Today I was told that if I use tor browser, hackers may access my Computer and can delete or copy files from my Hard Drive.
Is it really true? Can hackers access my computer If I use tor?
Thanks in Advance. :)
The TOR browser bundle is just one piece of (fairly) complex software and thus will contain bugs. It is based on the Firefox browser which regular receives bug fixes, even for remote code execution and this bug allowed an attacker to access local files in Firefox (but not TOR browser).
If it is possible to such bugs reside in a currently fully patched version of the TOR browser bundle but is not publicly known and I'm sure you will not get such information from the agencies which will use these bugs in the context of attacks or investigations.
Thus it is the best to not only use the TOR browser bundle but also use it from a system with no sensitive data on it. Also the system should not be able to reach any possible vulnerable systems inside your local network, because then typical Web 2.0 attacks like CSRF, XSS... in these systems could be used, like attacking the router or attacks using the local printer server.
