About this Event

(ISC)2 Melbourne Chapter Meeting – 22nd Sep 2020 (Tue)

“Unlimited WiFi: Bypass Captive Portals and Proxies with a Twist!”


Have you ever been stuck in the airport and run out of the one hour free WiFi? Have you ever been in a hotel that makes you pay for WiFi? Our talk, Unlimited WiFi, helps understand the common flaws within captive portals and proxies. On restricted networks, these methods can be used to exfiltrate information, where it may seem rather difficult, and download necessary exploits (please stop blocking exploit.db… makes pen testing a pain!).

Finally, we will talk about how we developed a mini-authentication framework over DNS, allowing us to turn on IoT devices when stuck in a plane and WiFi connectivity is questionable!

This talk brings in the concepts of misusing whitelisted software, writing scripts to bypass restrictions, writing your own authentication, and general software vulnerabilities. Our audience should gain a good understanding of the most common weaknesses within our target software and interesting ways to use the flaws they expose to our advantage!

Talk Outline:

1. Introductions + story of how we came about the idea

2. SQL Injections

3. MAC spoofing - Using MAC spoofing to get speed upgrades

4. IP Spoofing

5. Creds Stealing

6. SSH Tunnelling

7. DNS Tunnelling

8. DNS Tunnelling - Iodine Demo

9. Sub-domain Service Tunnelling

10. Outlook + Skype Tunnelling + Demo

11. Conclusion

How can I join the (ISC)2 Melbourne chapter? May I attend even if I am not a member?

Is my registration/ticket transferrable, can I order multiple tickets and what if I need to cancel?

One ticket per individual, with no transferring of tickets, makes it much more likely that building security will let you into the event and that everyone’s continuing education credits will be recorded correctly.
