found weird activities in the logs this morning. 500 files deleted from one account, database access, mail lists scanned. i think the hacker is still in the system. i'm panicking. what should i do now — shut down the site, notify the hosting company?
is there an emergency checklist? what do i do in the first hour? should i fully restore the server? can i recover the data? is my customers' (10k people) data at risk?
after that: police, insurance, post-mortem. should i do these in order? is forensic investigation expensive?
