- How do I deal with a compromised server? 13 answers
Just recently we noticed in our website (which was made by a 3rd party before) that the database was compromised. All data was appended by a small html information. What we did is to change all the sql access to parameterized version and change the password to an encrypted one.
But today same thing happened again and our server now is unresponsive (I'm trying to connect using teamviewer). How can I sanitized our server and prevent this from happening again?
