Vector Attack 76

Tall the technologies developed, including blockchain, they have attack vectors that cyber criminals can take advantage of for their own benefit. In the crypto world, one of the least known attacks is the Vector 76 Attack o Vector Attack 76.

The arrival of digital currencies and cryptocurrencies brought with it a serious problem, the double spending. In centralized digital currencies, this problem is easily solved by having all control in one core. But in decentralized currencies like Bitcoin, the problem is much bigger. In fact, the design of Bitcoin manages to minimize the problem of double spending. We can even say that it “removes” it, but due to the decentralized nature of Bitcoin, there will always be some point of failure that can be used to double spend.

It is there where the Vector Attack 76 4 Confirmation Attack, take action. This double spend attack allows the attacker to include a double spend transaction in one block and use it to their advantage. This is accomplished by sending a self-built block for the network to give you a confirmation thinking the block is valid. In this way, the attacker can grab a certain amount of funds before the network can realize the problem. This attack was first described by the user vector76 on the Bitcointalk forum.

But, to understand the nature of this attack it is necessary to deepen the way in which it works, and that is what we will do next.
