What to take from it.
WHAT TO ESTABLISH
How it happened How long it went unnoticed What it cost What would have prevented it
THAT SECOND QUESTION
If it went unnoticed for weeks, your monitoring is the gap.
WHAT TO CHANGE
Whatever allowed it.
Usually: updates, credentials, or something unmaintained.
WHAT TO DOCUMENT
The date What was found The entry point What you did What you changed
WHY DOCUMENT IT
If it happens again, that record is where you start.
And it may be needed if data was involved.
WHAT TO TELL OTHERS WITH ACCESS
What happened and what is now expected of them.
WHAT TO REVIEW
Your whole account, not just the affected site.
WHAT TO PUT IN PLACE
The routine that prevents recurrence.
THE HONEST ASSESSMENT
Most compromises follow neglect.
That is uncomfortable and it is also the reason it is preventable.
