Did you know that anyone can carry out a transaction from your wallet by knowing the wallet address only and without the need for the wallet’s secret key or phrase? There is a type of attack known as Zero Transfer Phishing that is considered one of the worst phishing attacks in the crypto field because of the ease of doing it by the attacker, and the ease of Falling into it on the part of the victim. This attack currently targets millions of crypto wallets on different networks. How is this attack carried out? How do you protect yourself from it? First, there is a function in the Ethereum virtual machine (EVM) called transferFrom(). This function allows transactions from your wallet to another wallet via a third party. This means that a third party, such as a smart contract, can withdraw from your wallet via this function. Provided that prior approval is obtained from the wallet. There are many uses for this function, including “Swap” currency exchange transactions via decentralized platforms, as it allows the smart contract to withdraw a balance of X currency from your wallet; In exchange for obtaining a balance of Y currency. This function is used on other networks such as BNB Chain, Tron, and others. But at the same time; This function allows anyone to make a transaction from another person's wallet without their permission if the transaction amount is 0. What is the purpose of this if the transfer is worthless? The goal is to poison the wallet's transfer history to trick the wallet owner into making a transfer to the attacker's wallet. This is called an address attack. Poisoning.How does this attack occur? Firstly, the attacker searches for active addresses by searching through the blockchain, and active wallets are often targeted in stable currency transfers. Secondly, the attacker creates wallet addresses whose beginning and end are identical to the addresses of the targeted victims. How does this happen and the wallet addresses are generated in a manner Random? In fact, anyone can generate a wallet address under certain conditions. In this example, the condition is that the wallet address begins and ends with the same letters and numbers as the addresses of the targeted victims' wallets, and this address is called Vanity Address. Third, the attacker exploits the transferFrom() function to carry out a transaction worth 0 to or from the victims' wallets. This function calls another function called transfer(), which is responsible for performing transfers, but the most important thing it does is record the transaction in the wallet’s transaction log. The attacker begins monitoring addresses to wait for them to transfer before carrying out the attack, or he attacks randomly. Example: In this transaction, the victim transferred the first 10 USDC from his wallet to an address starting with 0x74C and ending with 0E1cA as a test to ensure that there were no problems before making the larger transfer. Two minutes later, the attacker carried out his attack by exploiting the transferFrom() function to make transfers of 0 from the victim’s wallet. To poison the transfer history and put his fake wallet address similar to the correct address to which the victim transferred 10 USDC. You can see the difference between the middle of the original address and the fake one. The result? The victim verified the last address he transferred to (the fake address) by checking only the beginning and end of the address, and then transferred more than $2 million to the attacker’s wallet address due to this simple mistake. Despite the naivety of the mistake; Most crypto users make the same mistake, and verify the transfer addresses by checking only the first and last characters. Of course, the attacker immediately transferred the funds to UniSwap to launder them and to avoid any possibility of his wallet address being frozen by Circle. Currently, there are millions of addresses on the Ethereum blockchain and the BNB blockchain that It has been targeted by this type of attack, and this number is constantly increasing, so I advise you to be very careful of these attacks. You can follow statistics on attacks via Zero Transfer Phishing. What you can learn from: 1- Always check the entire address before transferring, and not just the beginning and end of the address. 2- Do not transfer large amounts in one transaction. 3- If you find transfers worth 0$ sent from your wallet, do not worry, the wallet has not been hacked.

What are cheap digital currencies in 2024? It is important to understand what cheap cryptocurrencies mean because this term is often misunderstood. Many inexperienced people think that digital currencies that are cheap are those whose price is less than a dollar or a cent, for example. Therefore, many people think that a currency like Shiba, for example, is one of the cheapest and best investments. This is because the coin is much, much cheaper than even 1 cent. But unfortunately this is not what is meant by cheap digital currency. What is meant here is the market value. What is meant by market value is the volume of currencies offered in the markets multiplied by their price, and here the final result is the market capitalization. It is this market capitalization that actually shows whether a cryptocurrency is cheap or not. Therefore, we conclude from this that the Shiba currency is not cheap at all. The market value of the currency is currently about $5.3 billion, and this is a huge number. Therefore, if you expect a 100% increase in this currency, this means an increase in the market value by 5.3$ billion dollars, and this is a very huge amount. Therefore, a project like Dubbz currency, for example, is considered one of the projects with cheap currencies. Although the Dubbz coin is currently worth approximately 3.3$ and is therefore much more expensive than the Sheba. But the market value of this project is estimated at about $33 million. This means that if the market value of this project increases by only 100 million during the bull market, which is a realistic number and occurs frequently, the price of the currency will double about 4 times or much more. This is the most important secret you should know about digital currencies. How do cheap digital currencies increase insanely in 2024? Based on the above, we conclude that cheap digital currencies increase when their market value doubles. Therefore, if we want to search for projects whose currency price is doubling like crazy, we will find that they are those whose market value increases. This means that we should focus on the market value more than the currency price. So, if a project whose market value is one million dollars increases by $10 million, this means an increase of 1000% over the original amount invested. This is because the market value has increased 10 times. However, if a project with a market value of $100 million increases by the same value, the result here is a price increase estimated at 10%. However, if a project worth $1 billion increases by the same value, the effect will be only 1% on the price. Your understanding of this point is very necessary so that you can anticipate the possible price increases that may occur in the next bull cycle. The most important recommendations for cheap digital currencies in 2024. We will now talk about the most important cheap digital currency projects that we expect to rise like crazy during the year 2024. So let’s find out more.#DubbzCurrency Project The Dubbz Currency Project is considered one of the most important digital currency projects on the scene currently. This is due to the strong performance of the project development team. This team knows very well what must be done for the project to succeed. In addition to this, the project is now looking for investors after the project reached about 33$ million dollars in market value. This is very important. Most projects look for investors first and then produce the product. This project did the opposite, and this reflects the strength and solidity of the product presented. The product in this project is a gaming platform that is competed against by players. Each player bets on his victory in the competition and the winner receives the money. The project aims to create a strong community of gamers who love to compete. The project also targets both blockchain games on the one hand and traditional games such as FIFA and Call of Duty on the other hand. The project also allows users to deposit funds on the platform either via cash or crypto. Thus, it targets a large category of players. We expect the project’s market value to break the billion-dollar barrier in the emerging market, which means an increase of more than 30-fold in approximately the coming period.#HERACoin Project We have previously talked about the Hera Coin Project more than once. This project is very important because of the artificial intelligence component involved in it. The project aims to design a decentralized platform on the blockchain of the Aggregator category. This type of platform compares prices across all existing liquidity pools in order to give you the best price to buy the currency you want to buy. Therefore, it is considered a combined platform for all decentralized platforms on the scene. What distinguishes the project is that the team seeks to use artificial intelligence technology to help search for the best price for the currency you want to buy. In addition, this project seeks to be cross-network, meaning that it can work on all different blockchain networks and not just on Ethereum, for example. If the project team succeeds in achieving what it aims to achieve, the value of the project will undoubtedly increase significantly. Currently, the market value of the project is at approximately $30 million. We expect this project to break at least the $500 million barrier in the bull market. Therefore, this is an increase of approximately more than 16 times.#RVFCoin Project # We always talk about the RVF Coin Project. This is a decentralized platform that is also similar to the Hera platform and is considered a competitor to it. It aims to provide a decentralized platform through which digital currencies can be purchased directly either through decentralized platforms or centralized platforms. Thus, it facilitates the ease of trading via decentralized platforms for the user. The platform is characterized by speed, and so far it seems that its prices are much better than the 1Inch platform, its largest competitor, and the Hera platform. But until now, the Hera platform is still being built and developed. So it is not finished yet. But so far it seems that the Rocketx platform is dominating this field. Therefore, we believe that its RVF currency will increase sharply in the coming period, at least 10-fold, and this may make it reach approximately half a billion dollars in market value.
