I am running on Bitnami and AWS. Hackers have removed all the content on my MediaWiki and posted advertisements and junk.

Is there a way to roll back to my previous site version and stop unauthorized edits?

    As for reversing the changes, restore from a backup, that is one of your only options. – Ramhound Oct 5 '15 at 16:43
  • Doesn't MediaWiki have… edit history? – grawity Oct 5 '15 at 18:22

    I'm voting to close this question as off-topic because it is about administering self-hosted software. – ale Oct 6 '15 at 14:35
  • Webmasters or Information Security might be better places. Read the Help Center before posting. – ale Oct 6 '15 at 23:55

The way to do this is:

  • Check your backups.
  • Subscribe to the MediaWiki mailinglist (in order to be informed of security issues and other updates).
  • Install a new clean MediaWiki
  • Configure the user account to be created by you.
  • Restore the actual data from a backup (preferable from before the first spam links).
  • Only now make the wiki publically accesable.
