Let’s dive into a detailed explanation of crypto hacks they will help you to defend your crypto which you have earned hardly.

How Does Blockchain Security Work?

Blockchain technology has built up many security features which make it difficult for hackers to hack. But hackers can also take over a blockchain they can do this by stealing tokens from the sources like wallets or cryptocurrency exchanges. Is it difficult to attack a blockchain? Yes, it is difficult for hackers to attack blockchain because when blockchain runs it means that they don’t have a single point of failure. And cryptocurrencies also use advanced encryption technologies, consensus mechanisms, and public ledgers to increase safety and security.

All the transactions on the blockchain like Bitcoin are publically viewable.  Everyone who wants to run a node on the Bitcoin blockchain needs to download the entire transaction history of Bitcoin. Here the high degree of transparency helps to prevent malicious actions from sending invalid transactions.

Consensus mechanisms like the proof of work and proof of stake help the blockchain participants validate transactions without depending on a third party. Proof of work requires that computers solve challenging algorithmic puzzles to confirm the new transactions on the blockchain. But in the case of Power of stake validators must lock the crypto on the blockchain to confirm the new transaction.

The people who mine and stake on the blockchain are incentivized to play by the rules and regulations.  Validators and minors will only get awards if they perform their duties well. Many POS chains will slash validators’ crypto if there is any invalid transaction on detection. If someone wants to corrupt a POW chain they will need to have strong computing power to take over half of the network.

When it comes to PoS a hacker would need to stake or hack more than half of the total staking pool. Hacking a blockchain is possible but it is most unlikely on larger networks like Bitcoin and Ethereum as there are millions of investors for both of these cryptocurrencies. If the hacker is going to hack or corrupt the blockchain they have to focus on small altcoin contracts as it will be easy for them to hack small networks as compared to the larger networks.

How Can Blockchain be Attacked?

An attacker or a group of attackers can get access to a blockchain by controlling the majority of the blockchain’s computational power. If they get access to more than 50% of the hash rate they can easily introduce a new blockchain and this I called a 51% attack. It allows them to make changes to transactions that are not confirmed by the blockchain before they took access to the blockchain.

Transactions are then considered to be successful when six confirmation has been completed. For example, if you have transferred 1 bitcoin to your partner then the transaction will be recorded and confirmed in one block this is the first confirmation. That block data is recorded into the next block, then confirmed and the block is closed this is called a second transaction. This has to happen four more times for the network to process the transaction. Transactions that have not been processed after the first and second confirmations can be reversed to a 51% attack.

The attackers then will be able to use the tokens used in transactions that the network has not confirmed. They will then transfer the coins to anonymous addresses and then the altered blockchain would act however they had programmed it to work. Blockchain with a smaller number of participants has been then attacked in this manner but in the case of larger networks like Bitcoin and Ethereum, it makes it nearly impossible to attack due to the costs involved in acquiring 5% of the bitcoin or the staked crypto.

High-profile CEXs keep their crypto in the cold storage and most of them use high-security measures like two-factor authentication. However, major exchanges like coin base, Binance, and have suffered significant hacks. The CEX technology owns your crypto till you withdraw it to your private wallet. Some CEXs offer many insurance protections but there is never the guarantee they will reimburse customers during a hack.

Smart Contracts:

Smart contracts are blockchain programs that perform various functions without human intervention. A smart contract’s security is only good as its code. If developers miss the details in their smart contract a hacker can modify it and redeem crypto funds. DAO hack is the most common consequential smart contract hack. It refers to the contract-based governance structure prevalent in Defi.

Cross-Chain Bridges:

Cross-chain bridges are designed to migrate tokens from one blockchain to another blockchain. The goal of cross-chain bridge is very simple to understand the technology behind it has proven difficult to perfect. Many headline-grabbing crypto hacks in recent years have occurred in this novel technology.

Insider Hacks:

As it is understood that crypto is anonymous so are the hackers. Hackers are often the people who develop the protocols by themselves. Hackers leave a vulnerability and then wait until the amount they can steal grows before exploiting it is always a difficult task to identify the hackers.
