There is absolutely no backdoor in Tor. We know some smart lawyers who say that it's unlikely that anybody will try to make us add one in our jurisdiction (U.S.). If they do ask us, we will fight them, and (the lawyers say) probably win.
We will never put a backdoor in Tor. We think that putting a backdoor in Tor would be tremendously irresponsible to our users, and a bad precedent for security software in general. If we ever put a deliberate backdoor in our security software, it would ruin our professional reputations. Nobody would trust our software ever again — for excellent reason!
But that said, there are still plenty of subtle attacks people might try. Somebody might impersonate us, or break into our computers, or something like that. Tor is open source, and you should always check the source (or at least the diffs since the last release) for suspicious things. If we (or the distributors) don't give you source, that's a sure sign something funny might be going on. You should also check the PGP signatures on the releases, to make sure nobody messed with the distribution sites.
Also, there might be accidental bugs in Tor that could affect your anonymity. We periodically find and fix anonymity-related bugs, so make sure you keep your Tor versions up-to-date.
2. The US Navy funded (maybe still does) Tor. Tor is useful for western allies & spies
3. Many of the developers live in western nations. While western nations like the US do have intel agencies who are interested in messing with Tor, it doesn't seem to have gotten to the point of shutting down the Tor Project or directly attacking their infrastructure much if at all, especially since Tor benefits the military as well.

There is also a research paper [1] and accompanying video [2].

I wonder what they may have to say about the soon coming next-gen onion services.

> The reason is that these function pointers are only accessed through an indirection layer, i.e., memory objects on the heap contain a pointer to a virtual table which is located in the code or data section of the application and contains a number of pointers to virtual functions. Since the attackers can only disclose the virtual table pointer, but not the virtual table itself, as it is not on the heap, they cannot disclose gadget addresses. Note that, when only ASLR is applied, the address of the virtual table is randomized with the same offset as the ROP gadgets. Therefore, such an attack can bypass ASLR but not selfrando.
> We therefore conclude that selfrando can thwart most real-world exploits. Attackers can only succeed in rare cases where they can disclose the complete heap and data section.
