Update: Several people are reporting that their Avios are back. Check your account and post if your Avios are still missing or if they have been returned. You may need to do a password reset to login to your account.
The Guardian covered the hack yesterday, but BA never even informed most people about what happened.

Several DDF members are reporting that their BA Avios accounts that should have points in them, are reflecting 0 Avios.
Apparently several BA accounts have been hacked and points have been used, so BA has preemptively drained the Avios out of many BA Avios accounts before more damage could be done.
If you do have trouble logging into your account if your account shows an incorrect 0 balance you can call British Airways at 800-452-1201 to re-verify your identity and regain full access to your Avios. It may take a day for online access to be restored, but if you do need to make a booking now they should be able to do it over the phone and waive the phone booking fee. Or you can just wait for BA to sort this all out within the coming weeks and they should send you an email to reset your password once they are done.
These attacks have been happening more and more often as of late. Hilton and United among other loyalty programs both have had their troubles with mass account hacking.
While the loyalty programs will always make good for points used by hackers, it’s always important to check your balances frequently for discrepancies and to maintain a strong password.
