ALERT: treat any content from dentsu-inc.com with extreme caution
Reports have been received that there have been attempts to sell malvertizements, with contact being made by email, with the correspondent using the email address @dentsu-inc.com.
Dentsu is a large Japanese agency, but their real domain is @dentsu.com (no inc).
dentsu-inc.com was registered, not surprisingly, by the infamous Estdomains Inc. The domain was created on 24 June 2008.
1. The person selling the advertisement resisted requests to talk on the telephone.
2. Dentsu may be a very well known agency, but dentsu-inc.com is *not* the URL that the legitimate company uses.
3. Estdomains Inc is the registration service that was used for dentsu-inc.com.
4. The domain is only a few months old.
5. Estboxes.com supplies the nameservers:
Query for dentsu-inc.com type=255 class=1
dentsu-inc.com NS (Nameserver) managedns1.estboxes.com
dentsu-inc.com NS (Nameserver) managedns2.estboxes.com
dentsu-inc.com NS (Nameserver) managedns3.estboxes.com
dentsu-inc.com NS (Nameserver) managedns4.estboxes.com
managedns2.estboxes.com A (Address) 126.96.36.199
managedns3.estboxes.com A (Address) 188.8.131.52
managedns4.estboxes.com A (Address) 184.108.40.206
managedns1.estboxes.com A (Address) 220.127.116.11
This does not match with the services used by the legitimate dentsu.com web site:
Query for dentsu.com type=255 class=1
dentsu.com NS (Nameserver) gatekeeper.isid-us.com
dentsu.com NS (Nameserver) gatekeeper2.isid-us.com
dentsu.com NS (Nameserver) ns.dentsu.com
dentsu.com NS (Nameserver) ns1.dentsu.co.jp
gatekeeper2.isid-us.com A (Address) 18.104.22.168
ns.dentsu.com A (Address) 22.214.171.124
gatekeeper.isid-us.com A (Address) 126.96.36.199
6. The IP address for the server hosting dentsu-inc.com is 188.8.131.52 (which is owned by the UkrTeleGroup in the Ukraine). The URL itself automatically redirects to the legitimate Dentsu site, so if you don't look at what is going on behind the scenes, all you will see is a commonly experienced redirect. It is *what/who* is redirecting you that is important in this case, not your end destination.
