3.8.6 hacked!
 

hi, i upgraded to 3.8.6 2 days ago and upgraded to 3.8.6 patch level1 but hacked today.
all categories, threads etc. deleted and when i checked transaction and Transaction statistics pages i see a different page (title is: !C99madShell v. 2.0 madnet edition!) its a php shell script i think so.
