Hacker Steals $30 Million Worth of Ethereum From Parity Multi-Sig Wallets
An unknown hacker has used a vulnerability in an Ethereum wallet client to steal over 153,000 Ether, worth over $30 million dollars.
The hack was possible due to a flaw in the Parity Ethereum client. The vulnerability allowed the hacker to exfiltrate funds from multi-sig wallets created with Parity clients 1.5 and later. Parity 1.5 was released on January 19, 2017.
Multi-sig wallets are Ethereum accounts over which multiple persons have control with their own keys. Multi-sig accounts allow owners to move funds only when a majority of owners sign a transaction with their key.
