[BTC] Linux Server/Router Exploit

Title says it all, It can be yours. or it can be a sales thread to someone elses. for some odd reason its extremely difficult to find someone that sells this without crazily overpricing it.
and I'm not talking about one of those 0day exploits that can pull thousands of bots in a minute. I mean a simple exploit, get 250 routers/small servers in 10 odd minutes.
Willing to spend $75.

getting a bot aswell wont hurt. but im not rich to spend more than $75 kek.
Don't have money right now, but Im expecting it to take a month or so to find a good deal. so yawp
