Just got an email from LibraryThing.
"During a security review, we found that LibraryThing suffered a data breach in November 2011. While no book data or financial information was taken, lost or changed, the hackers did take email addresses and encrypted password hashes for some accounts created prior to that date."
I skimmed that, as I'm all too prone to do, and thought "Geez. Target wasn't the only one to not bother telling its people about a breach." Then I read the LT blog post about it, more carefully.
Seriously? And now they make us change our passwords? Thanks a heap, Stay vigilant, y'all.
