Doesn't seem to suport proxies that require authentication 220.127.116.11 13:16, 23 January 2009 (CET)
Ultrasurf and GTunnel and other tools released by the Global Internet Freedom Consortium were suspected to be a particularly pernicious type of malware due to its strange behavior and traffic sent to different locations. Wilders Security Forum explaines in detail what UltraSurf does:
UltraSurf and Gtunnel and likely all products put out by the Global Internet Freedom Consortium / Internet Freedom.org, are infact secret trojans. They give you a 1-hop proxy but use your system to launch attacks against financial institutions, government and energy websites, education, etc. Now here is the scary thing, if you are logged into one of these domains, like your bank, then they can get access to your authenticated session / cookie and potentially break right into your account, THROUGH YOUR OWN COMPUTER.
This is the summary of a test I've made with UltraSurf:
- changes security settings of Internet Explorer.
- scans a range of IP addresses.
- creates, modifies and deletes files.
- reads and modifies registry values

I've used Ultra Surf for years with no problem. Governmental institutions and such are just annoyed that people are able to bypass they're blockers to access the freeweb. For these blockers to be in place is against our (as Americans) Constitutional rights to the freedom of speech and religion. - Vignesh KM
