One day when I was creating a pastie for some DevOps related discussion, and filtering out the organization related data….. it just occurred to what all internal information just gets added with the long logs getting pasted online for help.

someone pasted this on 20-Mar-2012 at

[hackersmag] (Adios Censorship, Hola ODDNS) Internet Censorship: state & solution

Posted in ABK Labs, Blogroll, security with tags , , , , , , , , , , , , , , , on April 11, 2012 by abhishekkr [20/Nov/2011, updated 11/April/2012]

They started with shutting down (supposed to be) bothering web portals, forcing them to change contentand even leak information about their users. When they found out they can’t (without any controversy) dominate all web services around the globe. They started taking DNS servers under control.

 InteXnet CensoXship
So, the problem why DNS Servers can be controlled currently is because of their structure.
DNS Servers have a tree-like hierarchical set-up.
It has few Root DNS Servers at the top, which contain the entire Internet Domain Name registration database and its relative IP. These are maintained by independent agencies, but maximum of those reside in U.S. and few others distributed over globe.
 Now, that is the main problem with this….. its based on a money exchange system architecture. You either mine namecoins for a domain name or buy them.

Jimmy Rudolf is out with ODDNS : Decentralized and Open DNS. It removes intermediaries dns servers from the scene removing their crippled dns resolutions.

Posted in ABK Labs, Blogroll, security with tags , , , , , , , , , , on April 11, 2012 by abhishekkr [31/March/2012]

to bypass such a system is real real easy… just get a link redirected from any in the batch of URL Shorteners, Page Translaters, Proxy or….. Simple get up a new machine on cloud and get it to bounce the URL back to desired URL.

Even if FB’s awesome team succeeds in blacklisting in ever growing services of proxy and url-shorteners.
This technique of theirs wouldn’t be able to catch your newly specially launched service before you a some decent response time.
