The CyberNews.com Investigation team’s analysis of Ethereum smart contracts – essentially code that helps online services send and receive payments – from shows that nearly 3,800 smart contracts have severe weaknesses that can allow cybercriminals to quickly steal 1 million dollars.
One of the most famous Ethereum smart contract vulnerabilities is what’s known as a reentrancy attack, which in 2016 allowed a cybercriminal to
steal $50 million.
We scanned 6 months’ worth of blocks from Ethereum’s blockchain and found that 3,779 contracts have 13 different types of vulnerabilities, including 4 high-severity vulnerabilities. The total value of these vulnerable smart contracts is
2,088 ETH, which equals $964,172.
