Open-source NAC with Packet Fence

Packetfence is an open-source project aimed at providing network access control.

One of the project leaders, Kevin Amorin, is here to tell us all about it!

Open source players show a knack for NAC

NAC ATTACK! - Researchers in Germany today demonstrated a tool that allows an unauthorized PC to disguise itself as a legitimate client in a Cisco Network Admission Control (NAC) environment, effectively circumventing the networking giant's end-point security strategy.

WRT54G Wireless Monitor

Using a WRTSL54GS we have hacked it to:

  • Sniff wireless packets while channel hopping using kismet_drone
  • Monitor bluetooth devices using the bluez stack and a hacked Linksys BT100 Class 1 device with an external antenna connector
  • Remotely monitor the 2.4Ghz spectrum with Wi-Spy and a specially ported remote agent called LINUXSpy

Live Demo!

Stories For Discussion

TWOVB aka The Week Of Vista Bugs - [PaulDotCom] - This is the year of the week of bugs! BONUS: Default Password List from the same site, kewl!

First Bug Released in TWOVB - [PaulDotCom] - I will borrow from J0hnny Long, and ask l33t or lame?

Windows ANI "Unspecified" Vulnerability - [PaulDotCom] - The link provided contains more resources, a patch installation file, and complete patch source code. Good, Bad, Indifferent? I think for individuals, a 3rd party patch is great. For organizations with more than a few desktops, its debatable. [Larry] - MS released the patch for this on Tuesday, a week early. QA issues anyone?. One otof the videos I was on this was great - ANI on desktop sends explorer on Vista into a crash loop.

USB 2.0 hub via 802.11g - [Larry] - Please buy these. It will make my job of sniffing your files, keyboard and any other USB transmissions easier. (Wireshark supports USB snooping).

Busting Bluetooth: Finding Bluetooth Sniffing Hardware - [PaulDotCom] - From what I can tell you can buy an off-the-shelf bluetooth dongle and turn it into a sniffer by flashing the firmware. However, this still requires a commercial application to sit on top of this in order to collect the packets. [Larry] I wonder how many other items are like this? Airpcap anyone?

Radio Shack Dumpster diving - [Larry] - While not technology, records disposal should be part of your IT (or other) security planning. Low tech hacking (dumpster diving) often yeilds interesting results.

Jikto leaked! - [Joe] - Billy Hoffman's Shmoocon presentation "JavaScript Malware for a Grey Goo Tomorrow" uncovered a URL to the Jikto source code and LogicX nabbed it. It is now out in the wild... (Here is a link to his presentation)

You too can be a porn star - [Larry] - Just leave naked pics of your vulnerable and then compromised machine. HACK NAKED!

"JavaScript hijacking" <3's Web 2.0 - [Joe] - "Fortify Software, which said it discovered the new class of vulnerability and has named it 'JavaScript hijacking', said that almost all the major Ajax toolkits have been found vulnerable. 'JavaScript Hijacking allows an unauthorized attacker to read sensitive data from a vulnerable application using a technique similar to the one commonly used to create mashups'"

Close to (Conference) home - [Larry] - Looks like the Navy lost 3 laptops with PII (Personally Identifiable Information) on them...right here, across the harbor here in San Diego. Password protection doesn't cut it!

WEP broken even more... - [Larry] - Now, 104 bit (weak!) with only 40-80K packets, with 50-95% reliability. All done in under 60 seconds.

Blackhat Europe Presentations Online - [PaulDotCom] - Its a good rule of thumb, when there are hacker cons you are not able to attend, read the presentations, watch the videos, or listen to audio, what ever they provide, its almost as good as going to the con!

Wifi Fuzzing Presentation with notes from BH EU - [PaulDotCom] - From the authors of Raw Glue AP
