Strength In Numbers: An Entire Ecosystem Relies On Tor

This post is one in some blogs to complement our 2018 crowdfunding marketing campaign, Strength in Numbers. Anonymity loves company and we all have been safer and more powerful when we interact. Today Please contribute, and your gift will be matched by Mozilla. If the Tor Project, the Tor network, and Tor Browser were to disappear, what would happen? Not merely would an incredible number of global, daily users lose usage of Tor’s software, however the diverse ecosystem of personal privacy, security, and anti-censorship applications that rely on the Tor network would cease to function.

The same network and technologies that allow you to make an online search anonymously power the anonymity, circumvention, and privacy features of many third-party browsers, communications apps, secure operating systems, monitoring tools, and document posting apps. SecureDrop can be an open-source whistleblower distribution system developed by many Tor core contributors that media organizations can set up to accept documents from anonymous sources.

GlobaLeaks can be an open-source, free software tool intended to allow secure and anonymous whistleblowing initiatives. OnionShare is an open source tool developed by a Tor core contributor that lets you securely and anonymously share a file of any size. Many of these tools on the Tor network rely. Due to the Tor network, we can call attention to injustice with reduced risk. Many governments decided to block usage of the Tor network order ISPs to block the publicly shown IP addresses of Tor relays. In response, we developed bridge relays (“bridges”), that are Tor nodes that aren’t shown publicly, and are more difficult for governments to find and block thus.

As government censorship increases internationally, repressive regimes are more sophisticated in their strategies. Some governments employ a censorship technique called Deep Packet Inspection (DPI) to classify Internet traffic flows by protocol. DPI allows a censor to recognize and filter a multitude of tools, including Tor traffic, even though it attaches through a bridge.

In response to these types of censorship techniques, the Tor Project developed a versatile circumvention construction known as pluggable transports. Pluggable transports mask Tor traffic to make it look like other kinds of internet traffic, essentially making Tor traffic unseen to adversaries and resistant against DPI censorship strategies. The Tor Project is the foundation of the pluggable transports idea.

Popular circumvention and VPN tools like Lantern and Tunnelbear directly reuse Tor’s open source obfs4 pluggable transportation system for his or her own censorship circumvention services. Developers can take benefit of OONI’s dataset on internet censorship, likely the largest publicly-available reference to-date, to inform the circumvention methods they develop. Due to the Tor Project, we all have a robust ecosystem of options for circumvention in the real face of advanced censorship.

Most privacy safety tools provide end-to-end encryption, which can protect users against surveillance techniques that are focused on this content of their interactions. But these tools don’t protect metadata–information like: who talks to who, when, and exactly how much they say–which can be used to build behavioral maps (revealing a user’s contacts and the rate of recurrence with that they communicate, for example). As authorities censorship becomes more advanced, metadata surveillance has turned into a technique used to track individuals and their activities.

In reality, some human rights organizations report that many surveillance tools focus on metadata, and bad actors can use this metadata to aid further actions of oppression, such as general public doxing or defamation, arrest, and censorship. Our solution because of this problem is onion services. An onion service is a website or any other internet service that’s available through the secure Tor network. Take Debian’s onion service, for example: when you retain your Debian-based operating-system up-to-date via computerized improvements through Debian’s onion service, you ensure that the Debian Project cannot target your computer specifically.

If you update your Debian machine at home via your common, public, unchanging IP address relatively, in theory, a bad acting professional Debian administrator could target you specifically by shipping and delivery you a backdoored bundle. However when you update one’s body via Debian’s onion service, you feel an anonymous user accessing their anonymous services.

A bad professional would need to assault all users that access the onion service, which would likely be discovered and mitigated more than a targeted attack on a single individual quickly. Another example of the use of onion services is Haven, an application developed by the Guardian Project with Freedom of the Press Foundation and Edward Snowden. Haven can change any Android device into a motion, sound, vibration, and light detector, watching for unexpected guests and unwanted intruders.
