Hi,

I’m posting the crypto challenges on a single site for simple maintenance and centralization: http://crypto.israeltorres.org
Also I am just posting the announcements on Twitter instead of a ton of mailing lists and sites.
Enjoy and good luck!

2009 – April Minutes

Bartender — Sat, 11 Apr 2009 02:21:26 +0000

Hello IVUer’s

Thanks for coming to IVU the Friday before Easter (or Bunny & Eggs Day) . There were a whole 11 people there and you still missed out one some good fun. We talked about a slue of things and brought a new member up to speed on how things are intended to be run. Certainly not an impressive showing for new members, but in the end even they left the evening laughing and learning.

Israel, your cryptographic wonders and postings have mused yet another sole. Please keep up the good showing and maybe one day someone will be able to solve your challenge.

Until next month. Talk to you all soon. Please do not forget to join our mailing list.

2008 – September Minutes

admin — Wed, 01 Oct 2008 00:54:20 +0000

Irvine Underground’s September meeting was held at iHOP. For those who remember the early years of IVU this was the fourth meeting location we migrated to and we have come back for more pancakes!

The meeting is held upstairs at the iHOP across from SNA (John Wayne Airport) every second Friday of the month. This was the first meeting after DEF CON so the turn out was good and information was flowing.

IVU was at DEF CON in force and will be at Toorcon happening September 26th-28th in San Diego, California.

Israel Torres presented Crypto Challenge at this meeting going over last months challenge and this months challenge. For those unaware what crypto challenge is, a week or so before the meeting Israel posts to the IVU mailing list a challenge, if someone can crack the code they are presented with a treat. The tools are available on his website for the cracking and he is available online for questions pertaining to the contest.

Argus was the second presenter for the evening demonstrating and explaining TOR privacy and security. His slideshows are available here.

Basic outline of presentation (by aRgus)

Intro:
What is Tor/Onion Routing?
How does Tor Work?
Tools used in concert with Tor
Using Tor:
Anonymous browsing
Anonymous IRC
Using Tor for No-contact Network Recon
Web based attacks via Tor

Caveats:
How you’re still vulnerable
DNS Leaks etc.

Presentation response (by Bartender)

The presentation given was easily understood by novices and advanced users. It presented a good introduction of both concept and theory. Just demoing live practice or getting into the TCP/IP layer, this presentation clearly demonstrated a working knowledge of basics such as encryption, protocols, and the communication maps that Tor uses. Some of the listeners perked up when the it was realized that their ability to use Tor greatly increases their anonymity, security, and runs inline with or along with tools they may already be using.

Tor Project Abstract (from http://www.torproject.org)

“Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. (…more…)”

IVU raffled off the Headshot shirts featuring the agent blowing off the back of the hackers heads with a little challenge in the background prepared for the taking if anyone is willing. The shirt is aviailable here, and the challenge is at IsraelTorres.org.

Alf Watt – iStumbler

Alf Watt, creator of iStumbler gave a video conference presentation to Irvine Underground on September 9th 2005. This was our first video conference and the meeting went over well. Mr. Watt discussed his application and the future development of the project.

He took questions and answered them in details. The video of this presentation is not available. All future talks will be recorded accordingly and posted to the media archive page.

IVU Reborn!

We know you’ve been getting bored of the last rendition of the Irvine Underground site, so we’ve secretly been working the past few weeks behind the scenes… Hopefully you’ll like the new look as much as we do!

2007 – June Minutes

admin — Sat, 09 Jun 2007 00:47:34 +0000

This months IVU had a great crowd and great turnout. There were some new faces and some old friends who came out of the woodwork (OK jigsaw isn’t that old). The lock pick board was brought out and a handful of people brushed up on their picking skill sets throughout the evening.

The speech this night was given by Israel regarding how to properly use bump keys, without that is ruining anyones locks. The demonstration was so good even the pizza girl (A.K.A. S.T. Stone?) was able to get into the action and was able to bump 4 dead bolt locks in under a minute. Aside from that Harry showed off an alternative method to getting out of handcuffs using your car keys which surprised a few people.

With Defcon around the corner Bartender gave a sizable speech regarding his favorite hobbies, drinking beer and robots and when they came together under the event named “KegBot”.

Our raffle prizes this month where hands full of old hack-zines (which Chris? contributed back to the group as the first entry into the IVU library, thanks man!) and the grand prize being free pass to DefCon coming up in August!
