How I Learnt hacking in High School - BSidesLV - 2015
1. How I learnt hacking in
high school
Lokesh Pidawekar
2. The road ahead
● Why learn this?
● Creating the lab environment
● How to learn
● Caveats
● What next, opportunity?
● Conclusion
3. ● Security Engineer at Cisco Systems, Inc.
● Mastered Science of Information
Assurance from Northeastern University,
Boston (MA)
● Occasionally blog at
infosecforever.blogspot.com
● @MaverickRocky02

6. Penetration Testing
“Penetration testing is security testing in which assessors
mimic real world attacks to identify methods for
circumventing the security features of an application,
system or network1”

7. Why Pentest?
● Better (cost and effort) to find holes before attackers
exploit them
● Vulnerability assessment is not enough
● Requirement from compliance standards such as PCI
DSS2
● Increases the security of the computing resources being
tested
8. How did I start
● Curiosity
● Self phishing (My first endeavor)
● Reading blogs about breaking things
● Practicing techniques on old software
● Attending security meetups
9. And why?
● They don’t teach how to break systems in schools
but employers expect to defend all attacks as if we
know how to do it
● Cruising through the interviews and practical tests
● To develop penetration testing skill
10. Know thy self, know thy enemy. A thousand
battles, a thousand victories
- Sun Tzu
11. Let the show begins
Recipe for making a hacking lab
● Some virtualization platform
● installing required software for attack
● installing vulnerable software
● learning key concepts
12. The infrastructure
● Raspberry Pi, old laptop
● Virtualization Software -
o VMware fusion/workstation (if the
school is giving free license),
otherwise vmware player, Oracle
Virtualbox, Qemu

13. Attacking OS
Dedicated OS
● Kali Linux (Formerly known as Backtrack)
● Samurai WTF
● Santoku Linux
● Backbox Linux
● Pentoo
● Android Tamer (because it’s the age of mobile)
Recent developments to build frameworks for pentesting is exciting for e.g.
Pentestbox, Appie, Pentester’s framework etc.
14. Vulnerable Platforms for practice
Operating System Metasploitable 2
Vulnerability Specific
Images
Pentesterlab, vulnhub, CTFs images
Web Application WebGoat, BwaPP, DVWA, OWASP
Bricks
Mobile Applications GoatDroid, InsecureBankv2, DVIA
Custom Cloud based Hack.me
15. Learning, how to:
● Hacking is not point and shoot
● Fundamental from OWASP
● Security Researchers blogs e.g. Project Zero3, etc.
● Conference talks, videos (anyone heard of @irongeek or
@securitytube)
● Online courses on Coursera, udemy etc.
19. Security recruitment and hacking
● Hacking the company will put you in prison
● Companies are becoming more hands-on while
recruitment
● There is no dummies guide for cracking security
interviews
20. Wargames and Capture the Flag
● There are plenty of CTF games happening throughout the year (Check any
Con)
● Some CTF are live round the year
o http://overthewire.org/wargames/ - Challenges ranging from web app
to Linux command and overflows
o http://io.smashthestack.org/
21. Online challenges
The researchers, companies put online challenges for various attacks
● https://xss-game.appspot.com/
● https://github.com/yahoo/webseclab
● https://google-gruyere.appspot.com/
● https://github.com/cure53/xss-challenge-wiki/wiki/Older-Challenges-and-
Write-Ups
22. Responsible Disclosure
● Because we are white hats :)
● Builds trust between vendors
and security community
● Name and fame or even some
money

23.
24. Bug Bounty
Most of the companies have started to reward
researchers as part of bug bounty program
Example - Google, Facebook, LinkedIn etc.
Responsible disclosed vulnerabilities to Sony,
Prezi.com, Eventbrite etc.
There are platforms such as BugCrowd,
HackerOne, Synack, CrowdCurity etc. to
mediate for crowdsourcing bug bounty
25. Some guidelines to follow
● Write a concise report with proper steps to reproduce
the vulnerability
● Test security for the targets that are where you have
permissions explicitly
● Respect the vendor, do not indulge in malpractice
against them
● Do not copy paste other researcher’s report (there are
hell lot of bugs yet to be found)
26. ● Rapid skill development is key to success in security
● They can’t teach everything in class
● It’s not easy to gain experience of exploiting all
vulnerabilities in real world
● Defense can be designed well if we will know attacking
techniques
Conclusion
