AO3 (Archive of Our Own) down for 2-4 weeks after security incident; user database theft not ruled out
The Organization for Transformative Works (OTW) took Archive of Our Own (AO3), the large fan-fiction site, offline on Oct 29 for what it first called maintenance, then said it had detected evidence of a security incident. OTW says no AO3 data was deleted and it does not currently believe the user database was stolen, but cannot rule it out. That database may hold usernames, email addresses, IP addresses and hashed passwords. AO3 does not collect real names, and donor data is in a separate system that was not exposed. The site is expected to stay down for at least two weeks and up to four.
