  1. They also run a man-in-the-middle attack on Ethiopia Criminalizes VoIP Services · · Score: 1

    If you ask google's DNS servers the IP address of www.google.com you get this:

    bast4rd@winterfell ~% dig www.google.com @8.8.4.4

    ANSWER SECTION:
    www.google.com. 86399 IN CNAME www.l.google.com.
    www.l.google.com. 299 IN A 173.194.75.105
    www.l.google.com. 299 IN A 173.194.75.99
    www.l.google.com. 299 IN A 173.194.75.103
    www.l.google.com. 299 IN A 173.194.75.147
    www.l.google.com. 299 IN A 173.194.75.106
    www.l.google.com. 299 IN A 173.194.75.104

    Ethiotelcom has exactly 2 DNS servers to serve all its customers. If you ask one of them to resolve the same address you get:

    bast4rd@winterfell ~% dig www.google.com @213.55.96.148

    www.google.com. 400465 IN CNAME www.l.google.com.
    www.l.google.com. 115 IN A 213.55.98.242

    Query AfriNIC who owns that IP block and you get:

    bast4rd@winterfell ~% whois -f 213.55.98.242
    inetnum: 213.55.98.0 - 213.55.98.255
    netname: Ethiotelecom
    descr: Leased by Corporate Customers
    country: ET
    admin-c: ET4-AFRINIC
    tech-c: ET4-AFRINIC
    status: ASSIGNED PA
    mnt-by: AFRINIC-HM-MNT
    source: AFRINIC
    parent: 213.55.64.0 - 213.55.127.255

    What I find interesting about this is not necessarily that they are handing out poisoned DNS records, but that the IP address of the server presumably acting as the man-in-the-middle sits in a net-block they have designated as being: "Leased by Corporate Customers." To me this implies that Ethiotelecom isn't necessarily the one that is running this attack, but rather one of their "Corporate Customers," which begs the question: "What kind of a corporate customer would have the clout to make Ethiotelecom hand out poisoned DNS records?" My guess is that it's probably one of the intelligence services. Off course, for anyone who knows the very poor standards to which the country's IT workers are trained, this doesn't necessarily mean that they can, or that they are able, to do anything with this.

    Nothing new in this. There's like 8 layers of NATing before you can get out of this place. Not to mention a transparent proxy...
