Abstract
Like 100 million other Quora users, I awoke this morning to find an ominous email waiting for me that began: “We are writing to let you know that we recently discovered that some user data was compromised as a result of unauthorized access to our systems by a malicious third party.” Hot on the heels of the Marriott International hotel group breach that impacted half a billion users, the question and answer site has confirmed that its systems have been hacked leaving account and user information potentially compromised.
