00:00:00.690 --> 00:00:05.170
<v Aaron van Wirdum>Alright folks, this is not a new Bitcoin Explained episode. This is more of an

00:00:05.170 --> 00:00:10.060
<v Aaron van Wirdum>emergency broadcast. It turns out that the COLDCARD wallet, the hardware wallet

00:00:10.060 --> 00:00:13.000
<v Aaron van Wirdum>produced by our sponsor Coinkite, has a critical vulnerability.

00:00:14.880 --> 00:00:19.480
<v Aaron van Wirdum>This in particular concerns the MK3 and especially if it was used to generate a

00:00:19.480 --> 00:00:23.800
<v Aaron van Wirdum>single-sig wallet, but other COLDCARD types and setups appear to be affected to

00:00:23.800 --> 00:00:24.880
<v Aaron van Wirdum>different extents as well.

00:00:26.540 --> 00:00:30.380
<v Aaron van Wirdum>At the time I'm recording this, much is still unclear, but it is clear that

00:00:30.380 --> 00:00:34.720
<v Aaron van Wirdum>bitcoins are being stolen from these wallets by hackers that don't even need

00:00:34.720 --> 00:00:35.660
<v Aaron van Wirdum>access to the device.

00:00:37.380 --> 00:00:41.400
<v Aaron van Wirdum>So if you are using a COLDCARD to store your bitcoin, you should move them to

00:00:41.400 --> 00:00:44.060
<v Aaron van Wirdum>another wallet or somewhere secure as soon as you can.

00:00:46.600 --> 00:00:50.560
<v Aaron van Wirdum>Sjors and I will make a full episode on this issue later on, but for now we did

00:00:50.560 --> 00:00:51.940
<v Aaron van Wirdum>feel the need to tell you about this.

00:00:53.640 --> 00:00:57.000
<v Aaron van Wirdum>In the meantime, if you're looking for more information and updates about this

00:00:57.000 --> 00:01:02.740
<v Aaron van Wirdum>issue, Coinkite.com or blog.coinkite.com is probably the best place to go.

00:01:04.000 --> 00:01:04.620
<v Aaron van Wirdum>Thank you.
