+ Hiding Tor Platform Information
|
|
|
+
|
|
|
+0.0 Introduction
|
|
|
+
|
|
|
+The current Tor program publishes its specific Tor version and related OS
|
|
|
+platform information. This information could be misused by an attacker.
|
|
|
+
|
|
|
+0.1 Current Implementation
|
|
|
+
|
|
|
+Currently, the Tor binary sends data that looks like the following:
|
|
|
+
|
|
|
+ Tor 0.2.0.26-rc (r14597) on Darwin Power Macintosh
|
|
|
+ Tor 0.1.2.19 on Windows XP Service Pack 3 [workstation] {terminal services,
|
|
|
+ single user}
|
|
|
+
|
|
|
+1.0 Suggested changes
|
|
|
+
|
|
|
+It would be useful to allow a user to configure the disclosure of such
|
|
|
+information. Such a change would be an option in the torrc file like so:
|
|
|
+
|
|
|
+ HidePlatform Yes
|
|
|
+
|
|
|
+1.1 Suggested default behavior in the future
|
|
|
+
|
|
|
+If a user would like to disclose this information, they could configure their
|
|
|
+Tor to do so.
|
|
|
+
|
|
|
+ HidePlatform No
