The document is a presentation by security researcher Nilesh Sapariya focusing on cyber security, emphasizing the importance of ethical hacking and the need for organizations to protect themselves from cyber threats. It covers various aspects of information security, including different types of hackers, OWASP's top vulnerabilities, and specific attack methodologies like XSS, CSRF, and IDOR. The talk aims to educate individuals on pursuing careers in information security and understanding the impact of these vulnerabilities.

23. Take Away :-

26. Black Hat Hackers

27. White Hat Hackers

28. Grey Hat Hackers

29. OWASP Top 10 – Stick to the basic
 https://www.owasp.org/index.php/Top_10_2013-Top_10

30. Deep dive into different attacks

31. XSS
CSRF
IDOR

32. Why XSS, CSRF and IDOR ?
Easy to find
High impact
Account takeover
Misunderstood by many

33. Why XSS ?

34. #Reason 1

35. #Reason 2 : $$$

36. Highest paid XSS Reward
 http://www.paulosyibelo.com/2014/07/the-unseen-facebook-bug-
bounty-2014-x.html

37. Why you should care about XSS ?
 So XSS is involved in two recent big HACKS i.e. Apple Developer +
Ubuntu Forums
 Story on :- How I Secured Dating Site- Stored XSS

38.  http://mytechblog.com/other/apple/apple-developer-website-hacked-what-happened/
 http://blog.canonical.com/2013/07/30/ubuntu-forums-are-back-up-and-a-post-mortem/

39. A Story Of How I Landed On Dating Site and
Secured it- Stored XSS
 http://shield4you.blogspot.in/2015/08/a-story-of-how-i-landed-on-dating-site.html

40. What is XSS ?
According to OWASP:-
 Cross-Site Scripting (XSS) attacks are a type of injection, in which
malicious scripts are injected into otherwise benign and trusted web
sites
 https://www.owasp.org/index.php/Cross-site_Scripting_(XSS)

41. #3rd Position @OWASP

43. Types of XSS
1. Stored XSS (Persistent)
2. Reflected XSS (Non-Persistent)
3. DOM XSS
4. TRACE XSS
5. Self XSS

44. 1. Stored XSS

45. 2. Reflected XSS

46. 3. DOM based XSS
 Basically all HTML documents have an associated DOM, consisting of
objects representing the document properties from the point of view
of the browse
 Whenever a script is executed client-side, the browser provides the
code with the DOM of the HTML page where the script runs, thus,
offering access to various properties of the page and their values,
populated by the browser from its perspective.
 The script code never gets to the server

47. E.g. Marktplaats- Bug Bounty – DOM based XSS - Fixed

49. Self XSS – Microsoft – NA

50. How they fixed it?

51. Demo:
bWAPP – Windows / VM machine
Burp suite-pro
Download link:-
http://sourceforge.net/projects/bwapp/

52. Set up:-
Attacker - Windows 8 Victim - Kali Linux
Internet
Consider this as public forum which is vulnerable to XSS

54. XSS Bug – Video

55. What is CSRF ?
 Wiki Says :-
http://en.wikipedia.org/wiki/Cross-site_request_forgery

56. Description
“Cross-site Request Forgery is a vulnerability in a
website that allows attackers to force victims to
perform security-sensitive actions on that site
without their knowledge.”

57. #8th Position @OWASP

58. Why CSRF so important ?

59. Highest paid bounty for CSRF: 10,000$
 http://yasserali.com/hacking-paypal-accounts-with-one-click/

60. Latest | News
 Pay pal Defaced by CSRF

61. Latest | News
 Facebook Hacked #CSRF
Link: http://pyx.io/blog/facebook-csrf-leading-to-full-account-takeover

62. Latest | News Blogger hacked # CSRF
 Blogger hacked # CSRF

63. Latest | News
 Blackberry CSRF leading to takeover user profile information
 http://shield4you.blogspot.in/2015/08/how-i-hacked-blackberrycom-to-update.html
 https://twitter.com/nilesh_loganx/status/630357485262663681

64. How this works ?

65. Anatomy of CSRF Attack
 Step 1: Attacker hosts web pages with pre-populated HTML form data.
 Step 2: Victim browses to attacker’s HTML form.
 Step 3: Page automatically submits pre-populated form data to a site
where victim has access (No verification done by server as browser is
performing request by checking cookies)
 Step 4: Site Authenticates request (with attacker’s form data) as coming
from victim
Result : Attacker’s form data is accepted by server since it was sent from
legitimate user.

68. Practical time 
bWAPP – Windows / VM machine
Burp suite-pro
Download link:-
http://sourceforge.net/projects/bwapp/

69. IDOR
I Insecure
D Direct
O Object
R Reference

70. #4th Position @OWASP

71. Highest paid bounty for IDOR - $20,000
 https://fin1te.net/articles/hijacking-a-facebook-account-with-sms/

72. Example 1:- As simple as that
 https://hackerone.com/reports/49356

73. Example 2 :- Delete Credit Cards from any
Twitter Account
 https://hackerone.com/reports/27404

74. Business Impact :-
 Sensitive information retrieval via parameters
 Deleting another user’s information
 Change delivery address of an order.
 View someone's else profile on behalf of authorised user
 Reclaiming other user’s data

75. Problem ?
1. No Secure Access model.
2. Numeric IDs.
3. Error message show and tell
4. Inconsistent ID sources
E.g. /abcd/test/123
/abcd/?test=123

76. Practical time 
bWAPP – Windows / VM machine
Burp suite-pro

80. Hold on !!!
The First reporter will get gift vouchers ;)

81. Online testing site – Test without going jail
TARGET 1
http://testasp.vulnweb.com (Forum - ASP)
Bug to find
1. Open redirection
2. Reflected XSS
3. Stored XSS

 This presentation is purely to give idea about one of information
security domain (web application) inside view.
 Its up to you to decide right carrier path according to your choice /
likes / dislikes
