CAN BLOCKCHAIN BE HACKED PASSWORD ON A

What traditionally interests hackers? ThatвЂ™s right, cash resources. Over 10,000 Bitcoin nodes across the globe verify transactions. The reason why itвЂ™s essentially impossible to hack the Bitcoin network is because of its decentralized nature that prevents the Bitcoin blockchain from having a single point of failure. Bitcoin and Security: Can the Bitcoin Network be Hacked No, Bitcoin is considered hack-proof.

So, according to some leaders, the use of blockchain is an additional risk for the organization. Despite the fact that technology-based services and products are more resistant to all kinds of hacker attacks, for example, in 2019 alone there were seven major hacks towards well-known Exchanges, as a result of hacking the Upbit Exchange, almost stolen $ 50 million from customer wallets.We asked Dos Santos, can blockchain be hacked?Despite the many advantages, not all companies are in a hurry to implement blockchain, due to a lack of knowledge of the technology, reinsurance, or other reasons. To hack can also mean to program with exceptional skill.Now, hackers have focused their attention on cryptocurrency exchanges, miners, as well as solutions in the field of decentralized finance (or DeFi projects). In mining, nodes use much computing power to show that they are reliable enough to add information about new transactions to the database.Just weeks after Korean crypto exchange Coinrail lost 40 million through an alleged hack. Most of them get formed on blockchain technology that uses proof of work to check transactions.

Cm, and the popular international domain. The domain of this country is. In most developed countries, this type of fraud, like cybersquatting, is an illegal activity and punishable by law.In 2009, this type of fraud was especially common on sites in Cameroon. In addition to making money showing ads, the most dangerous thing for the user is that when they enter the name and password on a fake website, thinking that it is in the original, the scammer can obtain confidential data for greater unauthorized access to the information of other people or, for example, funds in cryptocurrency wallets. Therefore, a typosquatter can collect a fairly large percentage of вЂњlostвЂќ visitors on your site. They lured investors to fake ExchangesAttackers register domain names that are similar in content to the addresses of popular sites, or the most popular blockchain platforms, based on the carelessness of some users.

And they were created only to fraudulently obtain secret information about the user or show them an ad.Additionally, authorities in the Netherlands and London recently arrested a whole group of cyber criminals who managed to earn more than $ 27 million in Typequatting.As we see, attackers actively use this type of attack. Cm domain, which are essentially a fake copy of any site in the. Typosquatters have registered many sites in the.

Therefore, not a single case of a successful Sybil attack on crypto platforms has yet been recorded. It turns out that it is too expensive and inappropriate for attackers. For example, Bitcoin recognizes this type of attack due to the proof of work (POW) algorithm, which requires a node to spend a lot of resources on obtaining coins, which means that it is very expensive to have many nodes. Therefore, protection against them was established as the basis for the development of the cryptocurrency system project. But blockchain developers envisioned a similar type of attack. This is a method of attack in which a large number of nodes On the network they belong to a hacker, who by creating fake transactions or manipulating trustworthy transaction data during transmission, tries to cause a system crash.

Therefore, blockchain networks must deal with the implementation of protection methods that would make it impossible to take control of computing power.Most of the worldвЂ™s online traffic passes through Internet Service Providers (ISPs), which are intermediaries. They managed to steal $ 1.1 million and transfer the cryptocurrency to Coinbase.Although this type of attack is more likely on networks where the cost of capture is more affordable than on larger networks like Bitcoin, experts predict that such attacks will grow. In January 2019, the Ethereum Classic blockchain was the victim of hackers. In August 2016, the Krypton and Shift blockchains were attacked by 51%. (This scheme is known as double spending or reselling the same assets).Despite the great difficulties in implementing the 51% attack and its high cost, today there are several successful attacks on crypto platforms. This means that an attacker will be able to freely cancel already completed transactions and carry out double-spending attacks, which means that the user can send cryptocurrencies twice without the knowledge of the network.

The hackers found a loophole in a system that did not record the sending of money. So far, the main loss of funds has occurred due to bugs in the cryptocurrencyвЂ™s own software.As is the case with the Ethereum DAO, which was launched in 2016 on the blockchain basis. From 2015 to 2017, there were several more attempts to send spam to the Bitcoin network.Since Bitcoin was the first blockchain, many other networks have adopted similar security protocols, making this attack more difficult.The human factor and cryptographic vulnerabilitiesI would like to add that the human factor is the greatest vulnerability. The objective was to show that an increase in blocking is necessary (just at that time the discussion was ongoing about changing the size of the block), since in the current situation it is very easy to carry out a large-scale spam attack in network.

The security of wallets, exchange procedures, and third-party service accounts is a serious concern. The technology itself has fairly good protection, but its supporting elements are much less well protected. As a result, Ethereum Classic (ETC) was created, which was a continuation of the original Ethereum blockchain allowing for DAO hacking, and simply Ethereum (ETH), where the hack did not exist.Thus, the conclusion suggests that blockchain vulnerability is more related to the way people use it than the way itвЂ™s built. Then they had to solve this problem by doing a hard fork: they rewritten the blockchain records, from any time before the attack.
