Abhi If someone got into your website and defaced it, what will be your first step ?
Immediately take the site offline any have it only accessible to your IP so you can perform analysis.
Abhi Have you ever got into something ?
As an ethical hacker, yes ! 🙂
Abhi Where you able to diagnose it properly ?
Depends on the scope - do you mean my site being hacked, and me having to pick through it ? If yes, then "no" (thankfully).
