I have 2 sites on 2 different server and both are running on ee v3. Just checked today and both server have insane 9000gb of data transfered. I think someone has found some bug in v3 and is using my server for DDOS or something.
Even i am unable to update the server to ee4 as i get error
1gb-nyc3-01:~# wget -O migrate.sh https://rt.cx/ee3to4 && chmod +x migrate.sh
-bash: /usr/bin/wget: Permission denied
Someone plz help me solve this issue/
