Many online attacks use Attack Vectors to exploit system weaknesses. DDoS, Eclipse, and a 51 Percent Attack are three common types. A DDoS, Distributed Denial of Service, attack, occurs when hostile hackers overload a network with requests. In blockchain, DDoS target crypto exchanges or mining pools. They disable a network's ability to serve users. Eclipse attacks control a single node inside an artificial environment. An attacker can manipulate communications with surrounding nodes to perform illegal transactions by isolating a node. When an assailant obtains control of 50% or more of a network's mining hashrate, it's called a 51 percent attack. The individual can submit fraudulent transactions, making the blockchain centralized. 51 percent attacks become difficult as a blockchain network increases in the number of honest nodes. Blockchain analytic tools such as CertiK’s Skynet help with online attacks by monitoring on-chain activity. To learn more about online attacks visit CertiK.com/resources.
