Leaked NSA Documents Reveal The Best Way To Stay Anonymous Online
The best way to stay anonymous online has been to use Tor, a special kind of web browser developed to help US government employees hide their tracks online.
But if you want to be properly anonymous, you need a combination of extra services and websites on top of Tor to avoid detection. There are plenty of online guides that offer advice, but it's always been hit and miss.
Now, leaked NSA documents provide a big clue on how to remain hidden. They show that the agency has trouble breaking certain methods of encryption.
Der Spiegel published a collection of documents that detail what systems the NSA has troubling decrypting. In the past documents have mainly focused on what the NSA is good at, not what it finds difficult.
The documents reveal that the NSA ranks targets according to how difficult they are to decrypt. There are five internal levels: One to five. Level one is known as "trivial," meaning it's pretty easy for the NSA to track targets or decrypt messages. But level five is "catastrophic," which essentially means that the NSA can't break the encryption.
The NSA says that reading someone's Facebook message is a level two "minor" task. And monitoring people using Tor is tricky, with the NSA classing that as a "major" level four problem.
So any level of anonymity classed as level five, known as "catastrophic," means that the NSA will find it near-impossible to break.
The NSA identifies one anonymity method which it warns is virtually impossible to break. Here's the method outlined in the leaked documents:
- Tor
- VPN
- CSpace
- ZRTP
Let's break that down: Tor is the special kind of web browser that helps people stay anonymous online by encrypting their web traffic. A VPN is a service that makes an internet connection more secure, using proxy servers to hide their real-world location.
CSpace is a kind of anonymous internet chat service that uses heavy encryption to protect any files sent over its network. And ZRTP, the last part of the method, is a kind of encryption for voice calls and text chats.
Combine the above stack of services together, using multiple kind of encryption, a special web browser, and a service to hide your location, and the NSA claims in its internal documents that it probably won't be able to read your messages. The leaked NSA document says that the encryption method results in a "near-total loss/lack of insight to target communications, presence."
