Aaron and Sjors discuss the COLDCARD hack: the bug itself, how it could have happened, and some reflections on having had Coinkite as a sponsor.

Note: If you're using a COLDCARD and still haven't moved your funds to a secure location, do this as soon as possible. (Also listen to the previous emergency broadcast.)
