Anonymous Blogging with WordPress and Tor

One of the great joys of working on Global Voices has been having the chance to work with people who are expressing themselves despite powerful forces working to keep them silent. I’ve worked with a number of authors who’ve wanted to write about politicial or personal matters online, but who felt they couldn’t write online unless they could ensure that their writing couldn’t be traced to their identity. These authors include human rights activists in dozens of nations, aid workers in repressive countries as well as whistleblowers within companies and governments.

I wrote a technical guide to anonymous blogging some months back and posted it on Global Voices, outlining several different methods for blogging anonymously. Since then, I’ve led workshops in different corners of the world and have gotten comfortable teaching a particular set of tools – Tor, WordPress and various free email accounts – which used in combination can provide a very high level of anonymity. The guide that follows below doesn’t offer you any options – it just walks you through one particular solution in detail.

You can feel free to ignore the “why” sections of the guide if you want a quicker read and if you’re the sort of person who doesn’t need to know why to do something. I hope to format this more prettily at some point in the future, allowing the “why” sections to be expanded and compressed, making the whole document a lot shorter.

If I’ve been unclear somewhere in the document or got something wrong, please let me know in the comments – this is a draft which I hope to clean up before posting it on Global Voices. Should you find it useful and want to disseminate it further, feel free – like almost everything on this site, it’s licensed under a Creative Commons 2.5 Attribution license, which means you’re free to print it on coffee cups and sell them, if you think there’s a market and money to be made.

My disclaimer: If you follow these directions exactly, you’ll sharply reduce the chances that your identity will be linked to your online writing through technical means – i.e., through a government or law enforcement agency obtaining records from an Internet Service Provider. Unfortunately, I cannot guarantee that they work in all circumstances, including your circumstances, nor can I accept liability, criminal or civil, should use or misuse of these directions get you into legal, civil or personal trouble.

These directions do nothing to prevent you from being linked through other technical means, like keystroke logging (the installation of a program on your computer to record your keystrokes) or traditional surveillance (watching the screen of your computer using a camera or telescope). The truth is, most people get linked to their writing through non-technical means: they write something that leaves clues to their identity, or they share their identity with someone who turns out not to be trustworthy. I can’t help you on those fronts except to tell you to be careful and smart. For a better guide to the “careful and smart” side of things, I recommend EFF’s “How to Blog Safely” guide.

Onto the geekery:

Step 1: Disguise your IP.

Every computer on the internet has or shares an IP address. These addresses aren’t the same thing as a physical address, but they can lead a smart system administrator to your physical address. In particular, if you work for an ISP, you can often associate an IP address with the phone number that requested that IP at a specific time. So before we do anything anonymous on the Internet, we need to disguise our IP.

What to do if you want to blog from your home or work machine:

a) Install Firefox. Download it at the Mozilla site and install it on the main machine you blog from.

Internet Explorer has some egregious security holes that can compromise your online security. These holes tend to go unpatched for longer on IE than on other browsers. (Don’t believe me? Ask Bruce Schneier.) It’s the browser most vulnerable to spyware you might inadvertently download from a website. And many of the privacy tools being released are being written specifically to work with Firefox, including Torbutton, which we’ll be using in a future step.

b) Install Tor. Download the program from the Tor site. Pick the “latest stable release” for your platform and download it onto your desktop. Follow the instructions that are linked to the right of the release you downloaded. You’ll install two software packages and need to make some changes to the settings within your new installation of Firefox.

Tor is a very sophisticated network of proxy servers. Proxy servers request a web page on your behalf, which means that the web server doesn’t see the IP address of the computer requesting the webpage. When you access Tor, you’re using three different proxy servers to retrieve each webpage. The pages are encrypted in transit between servers, and even if one or two of the servers in the chain were compromised, it would be very difficult to see what webapge you were retrieving or posting to.

Tor installs another piece of software, Privoxy, which increases the security settings on your browser, blocking cookies and other pieces of tracking software. Conveniently, it also blocks many ads you encounter on webpages.

c) Install Torbutton. Read about it and install it, following the instructions on the installation page. You’ll need to be using Firefox to install it easily – from Firefox, it will simply ask you for permission to install itself from the page mentioned above.

Turning on Tor by hand means remembering to change your browser preferences to use a proxy server. This is a muiltistep process, which people sometimes forget to do. Torbutton makes the process a single mouse click and reminds you whether you’re using Tor or not, which can be very helpful.

You may find that Tor slows down your web use – this is a result of the fact that Tor requests are routed through three proxies before reaching the webserver. Some folks – me included – use Tor only in situations where it’s important to disguise identity and turn it off otherwise – Torbutton makes this very easy.

d) Turn on Tor in Firefox and test it out. With Tor turned on, visit this URL. If you get a message telling you, “You seem to be using Tor!”, then you’ve got everything installed correctly and you’re ready for the next step.

It’s always a good idea to see whether the software you’ve installed works, especially when it’s doing something as important as Tor is. The page you’re accessing is checking to see what IP address your request is coming from. If it’s from a known Tor node, Tor is working correctly and your IP is disguised – if not, something’s wrong and you should try to figure out why Tor isn’t working correctly.

Alternative instructions if you’re going to be writing primarily from shared computers (like cybercafe computers) or you’re unable to install software on a computer.

a) Download Torpark Download the package from the Torpark site onto a computer where you can save files. Insert your USB key and copy the Torpark.exe onto the key. Using this USB key and any Windows computer where you can insert a USB key, you can access a Tor-protected browser. On this shared computer, quit the existing web browser. Insert the key, find the key’s filesystem on the Desktop, and double-click the torpark.exe. This will launch a new browser which accesses the web through Tor.

b) Test that Torpark is working by visiting the Tor test site with the Tor-enabled browser and making sure you get a “You seem to be using Tor!” message.

Torpark is a highly customized version of the Firefox browser with Tor and Privoxy already installed. It’s designed to be placed on a USB key so that you can access Tor from shared computers that don’t permit you to install software. While I recommend Torpark and use it when I travel, it is not formally supported by the folks behind Tor – they’re not happy that early versions of the program weren’t released with source code, which meant that it was impossible to determine precisely what Torpark did and how it used Tor’s source code. A more recent version of the program includes source code – it will be interesting to see whether Tor’s programmers offer their blessing of this version. Roger Dingledine of Tor has also indicated that he and his colleages are planning an open source version of a portable browser with Tor installed, but the timeline for this new project is unknown.

Step 2: Generate a new, hard to trace email account.

Most web services – including blog hosting services – require an email address so that they communicate with their users. For our purposes, this email address can’t connect to any personally identifiable information, including the IP address we used to sign up for the service. This means we need a new account which we sign up for using Tor, and we need to ensure that none of the data we use – name, address, etc. – can be linked to us. You should NOT use an existing email account – it’s very likely that you signed up for the account from an undisguised IP, and most webmail providers store the IP address you signed up under.

a) Choose a webmail provider – we recommend Hushmail and Gmail, but as long as you’re using Tor, you could use Yahoo or Hotmail as well.

Webmail is the best way to create a “disposeable” email address, one you can use to sign up for services and otherwise ignore. But a lot of users also use webmail as their main email as well. If you do this, it’s important to understand some of the strengths and weaknesses of different mail providers.

Hotmail and Yahoo mail both have a “security feature” that makes privacy advocates very unhappy. Both include the IP address of the computer used to send any email. This isn’t relavent when you’re accessing those services through Tor, since the IP address will be a Tor IP address, rather than your IP address. Also, Hotmail and Yahoo don’t offer secure HTTP (https) interfaces to webmail – again, this doesn’t matter so long as you use Tor every time you use these mail services. But many users will want to check their mail in circumstances where they don’t have Tor installed – for your main webmail account, it’s worth choosing a provider that has an https interface to mail.

Hushmail provides webmail with a very high degree of security. They support PGP encryption – which is very useful if you correspond with people who also use PGP. Their interface to webmail uses https and they don’t include the sending IP in outgoing emails. But they’re a for-profit service and they offer only limited services to non-paying users. If you sign up for a free account, you have to log into it every couple of weeks to make sure the system doesn’t delete it. Because they’re aggresive about trying to convert free users to paid users, and because their system uses a lot of Java applets, some find that Hushmail isn’t the right choice for them.

Gmail, while it doesn’t advertise itself as a secure mail service, has some nice security features built in. If you visit this special URL, your entire session with Gmail will be encrypted via https. (I recommend bookmarking that URL and using it for all your Gmail sessions.) Gmail doesn’t include the originating IP in mail headers, and you can add PGP support to Gmail by using the FreeEnigma service, a Firefox extension that adds strong crypto to Gmail (it works with other mail services as well.) The problem with Gmail is their signup process – to sign up for a Gmail account, you either need an invitation from an existing Gmail member, or you need to use your mobile phone to sign up for an account. Needless to say, we do not recommend using your mobile phone to request an invitation – it gives Google far too much personally identifiable information about you linked to that account.

Instead, if you already have a Gmail account, send an invitation to yourself. This will send you an email with a unique URL in it – copy that URL into a text editor or write it down. Turn on Tor, paste that URL into your browser and use it to sign up for the new account. Better yet, get an invitation from soneone who doesn’t know you – visit Bytetest or FatWallet, both of which maintain lists of free Gmail invitations.

A warning on all webmail accounts – you’re trusting the company that runs the service with all your email. If that company gets hacked, or if they are pressured by other governments to reveal information, they’ve got access to the text of all the mails you’ve received and sent. The only way around this is to write your mails in a text editor, encrypt them on your own machine using PGP and send them to someone also using PGP. This is way beyond the level of secrecy most of us want and need, but it’s important to remember that you’re trusting a company that might or might not have your best interests at heart. Yahoo, in particular, has a nasty habit of turning over information to the Chinese government – Chinese dissidents are now suing the company for illegal release of their data. Just something to think about when you decide who to trust…

b) Turn Tor on in your browser, or start Torpark. Visit the mail site of your choice and sign up for a new account. Don’t use any personally identifiable information – consider becoming a boringly named individual in a country with a lot of web users, like the US or the UK. Set a good, strong password (at least eight characters, include at least one number or special character) for the account and choose a username similar to what you’re going to name your blog.

c) Make sure you’re able to log onto the mail service and send mail while Tor is enabled.

Step 3: Register your new anonymous blog

a) Turn Tor on in your browser, or start Torpark. Visit and sign up for a new account by clicking the “Get a New WordPress Blog” link. Use the email address you just created and create a username that will be part of your blog address:

b) WordPress will send an activation link to your webmail account. Use your Tor-enabled browser to retrieve the mail and follow that activation link. This lets WordPress know you’ve used a live email account and that they can reach you with updates to their service – as a result, they’ll make your blog publicly viewable and send you your password. You’ll need to check your webmail again to retrieve this password.

c) Still using Tor, log into your new blog using your username and password. Click on “My Dashboard”, then on “Update your profile or change your password.” Change your password to a strong password that you can remember. Feel free to add information to your profile as well… just make sure none of that information is linked to you!

Step 4: Post to your blog

a) Write your blog post offline. Not only is this a good way to keep from losing a post if your browser crashes or your net connection goes down, it means you can compose your posts somewhere more private than a cybercafe. A simple editor, like Wordpad for Windows, is usually the best to use. Save your posts as text files.

b) Turn on Tor, or use Torpark, and log onto Click the “write” button to write a new post. Cut and paste the post from your text file to the post window. Give the post a title and put it into whatever categories you want to use.

c) Before you hit “Publish”, there’s one key step. Click on the blue bar on the right of the screen that says “Post Timestamp.” Click the checkbox that says “Edit Timestamp”. Choose a time a few minutes in the future – ideally, pick a random interval and use a different number each time. This will put a variable delay on the time your post will actually appear on the site – WordPress won’t put the post up until it reaches the time you’ve specified.

By editing the timestamp, we’re protecting against a technique someone might use to try to determine your identity. Imagine you’re writing a blog called “Down with Ethiopia Telecommunications Company!” Someone at ETC might start following that blog closely and wonder whether one of their customers was writing the blog. They start recording the times a post was made on and check these timestamps against their logs. They discover that a few seconds before each post was made over the series of a month, one of their customers was accessing one or another Tor node. They conclude that their user is using Tor to post to the blog and turn this information over to the police.

By changing the timestamp of the posts, we make this attack more difficult for the internet service provider. Now they’d need access to the logs of the WordPress server as well, which are much harder to get than their own logs. It’s a very easy step to take that increases your security.

Step 5: Cover your tracks

a) Securely erase the rough drafts of the post you made from your laptop or home machine. If you used a USB key to bring the post to the cybercafe, you’ll need to erase that, too. It’s not sufficient to move the file to the trash and empty the trash – you need to use a secure erasing tool like Eraser which overwrites the old file with data that makes it impossible to retrieve. On a Macintosh, this functionality is built it – bring a file to the trash and choose “Secure Empty Trash” from the Finder Menu.

b) Clear your browser history, cookies and passwords from Firefox. Under the Tools menu, select “Clear Private Data”. Check all the checkboxes and hit “okay”. You might want to set up Firefox so that it automatically clears your data when you quit – you can do this under “Firefox -> Preferences -> Privacy -> Settings”. Choose the checkbox that says “Clear private data when closing Firefox”.

It’s very easy for someone to view the websites you’ve visited on a computer by reviewing your browser history. More sophisticated snoops can find out your browsing history by checking your cache files, which include stored versions of webpages. We want to clear all this data out from a public computer so that the next user doesn’t find it. And we want to eliminate it from our personal computer so that if that computer were lost, stolen or seized, we can’t be linked to the posts we’ve made.

Some parting thoughts:

– It’s not enough just to protect yourself when writing to your own blog. If you’re going to post comments on other blogs using your “nom de blog”, you need to use Tor when posting those comments as well. Most blog software records the IP a comment came from – if you don’t use Tor, you invite whoever runs that site to track your IP address back to your computer. Tor’s like a condom – don’t practice unsafe blogging.

– Just because you’re anonymous doesn’t mean you shouldn’t make your blog pretty. The “Presentation” tab in WordPress has lots of options to play with – you can pick different templates, even upload photos to customize some of them. But be very, very careful in using your own photos – you give a lot of information about yourself in posting a photo (if the photo was taken in Zambia, for instance, it’s evidence that you are or were in Zambia.)

– If you’re really worried about your security, you might want to go a step further in setting up your Firefox browser and turn off Java. There’s a nasty security bug in the most recent release of Java that allows a malicious script author to figure out what IP address your computer has been assigned EVEN IF YOU ARE USING TOR. We don’t worry too much about this because we don’t think that or Google are running these malicious scripts… but it’s something to seriously consider if you’re using Tor for other reasons. To turn off Java, go to “Firefox -> Preferences -> Content” and uncheck the box for Enable Java.

– If you’re the only person in your country using Tor, it becomes pretty obvious – the same user is the only one who accesses the IP addresses associated with Tor nodes. If you’re going to use Tor and you’re worried that an ISP might be investigating Tor use, you might want to encourage other friends to use Tor – this creates what cryptographers call “cover traffic”. You also might want to use Tor to read various websites, not just to post to your blog. In both cases, this means that Tor is being used for reasons other than just posting to your anonymous blog, which means that a user accessing Tor in an ISP’s server logs doesn’t automatically make the ISP think something bad is taking place.

A final thought on anonymity: If you don’t really need to be anonymous, don’t be. If your name is associated with your words, people are likely to take your words seriously. But some people are going to need to be anonymous, and that’s why this guide exists. Just please don’t use these techniques unless you really need to.

    Remember, go to your DOS prompt and type EDIT…..then type your cleartext into the OLLLD EDIT program. Leaves fewer ghost files, .tmp files etc.

    Just one more way to flaunt the NSA……….

    Remember this, older is sometimes better, really old is sometimes the BEST. And EDIT is old.

  2. Woah.. I don’t know about TOR. I read major security issues and in a country where those vulnerabilities can have devastating effects, I’d steer clear of it.

    I went with Anonymizer last year and haven’t had any complaints. What’s good is that there systems are closed source and no logs are kept. I have heard about other companies sending supenas to get log info and provided with nothing but empty connection points.

  3. Ethan says:

    I’d recommend reading more closely, Jack. Tor’s issue are largely theoretical, lab-based attacks. Systems like Anonymizer rely on you trusting that single company – you have no way of verifying their code or their assertions that they keep no logs.

  4. Biodegradable Pants says:

    >I went with Anonymizer last year and haven’t had any >complaints.”

    Therefore, Anonymizer is 100% trustworthy. Like the Government.

    >What’s good is that there systems are closed source and >no logs are kept.

    How do you know this? Oh, ok, because they say so. Therefore it must be true.

  5. smaelz83 says:

    Tor is so good for hide our IP address but the con is that, sometime your connection be really slow since the information will go thorugh many computers before reach the target.

  6. I never heard of Tor before. Is that similar to using proxies or is it totally different?
