Ethereum client Parity hacked leaving $150m of coins in limbo
A bug in cryptocurrency Ethereum’s second-most popular client, Parity, has frozen coins valued at $150m and left the initial coin offering of blockchain tech firm Polkadot in limbo. The glitch was triggered after a security hole was found in the technology that backs the cryptocurrency. Ethereum may have to be forked to release the funds, the second time such a measure has been taken in as many years after the currency's largest smart contract was hacked in 2016.

A security vulnerability in Ethereum’s second most popular client, Parity, has been exploited by this address earlier today.

All Parity multi-sig wallets have been frozen. That includes the Polkadot ICO and may include many others totaling around 500,000 eth, worth $150 million, according to some number crunching.
