Despite the claims on page 4 (the version of the 18th of June):

"by the top cryptography experts active in the area of block cipher cryptanalysis such as Schneier, Biham, Biryukov, Dunkelman, Wagner, various Australian, Japanese, German and Russian scientists, ISO cryptography experts, and all researchers always seemed to agree that it could be or should be secure."

I never claimed that GOST is a secure block cipher, following its related-key distinguisher (2 CPs, 2 keys, time of two encryptions).
