The best target for hackers: Cryptocurrencies and NFTs

The best target for hackers: Cryptocurrencies and NFTs

 


blockchain development services company created Bitcoin in 2009. It is an online currency with encrypted ledgers. The popularity of digital currency is growing among both individuals and businesses looking for non-traditional investment options. Cryptocurrency is like all technology. It has financial and security risks. This includes the inability to control the system or the anonymity of crypto-users. Continue reading to learn more about the most serious crypto created by blockchain development services company and common cyberattacks used for cybercrime.

 

Wormhole: What's it all about?

A wormhole is a blockchain bridge that blockchain app development companies built between Solana and Ethereum. This web-based app allows users to transfer cryptocurrency and non-fungible tokens among both networks. This crypto bridge is compatible with many blockchain networks such as Avalanche, Binance Smart Chain and Ethereum Oasis. To secure 20 Ethereum (ETH), the Wormhole could transfer Ethereum from Solana to Solana. Smart contracts are digital contracts that are stored on blockchain networks. They can be automatically run when certain conditions are met. These contracts temporarily block cryptocurrency and mint or release tokens requested by the user.

 

Once the contract is established, the user may mint the equivalent amount wrapped in Ethereum via the Solana network. Wrapped tokens can be cryptocurrencies taken from another blockchain or tokens with the same value as the original cryptocurrency. Unlike the original crypto, Wrapped tokens can be used on other blockchain networks created by blockchain app development companies. They can also be redeemed for the original cryptocurrency.


Wormhole Cyberattack

Cybercriminals discovered a flaw in Wormhole's platform, which allowed them to steal $321,000,000 worth of wrapped Ethereum (weth). This enables them to rob 321 million people. Wormhole reported the breach immediately and shut down the platform for further investigation. The Solana blockchain network, developed by blockchain development services, was used to create and steal 120,000 Ethereum tokens. The thieves stole 80,000 WETH tokens and converted them into Ethereum. They then sold the remainder on Solana. This attack was fourth in scale and is the most significant hack of the year.


During the investigation, Wormhole temporarily stopped token transfers to its Blockchain Bridge. Wormhole's 16-hour team worked tirelessly to fix the vulnerability. Jump Crypto, a trading platform, has replaced all stolen ETH. This made sure that no user funds were affected by the exploit. A Wormhole representative sent an email to the hacker offering a $10 million bug bounty and a Whitehat Agreement in exchange for all stolen funds being returned. Whitehat agreements Allow ethical hackers to find security flaws within hardware, software, or networks and receive a specified reward. In the ideal case, you will avoid criminal prosecution.


Common Cyberattacks


It's not surprising that cryptocurrency has security risks if you keep your fingers on the latest tech news. Wormhole and other blockchain bridges developed by blockchain development services are particularly risky due to their complexity. These crypto bridges need to be compatible with multiple chains. This means hackers could find security flaws and steal crypto. Let's look at some of the most prevalent cyberattacks in the crypto market.

 

Compromised Registration Forms

Hackers can steal sensitive information from users through online registration forms. The criminals then can sell the information on the black market.

 

Cryptojacking

Cryptojacking refers to the unauthorized access and use of another person's computer, phone or tablet. The hacker can then mine cryptocurrency developed by best blockchain companies and profit by selling the stolen tokens. This attack is usually carried out by cybercriminals who get the victim to click on an email link that installs crypto mining code. A hacker could also infect a website with malicious JavaScript code that will automatically run when it is loaded in the browser. This code runs in the background, and the user won't know it has stolen their cryptocurrency. Two signs that your device has been compromised are running slower than normal and slowing down.

 

Cryptocurrency Scams


Cybercriminals are skilled at tricking people for money, even crypto. To scam crypto users, hackers use many different tactics:

 

  • To trick people into installing fake software on their OS (operating system) by creating fake Android app Packages (APKs).
  • Fake domains are pretending to be official blockchain platforms developed by best blockchain companies.
  • Phishing ads and social media campaigns can include malicious attachments and links.
  • Spam emails lure people into entering sensitive information or buying or trading tokens on false sites.

 

Hacked Trading Platforms

Cybercriminals use the anonymity, lack of control and flexibility of trading platforms to steal cryptocurrency. Since the creation of the first digital token, dozens of cases have supported this. Apart from the Wormhole attack and PolyNetwork (decentralized finance) project, another prime example is PolyNetwork which was hacked in 2021 and suffered a staggering $600 million loss. Bitmart, a cryptocurrency trading platform, was another example. It was also hacked, and lost almost $200 million from one company account.

 

Phishing

Phishing is a method hackers use to gain unauthorized access to sensitive information such as bank account numbers and Social Security numbers. Hackers create phishing campaigns to target crypto trading platforms. It is designed to trick users into providing their login credentials on a fake website, form or mobile app. These scammers will sell the stolen credentials or keep them for ransom until the victim pays the required funds.

 

Third-Party Applications

Hackers also target third-party applications to steal user data. Cybercriminals can use this sensitive information to launch attacks against blockchain platforms developed by top 10 blockchain development companies. These large-scale attacks can have a devastating effect on crypto users, often millions. These attacks greatly impact many people's lives, as many crypto users invest in crypto for their families' futures, business opportunities, or emergency funds.

 

How to combat cyberattacks using blockchain

Cyber thieves can leverage their skills and resources to profit from a cryptocurrency-loving world. These criminals can use multiple techniques to launch attacks on blockchain platforms, third-party applications, individuals, and organizations. Although some argue that cryptocurrency should be banned because of the lack of regulations and central control defined by top 10 blockchain development companies, like financial institutions, most people believe digital money will continue to exist.

Businesses and individuals need to find ways to counter these cyberattacks. It is crucial to keep up-to-date with security best practices and cyberattacks. 

Companies can better decide which blockchain networks they will use and then implement a layer of security that protects the most important things to them.
