If I worked for sly I would of done the following
Send unique Emms to cards to prepare them
Once u change encoding on specific channels or transponder the card replys back not subbed
Do firmware upgrade and block all non hw pairing boxs
Swap boxs out and then move sd premium channels to new counter measure and implement further anti cs measures like only 2 SIDS at a time in given time frame
Encrypt hw pairing section in box
Then encrypt whole flash
Will take along time to get round and even if some 1 does can't share more than 1/2 Sid at a time and couple that with the high ECM times they been deploying = cs but glitch as hell
Good job I don't work for them or no cs for anyone lmao
