Can you, K-S-V, help me decode this files ?

This has been known for some time. I wouldnt expect a fix any time soon.

Encryption scheme used is AES-128-CBC. i couldn't figure out the KDF (key derivation function) used to derive individual packet decryption key from global key using the salt block as shown above. KDF function is executed inside Alchemy VM (a method used to execute c code from ActionScript VM) which makes it very hard to reverse engineer from disassembled code.

Encryption of any kind (FlashAccess, Akamai Encryption) is not supported by this script. it can only process unencrypted fragments.
