendedtobeabankrepresentativeandsentanemailto
thetargetuser.Theemailrequiredtheusertochangeherpasswordbyclickingonalink.
Whentheuserclickedonthelink,shesawawebsitesimilartothatoftheactualbank.The
website,however,isjustareplica.Anyinformationenteredtherewillgotothehacker ’ s
databaseoremailaccount.

Important Note: Elite hackers use HTML to create phishing sites that look like official
ones.

Herearethethingsyouneedtodowhencreatingaphishingwebsite:
1. Chooseyourtarget–Mosthackersmimicthewebsitesofemailserviceproviders.
Therearetworeasonsforthis:

1. Userslogintotheiremailaccountregularly.Thatmeansthehackerhasa
lotofopportunitiestofoolhistarget.



2. Emailaccountsareextremelyuseful.Mostofthetime,anemailaccountis
linked to other accounts (e.g. bank accounts). Thus, you can get loads of
informationabouttheuserjustbyhackinghisemailaccount.

Forthisbook,let’sassumethatyouwanttocreateaphishingsiteforGmail.

2. Copy the official webpage – Launch Mozilla Firefox (hackers recommend this
browser because it is secure and customizable) and access the login page of the
actual website. Press CTRL+S on your keyboard to create a local copy of the
webpage.


3. Renamethefile–Aftersavingthewebpage,changeitsnameto“index.htm.”The
index page is the first webpage that shows up whenever someone reaches a
website; thus, you want the target user to believe that he reached the index
webpageoftherealsite.

4. Create a script – You should create a computer script that will record the user’s
login information. Most hackers use the PHP scripting language to accomplish
this task. The image below shows you a basic PHP script that records login
credentials.

LaunchNotepadandenterthescript.Savethefileas“phish.php”.
