The goal is to bring together enough information in one document for a beginner to get started. Visiting countless sites, and combing the internet for information can make it obvious your desire to obtain anonymity, and lead to errors, due to conflicting information. Every effort has been made to make this document accurate. This guide is image heavy so it may take some time to load via Tor.

It’s difficult to remember many passwords. First off it’s good to select a strong password manager. Keepassx is cross-platform, and has good security features, like encryption by password and using a keyfile. It also allows you to generate strong passwords, so if you’re not worried about memorization it’s good practice to let Keepassx generate secure random passwords.
It’s best not to use services that store your passwords in the cloud. If you need you can back up your encrypted password database, on a secure server, in an encrypted directory, and store your keyfile in a separate location.
Passwords for encryption and critical access should be prioritized. Even a long randomized password may not be a secure enough method. EFF recommends you try the diceware method, or basically randomly chain a number of words selected from a word list based on dice roles. Full details are available here.
Although it’s an annoyance, passwords are the ever present key to what matters most to you.
No service provider should be presumed to completely protect your privacy. Even if your VPN/Proxy or other ISP promises no logs, or identifiable information, time and time again information has been collected and used against those seeking anonymity. Open-Source technologies where you are able to examine source, yet trust is still ultimately placed in the hands of developers, are better than trusting a Government of other entity with your security.
Consider reading the Terms of Service any time you sign up for a service or install something.
Also remember that the times you use technology can be used to build a profile of your location for identification. Consider changing up your times of connectivity. On forums, chat and other services, it may be worthwhile to disable the notification that outwardly displays when you are on line or select invisible mode when applicable.
UFW (Uncomplicated Firewall) is a great general firewall for linuux
- sudo apt-get install ufw
- sudo ufw enable
- sudo ufw default deny incoming
as some malware may utilize outgoing traffic, like encrypted udp, it may be worthwhile to limit outgoing ports
- sudo ufw default deny outgoing
it may be better to specifically allow/deny the specific ports of concern.
- sudo ufw allow port/tcp
- sudo ufw allow port/udp
Then when you’re done check the status
sudo ufw status
you can see I’ve blocked some specific ports in this example
For more advanced configuration visit.
A MAC Address is a hardware specific identifier for you network interface. In some cases it may be useful to change your mac address to avoid detection.
sudo apt-get install macchanger
for a gui
sudo apt-get install macchange-gtk
heck your current mac addresses for future reference
for a random macaddress
sudo ifconfig wlan0 down
sudo macchanger -r wlan0
This will change the mac address to a random value
macchanger -e wlan0
will change the mac address but keep it as the same vendor. This can be useful if you’re spoofing your address but you don’t want it obviously coming from a device not on the network.
sudo macchanger -A wlan0
This will change the devices MAC to a random MAC of any kind, regardless of the original device.
sudo macchanger —mac=XX:XX:XX:XX:XX:XX interface
Will change to a specific mac address of your choice
You may want to write a script to start automatically on network manager start, and network manager shut down.
sudo nano /etc/init/macchanger.conf
description "change mac addresses"
start on starting network-manager
/usr/bin/macchanger -A wlan0
/usr/bin/macchanger -A eth0
/usr/bin/macchanger -A wmaster0
/usr/bin/macchanger -A pan0
#/usr/bin/logger wlan0 `/usr/bin/macchanger -s wlan0`
#/usr/bin/logger eth0 `/usr/bin/macchanger -s eth0`
you can switch out -A for -r or whatever other configuration you might want.
sudo nano /etc/network/if-post-down.d/random-mac
[ "$IFACE" != "lo" ] || exit 0
# Bring down interface (for wireless cards that are up to scan for networks), change MAC address to a random vendor address, bring up the interface
/sbin/ifconfig "$IFACE" down
macchanger -A "$IFACE"
- sudo chmod +x /etc/network/if-post-down.d/random-mac
- sudo service network-manager restart
The basic premise is monitoring the system for unusual activity. First is to keep an eye on the logs, and the next step is to consider an IDS like snort. There’s a learning curve, but here are some useful tools, that with some research can increase security especially if you allow others to access the system.
You may want to get yourself acquainted with some of the common security tools available. Here’s a good list, definitely nmap, tcpdump, netcat and wireshark are useful.
On first install of a linux operating system you should be prompted to create an encrypted LVM partition, and encrypt your home folder. This is a good start. For further security there is veracrypt.
Veracrypt is a fork of Truecrypt that is better at patching vulnerabilities. I see a lot of tutorials touting Truecrypt, and it’s in most package managers. However, you should download Veracrypt.
How to create a hidden encrypted volume with Veracrypt
Select Create Volume
Select Create an Encrypted File Container
Download at: torproject.org
All Tor network addresses will be followed with .onion, not .com. It is far more secure browsing .onion services.
In depth explanation of Tor by its head developer Arma.
Once you’ve download tor browser, expand the zipped file. Then
Configuring Security Settings
Privacy and security settings can be easily configured. Click on the Onion in the top left.
Select “Privacy and Security Settings” Adjust the slider to your desired level of security.
Depending on your security level selected in Tor, Noscript may not provide any advantage. That main advantage of Noscript is it’s easier to tailor allowing on specific sites, or for specific elements on the fly. Click the S in the Top Left next to the Tor Onion symbol and select forbid scripts globally. You should see a red line across the S. If you allow specific sites, you should check that the red line is there for those you do not allow. Allowing only specific sites may create a fingerprint of your activity. There are some advanced settings under options worth taking a look at.
in some cases if Tor is blocked or you wish to conceal the use of Tor a bridge can be configured. This makes it more difficult for an ISP to detect Tor. Bridges can help avoid censorship, and if your ISP Blocks Tor Traffic it is much more difficult to detect the nature of the traffic unless deep packet inspection is employed. It’s one of those things that since it’s there, might as well set it up as a per-cautionary measure and see if your connection is still, reliable and fast enough for your standards.
- Click Open Settings on the Pop-up Connection Box
- Click configure
- Select Yes to ISP Censors or Blocks
- obfs3 is fine, see below for information on other options.
- Most likely just skip use a local proxy
- Click connect
Optionally if Tor is already started you can:
- click the onoin icon in the top left of the browser and select
- Open Network Settings
- check My ISP Blocks Connections and hit OK.
- Use obfs 3 which is recommended, see next section on other types.
Pluggable Transports are extensions to Tor which utilize it’s pluggable transport API. These are more advanced ways to disguise traffic flow, for instance making it appear as skype traffic or utilizing a flash proxy. Many are now included in the Bridge Option Menu, so this is a good resource to learn more about the specifics. Some may require custom installation.
If you need to use another browser Firefox is preferred. Here are some configuration settings and extensions that can be helpful.
In the URL Bar enter: about:config
- geo.enabled = false
- geo.wifi.uri =leave blank
- network.http.accept.default = text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8
- network.http.use-cache = false
- network.http.keep-alive.timeout = 600
- network.http.max-persistent-connections-per-proxy = 16
- network.proxy.socks_remote_dns = true
- network.cookie.lifetimePolicy = 2
- network.http.sendRefererHeader = 0
- network.http.sendSecureXSiteReferrer = false
- network.protocol-handler.external = false #set the default and all the sub-settings to false
- network.protocol-handler.warn-external = true #set the default and all the sub-settings to true
- network.http.pipelining = true
- network.http.pipelining.maxrequests = 8
- network.http.proxy.keep-alive = true
- network.http.proxy.pipelining = true
- network.prefetch-next = false
- browser.cache.disk.enable = false
- browser.cache.offline.enable = false
- browser.sessionstore.privacy_level = 2
- browser.sessionhistory.max_entries = 2
- browser.display.use_document_fonts = 0
- intl.charsetmenu.browser.cache = ISO-8859-9, windows-1252, windows-1251, ISO-8859-1, UTF-8
- dom.storage.enabled = false
- extensions.blocklist.enabled = false
Other useful options:
- Disable all plugins: tools → addons → plugins
- Disable all live bookmarks: bookmarks → bookmarks toolbar → R/click latest headlines → delete
- Disable all updates: tools → options → advanced → update
- Enable ‘do not track’ feature: tools → options → privacy
- Enable private browsing, configure to remember nothing & disable 3rd party cookies: tools → options → privacy
it’s best to keep plugins at a minimum but here are some to consider
- HTTPS Everywhere
- Privacy Badger
- Close n forget
- Modify Headers
- User Agent Switcher
- Adblock plus
You may consider visiting ip-check.info to see what data your browser is sending.
It’s recommended to get a router compatible with an open source firmware. The two major recommended firmwares are Tomato and dd-wrt. In some cases Tor, or a vpn can be run directly on the router, and this can be useful if you find yourself forgetting at times to enable your desired connection. A backup router only used for specific connections may also be useful to swap in and out when secure connection is needed.. For the crafty, a Raspberry Pi can be configured as a local device to route connections through.
Installation is device specific navigate to either the Tomato or dd-wrt site for more information.
Tor: do your own research
The stand alone Tor daemon can be be found in the Ubuntu/Debian/Arch package manager.
sudo apt-get install tor
sudo pacman -S tor
However, you may wish to visit this link and add their PPA to get the latest version.
You can use Tor as a socks proxy once the service is started, either with the browser bundle or Tor daemon.
Navigate to the Network Settings, and Proxy section of the desired application.
Select Socks 4 Proxy and enter 127.0.0.1 port 9050.
This will route desired connections through Tor. TAILS automatically routes all connections through Tor.
Alternative to Tor, not as widely used since it requires some more dependencies and not as simple setup. i2p addresses always display as .i2p
Unlike tor i2p is a self contained network, it does not function as a proxy with traditional exit nodes. It is generally used to browse with the network of what are called eepsites.
Ubuntu/Debian based systems
- follow guide to add i2p to package list
- for ubuntu: sudo apt-add-repository ppa:i2p-maintainers/i2p
- for debian
- other see, and download necessary java files.
- sudo apt-get update
- sudo apt-get install i2p
starting i2p in terminal:
do not run as root or use sudo
- i2p router start
If you have issue connecting to .i2p addresses check configuration by visiting: localhost:7657/confignet
One main issue is your firewall or router is blocking connections. Click networking.
Basic port unblocking
- sudo iptables -A INPUT -p tcp —dport i2p port here -j ACCEPT
- sudo iptables -L
- sudo ufw allow i2p port here/tcp
- sudo ufw status
Other Anonymity Networks and Software
I don’t recommend these at all but will list one that has been reliable. You’ll have to search for more.
Unfortunately you should have no expectation of privacy on a free VPN but for one time use if you have no other choice it may be helpful.
Of the free VPNs seems most reliable, please delicately read terms of service and
utilize Tor on-top of the VPN with any sensitive content. Free VPNs are often banned
from posting on many services due to trolling. You can search for others but so far VPNBOOK just works.
Sometimes it may be necessary to use a proxy after the Tor exit node, for instance to appear in a desired location, or if exit nodes are banned on a service.
The setup is relatively simple on Linux.
- sudo apt-get install proxychains
- sudo nano /etc/proxychains.conf
- following ProxyList add
socks4 127.0.0.1 9050 #Tor must go first
socks5 ipaddress port
You will need to search for public socks proxy lists to populate.
start firefox in terminal: proxychains firefox
The best first step is stop the use of Windows and MAC OSX, and stick with Linux.
Locate the firmware model of the motherboard on your computer and flash it with a fresh version. Some deeper level attacks embed themselves in the firmware, so it’s good practice for a clean start.

Recommended: TAILS, Alternatives: Whonix, Liberté Linux and QubesOS
This guide shows how to install TAILS on a USB Drive from a Virtual Machine
- Download Virtual Box
- Download the latest extension package
- Double click on the extension package and it should open Virtual Box, click install
- Download TAILS
- Verify file identity with PGP
- Open Virtualbox and connect the USB drive
Click new in the top left:
- Next reboot you will be prompted if you wish to use persistent or not, only use when necessary.
Recommended base Operating Systems: Archlinux, or Kali, alternatives: Debian Mint Ubuntu
although just using Tails as a bootable OS and having some persistent storage is probably better than most can do in terms of hardening their base system.
Secure VM with Whonix and Virtualbox
- Download both Whonix-Gateway and Workstation
- Download Virtual Box
- You may want to verify the file identities using the Signing key see other sections on this.
Click file import appliance and select the Whonix Gateway .ova file:
You will keep both VM Windows open but all activities will be within the Whonix-Workstation VM Window
Disk encryption – LVM Encryption during install, encrypt home directory
Bleachbit – clearing day to day files (RAM wiping is experimental but worth it on shutdown)
secure-delete package – secure wiping content
Intro guides on hardening other recommended base systems.
(may be out of date look for hardening guides)
Consider using an OS like TAILS with minimal persistent storage and automatic memory wiping to make this easier.
Proceed with extreme caution, man pages are your friend.
easy, less effective
sudo apt-get install bleachbit
You can “Shred” files and folders from the file menu, and wipe free space, which may remove excess data that still exists, without pointers.
file→wipe free space
advanced, boot from usb/cd ideal when discarding a hard drive
go to dban.org download the dban.iso and either burn CD/DVD or write to USB and boot off the device.
Select “RCMP TSSIT OPS-II” for the deletion method
Select the drive
Prepare to wait 12+ hours
hard mode, more secure deletion that bleachbit, easier to use if you want to remove specific partitions or files, rather than complete wipe with DBAN
you will need to boot off a usb/cd if you wish to wipe your primary hard drive.
Properly deleting a drive will take time, if you’re in a hurry, you can at least use fast mode.
sudo apt-get secure-delete
If you’re wiping a disk
find the disk/partition name: should be /dev/sdxx
at this point if you haven’t already, consider encrypting the partition, see veracrypt.
wipe space considered free (-f is fast mode “insecure mode”)
sudo sfill /dev/sddisk#
if you need to clear swap space-
(-f is fast mode “insecure mode”)
- cat /proc/swaps
- sudo swapoff /dev/sddisk#
- sudo sswap /dev/sddisk#
- sudo swapon /dev/sdFdisk#
if you are strapped for time, use -m for 7 passes or -s for simple 1 pass “insecure mode”
sudo srm file
sudo srm -r /directory
At the end you may also be interested at the end to wipe memory on the system.
(-f is fast mode “insecure mode)
Try to at least encrypt the disk first, if you have time to spare, follow the instructions for disk erasure with DBAN.
Open the drive. Find the platter, score it, smash it. Then you will need to locate any memory chips which may store cached files, and destroy them as well. This is an important step, and can be missed easily. Remember not to dispose in normal garbage as it’s not secure. Consider alternate means of disposable for best measure.
Fun Fact: To “officially” destroy all remnants of magnetic data you’ll need to heat it to 1500 kelvin.
Older attack method recovering encryption keys stored in RAM. If possible use DDR3 or better memory. When not at the computer always shut down completely.
Consider using Bleachbit or more advanced sdmem to wipe RAM contents.
Keep in mind that your use of grammar, spelling and language can be used as identifying factors. It is possible to single you out based on your specific ways of communication and link you to other public content linked to your alternate identities. When attempting to communicate anonymously remember not to mention nicknames, locations favorite music, weather or any other information that can be used to reveal your identity. Something that seems mundane and friendly can quickly be used for identification.
JPG, JPEG, TIF and WAV files store EXIF data, or Exchangeable image file format, that can store sensitive information, including GPS-location, and the unique ID of the device used. It is recommended to always use the PNG format, and scrub any metadata, if you need to exchange an image. One option is the Metadata Anonymisation Toolkit that comes with TAILS, and also available at https://mat.boum.org/
No mail provider can be trusted completely no matter what their security claims are. Utilize PGP as often as possible and utilize an anonymous connection when connecting.
Protonmail is currently invite only and requires a wait time of anywhere from a month or more to get in. However, it’s a highly respected secure email solution. You can employ PGP and encrypted storage. They have a favorable location
Tutanota offers encrypted mail-storage and the use of a one time password, however PGP has to be done manually as there is no smtp or imap mail servers. They have a favorable location that is difficult to retrieve data from with legal orders.
While tor based mail providers have had a storied history. If PGP is utilized for all communications, the threat is eliminated. If you receive something compromising in plain text, don’t consider this information secure, and inform any correspondents to employ PGP.

Simple PGP On Linux
Ubuntu- sudo apt-get install gpa gnupg2
Arch- sudo pacman -s gpa gnupg2
- in terminal enter: gpg –gen-key or open gpa in terminal and it will prompt you to create one.
- follow the prompts
in most cases select option 1 – RSA and RSA (default)
select at least 2048 key size
key expiration, hit enter if not needed.
do not enter real information for contact (unless intended)
use a secure passphrase for the key
it will then ask you to move the mouse, type etc to create entropy
