Can You Access Tor on iOS Devices?

As M. Bison would say:

Thus far on my articles, I’ve mainly talked about Android devices, so maybe I’m showing a little bias.

The answer, of course, is yes! What I don’t know for certain is how good the various iOS apps are, but I can at least share some of the available offerings.

The three most popular apps available from the iTunes Store (at the moment) are called Onion Browser (by Mike Tigas), Red Onion (by Omar Mody), and VPN Browser, (by Art Fusion).

So, all three of these Tor-powered apps have high ratings on the iTunes Store itself, but those can be misleading – after all, the developers could’ve written them, right?

Since I don’t have a lot of personal experience using these apps, I turned to the community to see what they thought.  The site iPhone.informer features reviews of all kinds of different apps.

Even on there, Red Onion seems to have overwhelmingly positive reviews.  Onion Browser, on the other hand, received mixed reviews.  (Many users complained that it crashes frequently, which is also a problem with the desktop version).

As for the VPN Browser, it also has mainly positive reviews, with the exception of one, who said, “Every time I try to watch a video the app crashes.”  I almost never watch videos on Tor anyway, so that doesn’t concern me!

Internet Is Leaking!

What I’ve heard through the grapevine, on articles like The problem behind mobile Tor browsers’ IP disclosure, is that all three of these apps do work well in terms of being user-friendly, but on the downside, I’ve also heard that they have a serious problem with IP leakage (which would defeat the purpose of using them!).

On the plus side, the developers have apparently fixed these errors in more recent versions of Onion Browser and Red Onion.

Actually, an update to the above post says that the HTML5 multimedia leak and download-related leaks were fixed in later versions – hopefully that’s no longer a problem.

One of the ways in which IP addresses are leaked on mobile devices is via external HTML5 canvas image data, which is essentially what I was referring to in the May I Have Your Browser Fingerprint? post.

The current version of Tor (or the desktop version, at least) now warns you if a URL attempts to do this (Tor users are probably familiar with this message):

Even if the leak problem is “fixed,” I would still be cautious about using some of these mobile apps to access the Tor network.  There are other methods that can be used to deanonymize users, and the very act of using Tor raises suspicion…

Aww, but I was just looking at pictures of cute cats!! Anyhow, it seems that at the moment, no version of Tor is 100% anonymous, but if you’re careful enough, it may not matter.

Just don’t ask about buying any nuclear missiles, OK?  (I’m serious about that.)

Have you heard of the dark web? Simply put, it's the "hidden internet" built on networks like Tor. "Secrets of the Dark" chronicles my dark web experiences, but is also aimed at demythologizing it and teaching about it. Want to reproduce one of the "horror stories"?
