Ukrainian CyberBerkut hacktivists claim that they have penetrated the internal network of Ukraine’s Defense Ministry and found proof that Kiev is getting secret data from MH17 crash investigators, including information which implies its involvement.

A document, posted on the website cyber-berkut.net, and allegedly downloaded from Ukraine’s Defense Ministry network, dates back to August 7 and appears to be signed by Colonel Igor Zorin, the chief of Ukraine’s air defense forces.
