Check Ubuntu Linux for Shellshock


Shellshock is a new vulnerability that allows attackers to put code onto your machine, which could put your Ubuntu Linux system at a serious risk for malicious attacks.

Shellshock uses a bash script to access your computer. From there, hackers can launch programs, enable features, and even access your files. The script only affects UNIX-based systems (linux and mac).

You can test your system by running this test command from Terminal:

env x='() { :;}; echo vulnerable' bash -c 'echo hello'

If you're not vulnerable, you'll get this result:

bash: warning: x: ignoring function definition attempt bash: error importing function definition for `x' hello

If you are vulnerable, you'll get:

vulnerable hello

You can also check the version of bash you're running by entering:

bash --version

If you get version 3.2.51(1)-release as a result, you will need to update. Most Linux distributions already have patches available.

ONIONSHARE - Send Big Files Securely and Anonymously


OnionShare lets you securely and anonymously share files of any size. It works by starting a web server, making it accessible as a Tor hidden service, and generating an unguessable URL to access and download the files. It doesn't require setting up a server on the internet somewhere or using a third party filesharing service. You host the file on your own computer and use a Tor hidden service to make it temporarily accessible over the internet. The other user just needs to use Tor Browser to download the file from you.

Features include:

  • A user-friendly drag-and-drop graphical user interface that works in Windows, Mac OS X, and Linux
  • Ability to share multiple files and folders at once
  • Support for multiple people downloading files at once
  • Automatically copies the unguessable URL to your clipboard
  • Shows you the progress of file transfers
  • When file is done transferring, automatically closes OnionShare to reduce the attack surface
  • Localized into several languages, and supports international unicode filenames
  • Designed to work in Tails, for high risk users

You can learn more about OnionShare here: https://onionshare.org/

To install OnionShare on Ubuntu, open a terminal and type:

sudo add-apt-repository ppa:micahflee/ppa

sudo apt-get update && sudo apt-get install onionshare

Before you can share files, you need to open Tor Browser in the background. This will provide the Tor service that OnionShare uses to start the hidden service.

Open OnionShare and drag and drop files and folders you wish to share, and start the server. It will show you a long, random-looking URL such as http://cfxipsrhcujgebmu.onion/7aoo4nnzj3qurkafvzn7kket7u and copy it to your clipboard. This is the secret URL that can be used to download the file you're sharing. If you'd like multiple people to be able to download this file, uncheck the "close automatically" checkbox.

Send this URL to the person you're trying to send the files to. If the files you're sending aren't secret, you can use normal means of sending the URL: emailing it, posting it to Facebook or Twitter, etc. If you're trying to send secret files then it's important to send this URL securely.

The person who is receiving the files doesn't need OnionShare. All they need is to open the URL you send them in Tor Browser to be able to download the file.



TAILS The Privacy Distro


TAILS, the anonymizing distribution released its version 1.1 about two weeks ago – which means you can download it now. The Tails 1.1 release is largely a catalog of security fixes and bug fixes, limiting itself otherwise to minor improvements such as to the ISO upgrade and installer, and the Windows 8 camouflage. This is one to grab to keep your online privacy intact.

Diagnosing Internet Problems


Recently I had been having some internet speed problems. There are several basic checks you can do yourself such as double checking your wired connections are all plugged in properly, making sure you are logged onto the correct wi-fi network :) and so on. You can even check to make sure your modem or router is not overheating (I once had one that was smoking).

So here are some tests you can run if you think you might have a problem, and what the heck, check it even if there isnt a problem so you know where you stand.

Pingtest checks your line quality by examining packet loss, ping rate and jitter rate. Low jitter means you have a stable connection.

Give yours a test here: http://www.pingtest.net/

I also like to use M-Labs Network Diagnostic Test (java required). Besides the basic up/down speeds, it also has sophisticated diagnosis of any problems limiting your speed.

Check it out here: http://www.measurementlab.net/tools/ndt

M-Labs also has NPAD test (Network Path & Application Diagnostics; java required) which is designed to diagnose network performance problems in your end-system (the machine your browser is running on) or the network between it and your nearest NPAD server (basically the last mile or so of your broadband). For each diagnosed problem, the server prescribes corrective actions with instructions suitable for non-experts.

Finally, you can also install NEUBOT (Ubuntu Linux, Windows, Mac). Neubot is a research project on network neutrality. Transmission tests probe the Internet using various application level protocols. The results dataset contains samples from various provides and is published on the web, allowing anyone to analyze the data for research purposes.

With this software you can also check to see if your internet service provider is throttling your internet speed for any reason.

Ubuntu users can easily install with DEB file...

http://releases.neubot.org/neubot-0.4.16.9-1_all.deb

At home I determined my wi-fi card was the problem and replaced it. At work, I found my ISP was throttling internet speeds when using Deluge (a bittorrent-like app). Knowledge is power!
