Smart contracts are a feature of blockchain and cryptocurrencies that allow for transactions without middlemen. Once the malicious code takes control of a relevant server, an “attacker could then pack the malicious contract into new block (sic) and further control all nodes of the EOS network.” Qihoo 360 warns that because of the distributed nature of blockchain technology, compromising one node can put the […]
