Hello, i am NEW here, so i need good review, i am very good at hacking and securing linux.
Il find problem in 10 minutes and kill it from server, than we will find how it bypass into system and patch that think, also i give GRATIS firewall configuration to help you to prevent sucha think.
But you must understand Plesk or cPanel every often time got some 0day in wild because system is very complex with lots of soft included, and it is not hard to find bug in one of 200 services hes running ;)
As i say, award project, i don't want much money, i want to prove my self.
If you don't trust that i am good in this, give me access, il find you where is BOT/APP what is running issue, than you can AWARd project.
I am more than fair .
Cheers
