Oops. It looks like my beloved Twitter had a security issue. From a blog post yesterday:
We recently learned about — and immediately fixed — a bug that affected our password recovery systems for about 24 hours last week. The bug had the potential to expose the email address and phone number associated with a small number of accounts (less than 10,000 active accounts). We’ve notified those account holders today, so if you weren’t notified, you weren’t affected.
We take these incidents very seriously, and we’re sorry this occurred. Any user that we find to have exploited the bug to access another account’s information will be permanently suspended, and we will also be engaging law enforcement as appropriate so they may conduct a thorough investigation and bring charges as warranted.
