[OTR-dev] OTR homepage DNS poisoned?

 From Bell Canada the link in the Location: header takes me through a
couple of steps of tracking sites and then away over to any of several
spam/attack sites:
http://www.mega-brokers.co/lp-millionaireclub-brown/?coc=156&subc=w1ATM3TVTC6OC04PG7B7IRCK&paramc=golf-axe-Tw049LVw&paramf=MS%20-%20New%20Publisher%20-%20INTL
http://alwaysnew.feelfree4update.com/?pcl=3LbSqxsHPv14PjCURUDXDEdm0CHvCe21dottyrEp5Qo.&subid=102855_4a8f8983d90d5aba83b274e59952f44e&v_id=JMns7DFxzqZv1_WCWflzXTSG2mj3zOFVuYw-XLU3wFE.
etc.., which seem to rotate every few minutes.

 From Wind Mobile Canada, the landing page you're being given TCP RSTs
when I try to go to it, so good on Wind I guess.

It's strange that the DNS hijacking is only for some sites. Are you
sure it's targetting otr specifically? Can you maybe write a scapy
script to test thoroughly?


The landing site doesn't seem to be doing anything funny with
routing. My traceroute to from Bell:

That landing site is in Poland:
[kousu at galleon ~]$ geoiplookup 46.29.16.14
GeoIP Country Edition: PL, Poland
GeoIP Organization Edition: Sprint Data Center Sprint S.A.

[kousu at galleon ~]$ geoiplookup 195.22.126.213
GeoIP Country Edition: PL, Poland
GeoIP Organization Edition: EuroNet s.c. Henryk Kuc, Jacek Majak

Now, ooni mentions that Greece is doing DNS hijacking to block
gambling sites: https://ooni.torproject.org/post/eeep-greek-censorship/
but this doesn't look at all like government censorship, because of the
out of country spam sites. It looks like a spammer, or like someone
*trying to look* like a spammer.

Hm. Very mysterious.
