Hackers paid $15 to drain 2.5 billion from Binance in one hit.

00:06 Speaker A

So, as you know, hackers stole $6.3 billion from Binance and used a feature to take 40% of the stolen cryptocurrency in one transaction, reducing their chances of being caught. That was $15. This is what they're reporting.

00:18 Speaker A

$15 network fees to install an Ethereum wallet delegation. Blockaid estimates that single permission, approximately, enabled approximately 2.5 billion to be drained in one subsequent transaction.

00:29 Speaker A

The mechanism used Ethereum EIP-7702 wallet feature. Some real nerd stuff here.

00:33 Speaker A

EIP 772 lets a wallet authorize execution of another contract's code.

00:39 Speaker A

So CoinDesk's transaction analysis found valid authorization signed by the affected Binance wallet.

00:44 Speaker A

So,

00:46 Speaker A

I mean, the TLDR here

00:49 Speaker A

is that a $15 basically upgrade or permission was enough to hack $2.5 billion, which means maybe,

01:00 Speaker A

just maybe, uh crypto security is not ready for prime time. To give you a preview, I'm talking to Nathan from Anchorage on my Sunday podcast which will come out on YouTube, and, you know, they're one of the biggest custodians on the planet, a crypto bank.

01:10 Speaker A

We talked a lot about this and he really does believe that custody should be separated like it is in other markets.

01:15 Speaker A

We're going to see what the market does today, of course, uh over the weekend and into Monday.

01:20 Speaker A

Let's hope Bitcoin holds these levels and starts to push back up.
