Bancor

Hackers steal $23.5M in cryptocurrency from 'decentralized' crypto exchange Bancor.

Attackers used a compromised wallet to steal $12.5 million of ether, $1 million of Pundi X, and $10 million of Bancor Network Tokens (BNT).

Bancor was able to mitigate the damages down to $13.5 million

No user wallets were compromised, but a wallet used to upgrade some smart contracts was compromised.
