privacy tools

You are being watched. Private and state-sponsored organizations are monitoring and recording your online activities. provides knowledge and tools to protect your privacy against global mass surveillance.
Glenn Greenwald: Why privacy mattersOver the last 16 months, as I've debated this issue around the world, every single time somebody has said to me, "I don't really worry about invasions of privacy because I don't have anything to hide." I always say the same thing to them. I get out a pen, I write down my email address. I say, "Here's my email address. What I want you to do when you get home is email me the passwords to all of your email accounts, not just the nice, respectable work one in your name, but all of them, because I want to be able to just troll through what it is you're doing online, read what I want to read and publish whatever I find interesting. After all, if you're not a bad person, if you're doing nothing wrong, you should have nothing to hide." Not a single person has taken me up on that offer.

UKUSA Agreement
The UKUSA Agreement is an agreement between the United Kingdom, United States, Australia, Canada, and New Zealand to cooperatively collect, analyze, and share intelligence. Members of this group, known as the Five Eyes, focus on gathering and analyzing intelligence from different parts of the world. While Five Eyes countries have agreed to not spy on each other as adversaries, leaks by Snowden have revealed that some Five Eyes members monitor each other’s citizens and share intelligence to avoid breaking domestic laws that prohibit them from spying on their own citizens. The Five Eyes alliance also cooperates with groups of third party countries to share intelligence (forming the Nine Eyes and Fourteen Eyes), however Five Eyes and third party countries can and do spy on each other.

Why is it not recommended to choose a US based service?

Services based in the United States are not recommended because of the country’s surveillance programs, use of National Security Letters (NSLs) and accompanying gag orders, which forbid the recipient from talking about the request. This combination allows the government to secretly forcecompanies to grant complete access to customer data and transform the service into a tool of mass surveillance.
An example of this is Lavabit – a discontinued secure email service created by Ladar Levison. The FBI requested Snowden’s records after finding out that he used the service. Since Lavabit did not keep logs and email content was stored encrypted, the FBI served a subpoena (with a gag order) for the service’s SSL keys. Having the SSL keys would allow them to access communications (both metadata and unencrypted content) in real time for all of Lavabit’s customers, not just Snowden's.
Ultimately, Levison turned over the SSL keys and shut down the service at the same time. The US government then threatened Levison with arrest, saying that shutting down the service was a violation of the court order.

Key disclosure law - Who is required to hand over the encryption keys to authorities?

Mandatory key disclosure laws require individuals to turn over encryption keys to law enforcement conducting a criminal investigation. How these laws are implemented (who may be legally compelled to assist) vary from nation to nation, but a warrant is generally required. Defenses against key disclosure laws include steganography and encrypting data in a way that provides plausible deniability.
Steganography involves hiding sensitive information (which may be encrypted) inside of ordinary data (for example, encrypting an image file and then hiding it in an audio file). With plausible deniability, data is encrypted in a way that prevents an adversary from being able to prove that the information they are after exists (for example, one password may decrypt benign data and another password, used on the same file, could decrypt sensitive data).

Warrant Canary Example
A warrant canary is a posted document stating that an organization has not received any secret subpoenas during a specific period of time. If this document fails to be updated during the specified time then the user is to assume that the service has received such a subpoena and should stop using the service.

Warrant Canary Examples:

Mozilla Firefox

Firefox is fast, reliable, open source and respects your privacy. Don't forget to adjust the settings according to our recommendations:  WebRTCand  about:config and get the privacy add-ons.
OS: Windows, Mac, Linux, Android, BSD.

Tor Browser Bundle

Tor Browser is your choice if you need an extra layer of anonymity. It's a modified version of Firefox, it comes with pre-installed privacy add-ons, encryption and an advanced proxy.
OS: Windows, Mac, Linux, iOSAndroidOpenBSD.
Fingerprint image
When you visit a web page, your browser voluntarily sends information about its configuration, such as available fonts, browser type, and add-ons. If this combination of information is unique, it may be possible to identify and track you without using cookies. EFF created a Tool called Panopticlick to test your browser to see how unique it is.
You need to find what most browsers are reporting, and then use those variables to bring your browser in the same population. This means having the same fonts, plugins, and extensions installed as the large installed base. You should have a spoofed user agent string to match what the large userbase has. You need have the same settings enabled and disabled, such as DNT and WebGL. You need your browser to look as common as everyone else. Disabling JavaScript, using Linux, or even the TBB, will make your browser stick out from the masses.
Modern web browsers have not been architected to assure personal web privacy. Rather than worrying about being fingerprinted, it seems more practical to use  free software plugins like Privacy Badger, uBlock Origin and Disconnect. They not only respect your freedom, but your privacy also. You can get much further with these than trying to manipulate your browser's fingerprint.

While software like NoScript prevents this, it's probably a good idea to block this protocol directly as well, just to be safe.

How to disable WebRTC in Firefox?

In short: Set "media.peerconnection.enabled" to "false" in "about:config".
  1. Enter "about:config" in the firefox address bar and press enter.
  2. Press the button "I'll be careful, I promise!"
  3. Search for "media.peerconnection.enabled"
  4. Double click the entry, the column "Value" should now be "false"
  5. Done. Do the WebRTC leak test again.
If you want to make sure every single WebRTC related setting is really disabled change these settings:
  1. media.peerconnection.turn.disable = true
  2. media.peerconnection.use_document_iceservers = false
  3. = false
  4. media.peerconnection.identity.timeout = 1
Now you can be 100% sure WebRTC is disabled.

How to fix the WebRTC Leak in Google Chrome?

There is no known working solution, only a plugin that is easily circumvented. Please use Firefox instead.

What about other browsers?

Chrome on iOS, Internet Explorer and Safari does not implement WebRTC yet.  But we recommend using Firefox on all devices.

Stop tracking with "Disconnect"

Block Ads with "uBlock Origin"

An efficient wide-spectrum-blocker that's easy on memory, and yet can load and enforce thousands more filters than other popular blockers out there. It has no monetization strategy and is completely open source. We recommend FireFox but uBlock Origin also works in other browsers such as Safari, Opera, and Chromium. Unlike AdBlock Plus, uBlock does not allow so-called "acceptable ads".

Hinder Browser Fingerprinting with "Random Agent Spoofer"

Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.

The NSA has built an infrastructure that allows it to intercept almost everything. With this capability, the vast majority of human communications are automatically ingested without targeting. If I wanted to see your emails or your wife's phone, all I have to do is use intercepts. I can get your emails, passwords, phone records, credit cards. I don't want to live in a society that does these sort of things... I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under.

We all need places where we can go to explore without the judgmental eyes of other people being cast upon us, only in a realm where we’re not being watched can we really test the limits of who we want to be. It’s really in the private realm where dissent, creativity and personal exploration lie.
