There are some problems with TOR (Some have solution): 1. Someone with enough resources can create and add to the network enough servers, especially entrance and exit nodes, to effectively nullify the TOR router. 2. Some web tools can have side channel attacks that break out of TOR and use the internet to get a specific resource. 3. Another popular side channel attack is fingerprinting the browser, best demonstrated by the EFF here: https://panopticlick.eff.org/ https://panopticlick.eff.org/ 4. TOR itself might have a bug or a backdoor, although this is getting a bit into the realm of conspiracy. This is of the top of my head, but I'm sure I missed some.
