Introduction

Phishing is a common cyber attack method that involves forging legitimate emails, social media messages, or websites to trick users into clicking on links or providing personal information in order to steal sensitive information. In the field of cryptocurrency, phishing attacks are also increasing day by day, posing serious risks of property damage and personal privacy leakage to users. This article will discuss the definition of phishing, phishing attack methods in the cryptocurrency field, and preventive measures to improve the security awareness of the majority of users.

The definition and harm of phishing

The word phishing is derived from the word "fishing", which means that fishers lure fish to take the bait by disguising themselves as bait. In the online world, phishers steal sensitive information by forging legitimate emails, social media messages, or websites to trick users into clicking on links or providing personal information.

Phishing attacks have the following characteristics:

Disguise: Phishing attackers usually pretend to be legitimate institutions or individuals, such as banks, e-commerce platforms, social media platforms, etc., to gain the trust of users.

Social engineering: Phishing attackers will take advantage of human weaknesses, such as curiosity, greed, fear, etc., to induce users to click on links or provide personal information.

Highly targeted: Phishing attackers will target specific targets, such as users of a cryptocurrency exchange, users of a certain social media platform, etc.
The harm of phishing attacks is mainly reflected in the following aspects:

Property damage: Phishing attackers steal users’ cryptocurrency assets by stealing their cryptocurrency wallet addresses, private keys and other information.

Personal privacy leakage: Phishing attackers steal users' personal information, such as names, ID numbers, bank card numbers, etc., to conduct illegal activities such as online fraud, identity theft, etc.

Damage to corporate reputation: Phishing attackers cause damage to the credibility of companies or organizations by forging their official websites, emails, etc.

Phishing Attacks in Cryptocurrency

With the cryptocurrency market booming, phishing attackers have also set their sights on this area. The following are common phishing attacks in the cryptocurrency space:

Phishing websites: Attackers create fake websites that are highly similar to real cryptocurrency exchanges, wallet services, or related websites to trick users into entering their login credentials and private keys to steal funds. These fake websites usually use domain names and interface designs that are similar to real websites, making it difficult for users to distinguish the genuine ones from the fake ones.

Phishing emails: Attackers send emails disguised as official communications to induce recipients to click on links or open attachments. These links and attachments may install malware or direct users to phishing websites. Attackers often spoof the sender's email address to make it look like it's from an official agency or cryptocurrency exchange.

Social media phishing: Attackers create fake accounts or publish bait content on social media platforms to attract victims to click on malicious links or participate in fraudulent activities. They may pretend to be cryptocurrency experts, celebrities, or official accounts of cryptocurrency projects to gain the trust of users.

Recently, phishers have focused on platforms such as Slack, Discord and Telegram for the same purpose, using methods such as chat spoofing, impersonating others, and pretending to be legitimate services to conduct phishing attacks.

Advertising: Paid advertising is another tactic used in phishing. These (fake) ads use "registered domain names" and pay to have them pushed into search results. These sites may even be popular search results for legitimate companies or services such as Binance. They are often used as a means of phishing to obtain sensitive information, which may include login details for your trading account.

Malware: Malware spread through phishing attacks, such as Trojans, can lurk on users’ devices and steal cryptocurrency wallets’ private keys and other sensitive information. This malware may be delivered via phishing emails, social media links, or malicious websites.

SMS and phishing (Smishing): Attackers send phishing links via SMS to induce users to click and enter personal information. These text messages may be disguised as official notifications from cryptocurrency exchanges or related institutions, asking users to verify their accounts or update their personal information.

Voice phishing (Vishing): Attackers conduct fraud through phone calls and induce users to provide sensitive information, such as passwords, verification codes, etc. They may pretend to be customer service staff at a cryptocurrency exchange or bank staff to gain the trust of users.

Phishing Prevention Measures in the Cryptocurrency Sphere

To prevent phishing attacks in the cryptocurrency space, users and related businesses should take the following measures:

Improve security awareness: Users should strengthen their awareness of network security, be wary of phishing attacks, not easily click on links from unknown sources, and not easily trust investment advice from strangers.

Don’t share your private keys: Never give the private keys to your Bitcoin wallet to others, and be vigilant about whether any cryptocurrency products and sellers you give them to are legitimate.

Verify the authenticity of websites and applications: When users visit cryptocurrency exchanges and download cryptocurrency wallet applications, they should verify the authenticity of websites and applications and avoid visiting fake websites and applications.

Use complex passwords: Users should use complex passwords when setting passwords for cryptocurrency exchanges, wallets, etc., and change passwords regularly.

Enable two-step verification: When logging into accounts such as cryptocurrency exchanges and wallets, users should enable two-step verification functions, such as SMS verification codes, Google Authenticator, etc., to improve account security.

Check the URL: Move your mouse over the link without clicking and check if the link starts with HTTPS instead of HTTP. But please note that simply checking the beginning does not guarantee that the website is reliable. Check the URL carefully for spelling errors, special characters, and other unusual features.

Update software regularly: Users should regularly update software such as operating systems, browsers, cryptocurrency wallets, etc. to fix security vulnerabilities.

Try another method: If you think you have received a legitimate request to confirm account information for a familiar business, try doing it in a different way and do not click on the link in the email.

Conclusion

In order to effectively deal with this threat, users and related enterprises need to increase security awareness, strengthen vigilance against phishing attacks, and take a series of effective preventive measures. First of all, users should be cautious about emails, text messages and social media messages from unknown sources, and do not trust unfamiliar links or provide personal information.
