This document summarizes a talk on hacking given by Ivan Novikov. The summary includes: 1) Ivan has over 10 years of experience in security audits and has discovered over $1 million in bug bounties. 2) The talk covered different aspects of hacking including perimeter discovery, vulnerability discovery, exploitation, and post-exploitation. Case studies of hacking a gaming platform, e-commerce site, internet bank, payment system, and overall strategy were discussed. 3) Effective security requires knowing your perimeter, managing third party components, testing coverage, monitoring, and incident response.

3. “Gartner Says Worldwide
Information Security Spending Will
Grow 7.9 Percent to Reach $81.6
Billion in 2016”
2015 $75 B
2016 $81.6 B
This bullet definitely costs more than $156.6 B
It’s not a silver… Or the weight is about 269’400 tons

4. One simple
question

5. How it
works?

6. Why? Two important things since the 30s
No documentation (because of the Apple
and UX)
● Try to find documentation for Chrome
:)
● How to understand that it’s the bug but
not a backdoor
Closed source software (because of the
Intel et al.)
● What’s does “Intel inside” really mean?

7. Layer cake
How many layers do you know?
I spent last 10 year for the
security and don't sure that know
about all of them

8. Computer
science

9. Information
security

10. What exactly we are doing
Perimeter discovery
Vulnerability discovery
Exploitation
Post-exploitation
Risk analysis

11. Perimeter discovery NOC
Vulnerability discovery QA engineer
Exploitation Developer
Post-exploitation DevOps
Risk analysis Manager
What exactly we are doing

13. Main aspects
Perimeter. Just know your perimeter
3rd party components and software. Just know your requirements
Test coverage and test plan
Monitoring
Incident response

14. Case #1. Gaming platform (10+ games under the
roof)
A hacker found SQL injection because on gaming forum
The forum was connected to main players database
Hackers started to ‘;INSERT INTO stuff SET (<userid>, <rare-stuff-id>, …
Then they sold a lot of stuff for 30% price
Crash the entire game economy
No users report (all of them were happy)

15. Case #2. E-commerce platform, #1 local market
player
The point was to ship order with no payment somewhere
From the website to corporate network
Research how it’s going on inside with shipments
Hack the printer and just print an order on it
Staff there will use paper to deliver order ;)

16. Case #3. Internet bank
Client-side vector like really
Digital signatures everywhere
Stored XSS (Cross Site Scripting) in a news feed
JavaScript inject to send transactions when token installed on the client side
Use the same JS to hide these transactions from the web page ;)

17. Case #4. Payment system, a secured one
We tried to hack smth but were failed
Perimeter discovery process identified IoT devices inside corporate AS (thanks
BGP)
Found security cameras which protects private space (home of one of the
co-founder)
Hacked DVR device (Digital Video Recorded) inside home network
Found VPN from there to corporate network
Hacked power device in a datacenter to avoid isolation

18. Case #5. Hack them all!

19. Thanks!
