Agenda
• Network’s Exposure to Security Threats• What is Information Security And Ethical Hacking• Two Major Aspects - Desktop & Internet Security• Live Demonstrations of Attacks
“By the end of 2015, 95% of enterprises will be infected with undetected, financially motivated, targeted threats that evaded their traditional perimeter and host defenses”- By Gartner, Top Ten Key Predictions, 2012
security predictions in 2012
Network’s Exposures To Threats
Make Dangerous Virus In A MinuteWe will create this virus using batch file programming. This virus will delete the C Drive completely. The good thing about this virus is that it is not detected by antivirus.
1. Open Notepad and copy below code into it.
SAM = Security Account Manager
• The Passwords are stored in SAM fileCracking Tools :ERD CommanderPH Crack
and many more…
Cracking Login Password
That’s easy… but admin rights… hm…
OR we can Change the Password…
C:\> net user username password
You need the admin rights !
But you can change Passwords of Other Admin Users !
Today almost 87% of all viruses/worms are spread through the Internet.
Symptoms
• The system might start hanging.
• Softwares and applications often starts crashing
• System may become unpredictable.
• In some extreme cases OS may also crash.
AND
• Worms… These generally don’t perform any malicious activity.
• They reside in the system and make copies of itself
• These eat up the system resources
Trojan Horse
Trojan… is a fatal gift !
A Trojan is an infection that steals information.
It then sends the information to a specified location over the internet.
It makes the computer prone to hackers by making Backdoors.
Attacker Victim
KEYLOGGER
They log all the keys that you type.
This runs in the background and is totally invisible.
Trojans often have the keyloggers with them and they mail the log to their masters.
Watch your key strokes…!
Windows Registry
Know how change in registries effects your system……!
All initialization and configuration information used by windows are stored in the registry.
Network Scanners
Network Scanners used to find all the live systems present in the network with the Information about IP Address, Port Number, Services running on that ports, Vulnerabilities, installed applications etc.
Some Tools:-
Angry IP ScannerGFI LAN GuardLook At LAN
Finding live Hosts…!
Sniffers
Sniffers used to Capture the data packet from the network by applying some Poisoning such as ARP Poisoning.
Some Tools:-
Cain and abelEttercap
hmmmmmmmmmm…!
Cryptography
Art of Secret writing to convert plaintext(Readable format) into cipher text(Non-Readable format) by using some algorithms with the help of a Key.
Encrypters…!
Stagenography
Art of Secret writing to Hide one file behind the other file. Example a text message can be bind behind the image or video file.
Hiding……..
How Do I Protect My Data ?
•Use Antiviruses with Updated Signatures
•Use Firewalls
•Do not open Untrusted executables
•Use Cryptography Techniques
I will mess it up…!
Web Developer’s Nightmare
Website Exploits…
GoogleHacking
SQL Injection
DOS Attack
DNS Spoofing
Remote System Scanning
Google CrackingUsing Google
Google is more than just a Search Engine. Special keywords can perform better Searches.
Google crawls the web …!
<Google Commands>site, intitle, filetype, allintitle, inurl
Lets see how is this done…!
Lets see how a simple SQL injection works…
' OR '1'='1
● ● ● ● ● ● ● ● ● ● ●
Select * from table where user= ‘ " & TextBox1.Text & “ ’ AND pass= '" & TextBox2.Text & “’;
Backend SQL string
Select * from table where user= ‘ ‘ OR ‘1’=‘1 ’ AND pass= ‘ ‘ OR ‘1’=‘1 ’;
String after SQL Injection
user= ‘ ‘ OR ‘1’=‘1 ’ AND pass= ‘ ‘ OR ‘1’=‘1 ’;
We Know that… is always True…!
SQL attack…
Phishing
Fake Emails
Dangers for Internet Users…
Surfing Online…
Social Networking
Abuse
Browser Hacking
Browser Cracking• Use scripts links to run in Browser.• These scripts change the behavior of Browser.• Example: javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24;
x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i<DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin (R*x1+i*x2+x3)*x4+x5; DIS.top=Math.cos(R*y1+i*y2+y3)*y4+y5}R++}setInterval('A()',5); void(0)
javascript:b=[]; a=document.images; for(wt=0; wt<a.length; wt++){a[wt].style.position='relative'; b[b.length]=a[wt]}; j=0; setInterval('j++; for(wt=0; wt<b.length; wt++){b[wt].style.left=Math.sin((6.28/a.length)*wt+j/10)*10}; void(0)',1); void(0);
Lets Do It.........
Blast Virus<html><body><script language="javascript">while(1){w1=window.open();w1.document.write("<center><font color=red
size=5> blaaaast!!</font></center>");}</script></body></html>
Lets Do It.........
Lets Send a Fake Email !
Fake EmailsSending Fake mails with Fake headersE-mails can be sent to anyone from any Id
It is used also in Spamming
Its [email protected] ...
How to Catch Fake Emailers
Analyze the headersUse sites like
“ whatismyipaddress.com ” to trace the IP address of fake mail
Go to “Regional Internet Registries” like Apnic, Afrinic, etc.
Get the email of ISP of attacker & lodge the complaint.
Catch me if u can…
Password?
E-mail: “There’s a problem with your Gmail account”
User thinks it’s Gmail.com
(But its
Gmail.org)
Password sent
Phishing Attack
Lets make a fake page…
Preventing Phishing Read the URL carefully…
Keep a suspicious eye over info demanding E-mails.
Anti-phishing Tools can be effective…
Use your Brain…
