2. Disclaimer :
I am here not to teach you
Hacking but I want you to
be on High Alert against
“Cyber Terrorism”

3. We believe that they are Dangerous !!!
Ku Klux Klan
26/11 Attack Head
ISIS Head

4. I Personally feel…. NO, not that much !!
They are thousands of miles away from
India...

5. Yes… Using Side effects of
Cashless India, they just need to Hack
only 1000 bank ACCOUNTS and let this
news spread via Indian Media and will create
Chaos...

6. and Yes...from 1000’s of miles away,
they are in connection with few 100’s of
youth in India..
Via Cyber Means & Ways..

7. Surface Web
V/s
DeepWeb

11. Most of the times we only
open the websites listed in
popular search
engine’s

12. Deep Web Contents are
not listed in search
engines so we can not find
those in Google

13. Search engines only
stores data of static url like :-
LinuxAcademy.org
LinuxAcademy.org/contactus.html
LinuxAcademy.org/about.html
Static URL

15. How Antisocial elements gets access to
Deep web
Tor
Browser
As I am a cyber law student, I just want to alert you once again using this browser
may put you bhind the bars

17. Your IP Address is bouncing..

18. You are not able to open this website on any other browser..

21. Don’t try to install TOR, Checkout the warning on the
top…..

22. Payment Mechanism

23. Online Virtual Currency
(All Sort of Extortion Money – Ransom, is paid in Bitcoin online)

24. Conversion Rate
July 2010 -> 1 BTC = $0.08
15 Dec 2016 -> 1 BTC = $779

25. Bitcoin is a Cryptocurrency, a form of money that uses
cryptography to control its creation and management, rather than
relying on central authorities. Satoshi Nakamoto (the
creator of bitcoin) integrated many existing ideas from the
cypherpunk community when creating bitcoin.
Creation
In November 2008, a paper was posted on the internet under
the name Satoshi Nakamoto titled bitcoin : A “Peer-to-Peer
Electronic Cash System”.

27. How do Cyber terrorist’s identify & targets you….
What do you think who is
Biggest Hacker
in this world ??

28. Google, Google is the biggest Hacker as you saw
in previous slides that all data related with Surface web
is available with search engines.
So if you want to stay safe like China or Russia then you need to stop googling.
NSA is watching you so closely that you can’t imagine.
Best example of Google Data Mining is Google Traffic

29. Gabriel Weinberg launched DuckDuckGo as a
search engine that puts privacy first, rather than
collecting data for advertisers and security
agencies…
The search engine that doesn't track you.

30. Move on to...
Ransomware

31. The first ever computer virus was developed in
1986 by two Pakistani brothers in Lahore. The first
computer virus named "Brain" was designed by Amjad
Farooq Alvi and Basit Farooq Alvi

32. Variety of Virus available with us :
Virus
Worms
Trojans
Spyware
Malware
now Ransomware
Deep Web Users are not generating much money
so they created Ransomware (Ransom + Ware)

33. RANSOMWARE
Ransomware is a new type of virus that attempts to
extort money from a computer user by infecting and
tacking control of the victim’s machine, or the files or
documents stored on it.
Typically, the Ransomware will either
‘Lock’ the computer to prevent normal usage, or
encrypt the documents and files on it to prevent
access to the saved data.

35. RANSOMWARE
Only 15%chance is there to get data back
once it is encrypted using 128 Bit encyrption.
They demand Ransom in Bitcoins
using Dark Web, so their detection in
next to impossible.

36. RANSOMWARE
It will not attack on each every system,
Ransomware only encrypts the
system containing Data files.

37. TYPES OF RANSOMWARE
 The most common type displays messages
intended to coax the user into paying (Eg. Your
machine is infected)
 More destructive types encrypt files in the
system’s hardware (Encryption Ransomware)
 A new released version actually locks the
operating system (Lock Screen RansomWare)
 Master Boot Record (MBR) Ransomware

38. Screenshot of Ransomware
Attack in office of
CA Anshul Agrawal

41. HOW RANSOMWARE IS
DEPLOYED
 ATTACHMENTS- Most come through as ZIP
files or “invoices”
 ADVERTISEMENTS - Ad Network are often
targeted and exploited for these types of attack
 SECURITY HOLES - Java,Flash,Macros
(Word,Excel)

42. HOW RANSOMWARE IS
DEPLOYED
 Using Pen Drive on public computers in
Windows Environment.
 Using Pirated Windows & Pirated Antivirus
 Using Public Wifi / Open Public Network
 Using Internet Explorer

43. Free - Wifi

44. STRATEGIES
TO COMBAT RANSOMWARE
USE LINUX-
There have been no reported cases of
Ransomware taking over anyone's Linux based
operating system so why not join the millions of
people who have left Windows behind for a more
secure way of working.
CA’s can use Linux Machine as their DATA
Server

45. STRATEGIES
TO COMBAT RANSOMWARE
BACKUP YOUR FILES USING DROPBOX
or any other cloud Software
Backing up your files is still a good idea however for reasons
mentioned earlier such as protecting against disk failures, fires
and burglary.

46. Solution
 Right now we Don’t have any solution of high
end Ransomware like Cerber
 Quick Heal and other antivirus company are
providing solutions for lower end Ransomwares
which is approx 10%

47. WHAT YOU DO IF YOU ARE
INFECTED
 Power Down - Power off your computer
immediately
 Call For Help - Call person in charge of IT
 Describe-Everyone makes mistakes BE
HONEST about what happened,what
you saw and what you were doing
