iPHONE Apps for Information Security: article 201003

I have had the iPhone 3G for a little over a 1/2 a year now and in that time have accumulated some apps that could come in handy for the InfoSec Engineer / Analyst. In this write up I quickly describe one of my two folders of tools.

Screen shot 1:


RBL Status: A nice look up tool to see if a domain is on any one of 13 Black List services.

Nice Trace: A handy little trace route tool that constantly updates connection times to each hop; results can be emailed.

Scanner: A handy little tool that will automatically scan the network your device is connected and report back any other hosts it finds.

Scany: The closest to NMAP I could find. This is great little enumeration tool for open ports on systems.

Deep Whois: A great WHOIS lookup tool enumerate more info on a FQDN.

Base 2 Converter: Decimal to and from Binary conversion and ASCII to and From Binary conversion. This little tool comes in handy when I perform analysis and need help with data normalization.

ASCII2BIN: More conversion options than Base 2; HEX and Octal conversions too.

iRegex: Regex tool that verifies your expression for you and then you can email it off to cut and paste if needed. Handles POSIX and PCRE.

PING: The name speaks for itself but this tool also pings a subnet, performs traceroute, and telnet.

CP HexCalc: Calculator and converter for HEX, DEC, BIN, and OCT.

Subnet Calc: A nice calculator for carving up subnets.

RDP: A bear to use on the iPhone because of the screen size but does work in a pinch.

Folder 2 tools coming soon.

Penetration Testing Debate: Security Controls On or Off: article 201002

Take away: Topics: To turn off security measures for a penetration test or not.

I have just started the SANS 560 course Network Penetration Testing and Ethical Hacking and the initial reading brought some topics back to mind.
I have discussed and seen debates on such sites as Linkedin.com that covers the topic of whether or not to turn off security controls during a penetration test. My stance is against turning off such controls. If the security controls block such attacks doesn't that equate to a successful test of your security? I have heard and seen arguments against this such as, what if there is ever a misconfiguration and the attacker gets past the first levels of defense. To that my answer is; that is the purpose of change control, audit, and future testing. Organizations should not just test once and then feel pacified indefinitely. The amount and recurrence of change in an organization should dictate how often Pen Tests occur. At the least they should be once a year even if changes have not been made new found vulnerabilities could have developed in the systems used.

First virus removal of 2010: article 201001

Sitting at a friends computer trying to install McAfee right now so I figure I will jot down some notes about this virus removal.

When I arrived the virus had changed their desktop wall paper to a nasty lime green and red warning that that there system was infected. Pop ups were also being presented repeatedly that their system was infected a provided a link to install an AV program to have it removed.

I went to run McAfee but it was no where to be found. Instead bit defender showed available yet Bit Defender had never been installed.

I tried to run the system restore exec (rstrui.exe) but was told the executable was infected. I put a clean system restore executable on the computer and tried to run it but a message popped up saying it too had become infected.

I then ran rstrui.exe from a read only thumb drive; again I was told the file was infected. How could that be? I renamed the file to 1rstrui.exe and boom goes the dynamite. I restored the system to 2 weeks back installed multiple AV programs and root kit detectors and all came back clean.

Now I am always suspicious that a machine could be infected since encryption, polymorphism and zero days do exist but all apears fine now.

Bootable BackTrack 3 USB drive that allows Persistent Changes: article 200914

Take Aways: Using at least a 2 Gig USB stick create 2 partitions one for the BT3 OS the other to write files too.

Tools I used: 2 GB USB stick, Unebootin for Windows, a Desktop running XP and a laptop running a LIVE CD of BackTrack3

First giving credit where it is due: wirelessdefence.org Which is where I pulled my info on how to partition the USB stick and set it for persistent changes.

http://wirelessdefence.org/Contents/Backtrack3_USB_Howto.htm

There are several ways to do this and I am sure mine it not the most elegant but it worked for me.

I booted my Dell Inspiron 5150 with a live CD of BT3, inserted the USB stick and followed wirelessdefence's instructions for creating the partitions:

<>

1. Boot up your Linux machine (this is only required for initial installation a VMware machine will work fine).

2. In the Linux machine run "tail -f /var/log/messages" and insert the USB drive. In my case the following is displayed "[sdb] Attached SCSI removable disk" so we now know the USB device is sdb.

3. fdisk /dev/sdb

4. Command (m for help): p (to see what is on the drive).

5. If there are any existing partitions on the device delete them using d you will then be prompted for the partition number.

6. Command (m for help): n (to create a new partition)

7. Command action e extended, p primary partition (1-4): p (for primary)

8. Partition number (1-4): 1 (for first partition)

9. First cylinder (1-245, default 1): 1 or Enter (to start at the first cylinder)

10. Last cylinder or +size or +sizeM or +sizeK (1-245, default 245): +1024M (to create a 1Gb partition)

11. Command (m for help): t (to set partition type)

12. Hex code (type L to list codes): b

13. Command (m for help): n (to create a new partition)

14. Command action e extended, p primary partition (1-4): p (for primary)

15. Partition number (1-4): 2 (for the second partition)

16. First cylinder (126-245, default 126): Enter (to accept default)

17. Last cylinder or +size or +sizeM or +sizeK (126-245, default 245): Enter (to use the rest of the disk this will create a 1Gb partition if you're using a 1Gb disk)

18. Command (m for help): t (to set partition type)

19. Partition number (1-4): 2

20. Hex code (type L to list codes): 83

21. Command (m for help): p (to make sure there are two partitions of the type and size you are expecting)

22. Command (m for help): w (to write you changed to the disk, without this step nothing is actioned).


Mounting the new partitions in Linux:

1. Create 2 mount points e.g. mkdir /usb and mkdir /usb1

2. mount /dev/sdb1 /usb (mount the FAT partition). You made need to specify the file system e.g. mount -t vfat /dev/sdb1 /usb

3. mount /dev/sdb2 /usb1 (mount the Linux partition). You made need to specify the file system e.g. mount -t ext3 /dev/sdb2 /usb1

Note: If you are having trouble mounting any particular drive do a format on the windows partition or an fsck on the Linux partition prior to performing the mount.

< >

I don't know why but I did have trouble mounting my sda2 device and none of the suggestions above worked for me so I ran "mke2fs /dev/sda2" to format the partition and that did the trick.

Now that I had my 2 partitions I shutdown the my BT3 OS (this just worked best for me with adding and removing the USB stick) and pulled my USB stick out and placed it into my XP machine.

Now here is a jewel for making the USB stick bootable: UNetbootin from SourceForge. This app will automatically create a bootable USB drive for you with about 50 different OS types plus many over their versions! Of course BackTrack 3 is one of the options.

If you do not already have the ISO image downloaded it will go an snag it for you. In my case I had downloaded locally already so I clicked DiskImage and pointed it to my file.

In a manner of about 5 minutes I was ready to go.

I once again booted my laptop to the BT3, inserted the USB stick and once again looked to Wirelessdefence.com for assistance.

< >

1. mkdir /usb1/changes (manually create a "changes" folder on the Linux partition)

2. vi /usb/boot/syslinux.cfg (or use another text editor to open the file)

3. At the end of the APPEND line, under the mode you are planning to use e.g. KDE, add the following:

changes=/dev/sdb2

So, for the MENU LABEL BT3 Graphics mode (KDE)

"......rw autoexec=xconf;kdm" becomes "......rw autoexec=xconf;kdm changes=/dev/sdb2"

After you have made the changes save the file.

< >

I then rebooted the laptop choosing this time to boot to the USB key and "Boom, goes the dynamite"

The writable partition, for me, was under /mnt/sda2

FOLLOW UP Hacking Practical 1: Cracking WEP: article 200912

Quick Follow Up

My buddy was able to crack WEP 128 just fine on his Linksys today as well as another 3COM 7760. I went and verified and I was able to crack 128 as well on my Linksys. ODD!
