The average data breach is thought to cost around $4.35 million as of 2022.īy 2025, it is thought that cybercrime will cost $10.5 trillion worldwide. When Epsilon, a marketing agency, was breached and the details of up to 75 clients including the likes of Best Buy and JPMorgan Chase were plundered. Over the years, we have seen companies lose huge amounts of money due to cyberattacks. Though most attacks focus on government agencies, supply chains, or critical infrastructure.Ĭyberattacks will often employ the use of malicious code, but many also rely on social engineering, with little more than a meticulously crafted email designed to trick an unsuspecting user into giving up the keys to the kingdom. A cyberattack can focus on an individual device or a whole network. Interestingly enough, since the blockchain has to be finite, it also means that most cryptocurrencies have a hard limit to how many can exist: Bitcoin for example has a cap of 21 million.Before we go any further, let’s first determine what constitutes a cyberattack.Ī cyberattack is a concerted effort by an individual hacker or group to disrupt computer systems, collect money, or steal data. Mining is validating new blocks and gaining access to the coins within. To summarize, the ledger records the creation and movement of coins in the blockchain. The ledger also shows when a coin changed hands, and who was involved in the transaction, putting the lie to the claim that Bitcoin is anonymous. The LedgerĮvery time a new coin is unlocked, it’s recorded in the cryptocurrency’s ledger, a massive file anybody can access at any time to see which coins were mined when and by whom. Also, because the blocks are chained in a linear fashion, you have to go from one to the next, you can’t pick one at random.
To unlock a new block you need to solve a complicated mathematical equation, which validates the block and adds it to the chain. For example, one block has 6.25 Bitcoin in it. In this metaphor, each link is a block, and each block contains a set amount of cryptocurrency.
