Hello, listers! I have detected that some IP addres of obfs3 briges have demasking WHOIS information.
For example obfs3 bridge with IP at range 192.36.31.0 - 192.36.31.255 (there are several bridges; I dont want to publish it at the list but can send by private messages if somebody wants). RIPE WhoIs tool at https://apps.db.ripe.net/search/query.html reports on this address: -------------------------- inetnum: 192.36.31.0 - 192.36.31.255 netname: ZWIEBELFREUNDE descr: Zwiebelfreunde e.V. ... address: Palaisplatz 3 address: 01097 Dresden address: Germany phone: +49-351-21296018 fax-no: +49-911-3084466748 abuse-mailbox: ab...@torservers.net remarks: --------------------------------- remarks: This network is used for research remarks: in anonymization services and remarks: provides Tor exit nodes to end remarks: users. remarks: --------------------------------- remarks: Dieser Netzblock wird zur remarks: Erforschung von Anonymisierungs- remarks: techniken genutzt und stellt remarks: Endnutzern Tor zur Verfuegung. remarks: --------------------------------- remarks: http://www.torservers.net/abuse.html remarks: --------------------------------- nic-hdl: MB22990-RIPE --------------------------- I think these whois data and remarks easy can demasking using of Tor network by ISPs. Also it may cause blocking of bridges IP in some areas. 194.132.208.0 - 194.132.208.255 IP range has the same problem. I wrote to Tor developers about this but have no answer received yet.
