An attack on the operating time of an Internet Service Provider (ISP) or their operations within a server-based system.
A routing attack is the type of malicious attack on Internet Service Providers (ISPs) that inhibits their operations. Usually, the aim of such attacks is not the ISP themselves but the server-based systems that run on them, for example, blockchain. So, the attack ‘breaks’ the network in such a way that communication between nodes is broken, effectively terminating the approved execution of transactions.
There are several types of routing attacks, and they are not limited to blockchain networks. Common examples of these are Denial of Service (DOS), Routing Table Poisoning (RTP), Hit and Run (HAR), and Packet Mistreating Attacks (PMA).
