How to Reject Hackers: The Ultimate Guide to Handling Bitcoin

There is no doubt that Bitcoin has become a phenomenon that can never be ignored. The number of mainstream businesses adopting this payment method is steadily increasing, and more and more venture capitalists are also testing the waters to invest in various Bitcoin startups. However, as the world's first popular cryptocurrency, the partial anonymity provided by its blockchain technology is so attractive to hackers and scammers.

If you suffer losses due to theft of your credit card or bank account, you can recover your losses through the bank or insurance company. But what if your Bitcoins are stolen? Who will recover your losses? Therefore, it is crucial to protect your PC and Bitcoin wallet.

How hackers target your Bitcoin wallets and exchange accounts:

To maximize the security of your Bitcoin wallet, you first need to understand how hackers target your computer, phone, or server to steal your Bitcoin. Here are the most common attacks that hackers can use to steal your Bitcoin by exploiting vulnerabilities in your operating system:

1. Phishing

"Network IP address phishing" has always been one of the most common, evil attack methods. Sometimes, "IP phishing" will be the first step of a more complex type of attack. In my opinion, if the "target" IP is recorded, the hacker is halfway to success.

In most cases, the hacker will create a malicious link and send it to the target machine, and once the user clicks on it, the IP address of his/her device will be logged.

If you use an online Bitcoin wallet, you may have received a "fake" email that contains a link that directs you to a "fake" wallet login page. After you enter your account information, this information will be sent to the hacker, and then you know... Of course, since all top online wallet providers have SSL保护, if you are careful, you can easily identify these "fakes".

2. Keylogger

In my opinion, keylogging is the easiest way to capture passwords. Keylogging software is so deceptive that even tech geeks can fall for it. In simple terms, a keylogger is a script that, once installed on the target computer's operating system, records all keystrokes and sends them to the hacker, mostly via FTP.

The success of a keylogger depends on many factors, including the operating system, the age of the keylogger, and the level of infection resistance of the target computer. Keyloggers are usually injected through a web browser. The security vulnerabilities of the target machine are determined by the type of browser it uses; the operating system installed on the target machine, whether it is genuine, and whether the operating system has been updated with the latest security vulnerabilities and bug fixes.

3. Stealing Programs

Stealer software retrieves your passwords and login credentials stored on your browser. Once FUD, some stealers can be very powerful. In most cases, a stealer is a .bat file that can be injected into the target machine online or through a USB drive.

4. Cookie hijacking

Cookie hijacking, or session hijacking, is the process of exploiting a valid computer session to maliciously gain unauthorized access to information or services on the target machine.

Since HTTP communication uses multiple TCP connections, a web server must have a way to identify each user's connection. Session tokens and cookies are the most commonly used client authentication methods. Cookie hijacking has many forms, including session monitoring, cross-site scripting attacks, man-in-the-middle attacks, and browser man-in-the-middle attacks.

How can you protect your Bitcoin wallet and exchange account?

1. Operating system and bug fixes

Using a genuine operating system, regularly updating security vulnerabilities and fixing bugs is the first step to protect your Bitcoin wallet. I do not recommend that you use android设备to access your Bitcoin wallet. Because, in my opinion, the Android operating system has many security vulnerabilities, it is like a magnet, attracting hackers.

2. Desktop Bitcoin-qt Vs Online Wallet

The security of most online Bitcoin wallets is questionable. A large number of online wallet providers and Bitcoin exchanges have suffered losses due to various security vulnerabilities. If you must use an online Bitcoin wallet service, please use a two-factor authentication service to increase the security of your account.

Bitcoin-qt can maximize the security of your account and is one of the best options for keeping your private keys. Don't put all your eggs in one basket. You can keep a small amount of money on your computer or smartphone for daily expenses and use "cold storage" to store most of your Bitcoin. No matter which wallet you use, you should use a strong password. Multi-signature is another feature that can maximize the security of your assets.

3. Use a proxy and VPN

Proxy servers and VPNs can increase the security of your Bitcoin wallet. Although most people mistakenly believe that VPNs make them anonymous online, this is not the case. Of course, it does increase your privacy. You can think of VPNs as "curtains" that protect the privacy of your activities inside your house, but the address of your house is still clearly visible.

A VPN reduces the chances of a hacker gaining access to open ports on your router, which means they’re less likely to be successful.

4 Anti-phishing browsing behavior

You should be cautious before clicking on any link. As mentioned before, if you click on a malicious link, your IP address will be recorded by the hacker. Whenever you are suspicious of a link, use the "Website Phishing Check" service before clicking on it.

5. Encrypt and backup your wallet

A wallet backup is essential to protect against losses due to computer failure or human error. Encrypted wallet backups can help you recover your bitcoins if your computer or phone is stolen. You should encrypt your online backups, and any backups that are accessible over the Internet should be encrypted.

6. Cold Storage

Offline wallets are sometimes referred to as "cold storage." Cold storage is the safest way to store Bitcoin, and it is also the storage method you must learn.

in conclusion:

Although Bitcoin represents the most targeted digital currency by hackers, you can resist most attacks by following strict security measures. When conducting Bitcoin transactions, you should do so on a secure computer using a secure browser.
