Please note that it is especially important to change your passwords on the Wikimania wikis where you have accounts. These are non-SUL wikis and changing your SUL password will not effect a change on the Wikimania 2013 and 2014 wikis. Even if you never intend to edit those wikis again, your password and account could still hypothetically be compromised. I agree with others that the risk is very, very small; nonetheless, it is not non-existent.

LabsDB, launched in May 2013, is designed to give volunteers the ability to write tools and generate reports that make use of data from our databases in real-time. This supports bottom-up innovation by the Wikimedia community. As part of this process, private data is automatically redacted before volunteers are given access to the data. Unfortunately, for some of Wikimedia’s wikis[1], the database triggers used to redact private data failed to take effect due to a schema incompatibility, and LabsDB users had access to private user data for some user accounts in these specific wiki databases. As of October 1, 228 users have access to LabsDB, and the window of availability of this data was May 29, 2013 to October 1, 2013. This issue was discovered and reported by a trusted volunteer, and access to the data in question was revoked within 15 minutes of the report. We have no evidence to suggest that the private data in question was exported in bulk or used for malicious purposes, but we cannot definitively exclude the possibility. As a precautionary measure, we have invalidated all affected user sessions, and are requiring affected users to change their password on their next login. We have also sent an email notification to affected users with a confirmed email address. We regret this mistake. LabsDB is still a new part of our infrastructure, and we will fully audit the redaction process, so as to minimize any risk of a future mistake of this nature.

But normally notices of compromised passwords include standard language suggesting that users change their passwords for any other login where they've used similar information, in case the combination of name and password is sold or someone attempts to use their knowledge of you to access your information on other sites. Perhaps that is part of the e-mail notification the WMF sent; if not, it's good practice.

Even if you never intend to edit those wikis again, your password and account could still hypothetically be compromised. wikimania2013.wikimedia.org and wikimania2014.wikimedia.org are both part of SUL, so most users should use their CentralAuth account to login. They are slightly odd in that we don't give you a cookie for those sites when you initially login on another wiki, but with SUL2, you *should* get logged in when you visit the site. However, since SUL2 is relatively new, and you wouldn't get automatically logged in when visiting the site with the original SUL, I'm guessing many users visited the wikimania sites for the first time, logged in with their centralauth username and password, and continued on their way, which is one of the conditions where the local wiki stores the password hash used to initially create the account. So there is probably a higher number of users here who were notified, than on some of the other wikis. I agree with others that the risk is very, very small; nonetheless, it is not non-existent. Totally agree. Risker/Anne _______________________________________________ Wikimania-l mailing list Wikimania-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikimania-l
