Last years barcampmke was awesome, everyone had lots of fun and met some great people. Some of you might remember we had a little stand last year and ran the good old wall of sheep, well we liked it so much that this year we decided to become an official sponsor of barcampmke and expand our operations. This year we will not only be doing the the wall of sheep, but we will also be running a lockpick and tamper evident village, cat5 cable making couples contest, plus giving away free beer!! To get a free beer you have to either pick a lock from the village in under 2 minutes or reveal the secret message contained in a package secured with tamper evident lables, tape, lock seals, and tug tights, or beat your competitor to making a working cat5 cable! So sharpen up on your skills and win some free beer! See you at barcamp.

School is about to start back up for the year which gives us a great opportunity to give. So at the next meeting “9.7.12” if you bring in school/art supplies to donate in addition to the normal $5 dc414 donation you will get a “I HACK SCHOOLS” pin and the satisfaction of helping tomorrows generation to learn. So lets hack schools together!

Some ideas of stuff to give:
No.2 pencils
ballpoint pens “red and black”
Spiral-bound or composition notebooks
colored pencils
colored clay
non colored clay “grey”
backpacks
index cards
construction paper
glue
three ring binders
erasers
Pencil sharpener (hand-held with a top to collect shavings)
folders

dc414 donations bucket 2.0

A while back we started using a bucket to collect cash donations at meetings and for a while I have been wanting to trick it out. So I was keeping an eye out for things to add other then blinking lights, then cmoney came home with a powerball advertisement thing from her gas station that has a electric pendulum thing. I wish I had a picture of it but I didn’t have the for site to take one before I took it apart.

So anyway I got right to work on making the bucket pimp. First I made a little board

with a 555 timer blinking light circuit on it.

put some lights on it and wired the pendulum thing to it.

And hot glued it all to the lid of the bucket.

Here is what it looks like all together.

Ok thats it, I hope you think its cool. If you don’t, go fuck your mom.

August meeting awesomeness

Klaiviel started us off by giving us a nice show of binary key card hotel locks popular over seas, showed us a 3d printed key for one of his locks, explained pick proof locks from the 40s that are no longer used but highly effective and how to make them today using regular locks. Then he showed us why he is the second best key impressionist in the world, and made a working key for a lock right in front of us and giving us step by step instructions on how to do it our selves.

I stepped in and gave a quick demo of how I made our new and improved donations bucket which I will be making a blog post on later. Darkwind came packing with a alfa wifi antenna hooked up to a satellite dish! This made a killer directional wifi antenna, we took it up to the roof of bucketworks and got signals from all over including the moon 😛 Ngharo hooked it up to his lappy and cracked a few networks 🙂

After the roof party was over and we got back down stairs Castor gave a DEFCON20 badge hacking demo and showed us how to turn our badges into any other badge type we wanted, then showed us how to make the LEDs on the badge flash out words and stuffs. Then we all just started bull shitting and talking about up coming projects.

Cmoney couldnt make it out so I took a few picture that you can view here. Congrats to darkwind and faraday for winning the dc414 free junk giveaway!!

Good times with snmp

At the last meeting dw5304 gave a demo on snmp scanning and gaining access to things you shouldn’t have access to with a few home brew windows apps he coded up. Its been a while since I messed with snmp but his demo got me back into it, so I made a little python script to scan subnets for open snmp servers with the read/write string set to private. Here is the code:

#! /usr/bin/env python
import commands
from scapy.all import *

base = "69.2.1." #IP range to scan minus the last octet.
f = open('/tmp/snmp_output.txt', 'w+')
for i in range(1, 255):
ip = base+str(i)
print ip+"\n"
p = IP(dst=ip)/UDP(dport=161, sport=39445)/SNMP(community="private",PDU=SNMPget(id=1416992799, varbindlist=[SNMPvarbind(oid=ASN1_OID("1.3.6.1.2.1.1.1.0"))]))
pkt = sr1(p, timeout=1)
if pkt and pkt.sprintf("%IP.proto%") != "icmp":
p1 = pkt.sprintf("%SNMP.PDU%").split("ASN1_STRING['", 1)
p2 = p1[1].split("'", 1)
print pkt.sprintf("%IP.src%")+" - "+p2[0]
f.write(pkt.sprintf("%IP.src%")+" - "+p2[0]+"\n")
f.close()
print "\nDONE!!!!!!!!!!!!!!!\n"

Its a little hacked together and could use improvement but it works “feel free to send in any improvements you make”. It puts all the found servers IPs in /tmp/snmp_output.txt along with their system description enumerated via snmp. Here is a sample output:

69.1.117.87 - Ruckus Wireless Inc (C) 2006
69.1.117.156 - Ruckus Wireless Inc (C) 2006
69.1.117.190 - Ruckus Wireless Inc (C) 2006
69.1.117.193 - Ruckus Wireless Inc (C) 2006
69.1.117.203 - Ruckus Wireless Inc (C) 2006
69.1.117.221 - Ruckus Wireless Inc (C) 2006
69.1.163.92 - 24-port 10/100 + 2-Port Gigabit Switch with WebView and PoE
69.1.163.93 - Product: GW 4 FXS;SW Version: 5.80A.023.006

Once you find a few servers you can do snmpwalks on them and scour it for juicy info.
Here are some good OIDs to look for and/or set: *found most of this online & got some from dw5304

July meeting sweetness

July’s meeting was hot in more then one way! First I would like to thank genero again for his genorous donation for the raffle, which put a solid $200 in the 3d printer fund!! Also congrats to faraday for winning both the raffle and the Photoshop and WIN contest!! I know it took forever to pick a winner but we did it damnit 😛

ngharo started the demos off with talking about how he set up dc414’s new astrisk server using google voice as the SIP trunk! Then showed us how he set it up to use NMAP to scan IPs from asterisk and speak the results to you over the phone! Klaiviel took over and made Ngharo a case for his raspberry pi and a penny launcher with his sweet 3d printer. Then I stepped in and showed everyone how to send spoofed emails from the dc414 server using the email spoofer web app, then how to send spoofed txt messages using the same app 🙂 Then Tony used a SIP provider that allowed for spoofing CID to spoof a call to Vlad. Then dw5304 wowed us all with a SNMP scanner he made, showed us some of the results like accessing a routers, modems, and windmills!!

Here are some pics from the meeting thanx to cmoney and congrats to Castor for winning the dc414 free junk giveaway!

Here is Faraday with his raffle winnings!

Arduino Windows Attack Tool

Posted on by

A few meetings back I demoed my Arduino Windows attack tool. The Arduino and shield emulate a keyboard when plugged into a PC. Once triggered it opens the DOS edit program, writes some vbscript to a file called go.vbs, then runs it using wscript. The script downloads a payload from a web server. In the case of the demo it was a reverse shell that connects back to a nc listener from msf. I got the idea from the Social-Engineering Toolkit Teensy USB HID Attack but I dont have/want a teensy so I looked and looked for an Arduino version but all I could find was a USB keyboard lib, so my value add was porting it to the Arduino.

Here is the USB lib I used.

Here is the schematic for the shield: *I added a button on pin 12

Here is the code for the Arduino:

And there you have it, my Arduino Windows attack tool. Its a little messy and hacked together, but it works. Enjoy 🙂

Many thanx to SilkyPantsDan, Rancid Bacon, and Practical Arduino
