Phishing: This is a type of social engineering attack where hackers send emails or text messages that appear to be from a legitimate source. These emails or text messages often contain links that, when clicked, will take the victim to a fake website that looks like the real website. Once the victim enters their personal information on the fake website, the hackers can steal it.
Malware: This is software that is designed to harm a computer system. Malware can be spread through a variety of ways, including email attachments, malicious websites, and drive-by downloads. Once malware is installed on a computer system, it can steal data, damage files, or even take control of the system.
Scams: There are many different types of scams that target crypto users. Some common scams include:
Rug pulls: This is a type of scam where developers create a new cryptocurrency and then sell it to investors. However, the developers then abandon the project and take the money for themselves.
Pump and dump schemes: This is a type of scam where promoters artificially inflate the price of a cryptocurrency in order to sell it at a higher price.
Fake exchanges: This is a type of scam where criminals create fake cryptocurrency exchanges. These exchanges often look like legitimate exchanges, but they are actually just fronts for stealing people's money.
Exchange hacks: Cryptocurrency exchanges are often targeted by hackers. If an exchange is hacked, the hackers can steal the users' funds.
Key management vulnerabilities: In crypto, users own their own private keys, which are used to access their accounts and assets. If a user's private key is compromised, then the hacker can steal the user's funds or assets. It is important for users to store their private keys securely and to never share them with anyone.
Web3 is a relatively new technology, and as such, it is still vulnerable to a number of cyber security threats. Some of the most common cyber security threats in Web3 include:

Smart contract vulnerabilities: Smart contracts are self-executing contracts that are stored on a blockchain. These contracts are used to automate transactions and agreements. However, smart contracts can be vulnerable to vulnerabilities that can be exploited by hackers. For example, a hacker could exploit a vulnerability in a smart contract to steal funds or change the terms of the contract.
