Phishing remains one of the main causes of crypto asset losses, even among experienced users. In the context of the rapid development of digital finance, attackers are constantly improving social engineering* techniques, website spoofing, and malware distribution. Understanding the mechanics of phishing and the basic principles of protection can significantly reduce the risk of losing funds.
* Social engineering – a set of psychological manipulation techniques used by attackers to obtain confidential information or induce victims to perform specific actions. Social engineering is based on manipulating emotions — fear, trust, urgency, and authority.
According to analysts at CertiK, phishing attacks in 2025 became the most widespread threat in the crypto industry, with more than 250 incidents recorded and total losses of approximately $726 million. These figures confirm that phishing is a systemic problem.
What is phishing?
Phishing is a type of fraud in which attackers create fake versions of official cryptocurrency platforms to obtain users’ confidential data. This refers to information that provides access to digital assets.
The term “phishing” derives from the words “password” and “fishing,” symbolizing the “catching” of sensitive information.
The most common forms of phishing:
- fake websites and mobile applications that copy the interface of well-known exchanges and wallets;
- malware distributed through private messages or email;
- phishing browser extensions;
- fraudulent Telegram bots offering participation in airdrops* and giveaways.
* Airdrop – a mechanism for distributing a project’s tokens to users free of charge, usually for marketing purposes, audience acquisition, or decentralization of asset ownership. To receive an airdrop, users may need to meet certain conditions (e.g., registration, subscription, or interaction with the protocol).
How does phishing work?
To effectively counter phishing threats, it is important to understand how they are carried out.
Phishing usually targets users of specific services — crypto exchanges, wallets, and DeFi platforms. The main goal of the attacker is to gain access to:
- private keys and seed phrases*;
- account logins and passwords;
- one-time two-factor authentication* codes.
* Seed phrase (mnemonic recovery phrase) – a secret sequence of 12–24 words generated by a crypto wallet during its creation and intended to restore access to funds. The seed phrase is mathematically linked to private keys and allows full control over assets to be restored on any compatible device. Sharing a seed phrase with third parties is equivalent to transferring all funds.
* Two-factor authentication (2FA) – an enhanced account protection method requiring two independent elements of identity verification: a primary factor (password) and an additional factor (one-time code, hardware key, biometrics). Even if a password is compromised, the presence of a second factor significantly reduces the likelihood of unauthorized access.
Phishing distribution channels:
- emails;
- private and unmoderated group chats;
- QR codes are placed in public spaces.
A typical phishing scheme:
- The user receives an alarming message about a “problem” with their account or wallet.
- They are urged to follow a link or install an application immediately.
- The fake resource requests login credentials.
- After entering them, attackers gain full control over the funds.
The mechanics are simple but effective, driven by psychological pressure and urgency.
How to recognize phishing and protect assets?
Never share confidential data
Passwords, private keys, and seed phrases must never be shared with third parties under any circumstances.
Scammers often impersonate customer support representatives of crypto services. However, legitimate company representatives do not request such information in private messages.
In messengers such as Telegram, it is useful to check the account creation date and profile change history. A recently created account is a serious red flag.
To protect exchange accounts, it is recommended to use:
- two-factor authentication (2FA);
- anti-phishing codes*.
* Anti-phishing code – a personalized code or phrase set by the user in their account settings on a crypto exchange or service. This code is automatically included in official emails from the platform and allows users to distinguish genuine messages from fake ones. The absence of the correct anti-phishing code is a sign of a possible phishing attack.
2. Emotional control
Phishing actively exploits psychological triggers: fear, urgency, threat of asset loss.
Typical phrases: “Urgently confirm your data or your assets will be frozen.” “Immediately create a backup of your wallet.”
The main goal of phishing is to force the user to act quickly without critical analysis. The only correct reaction is to pause and verify the information.
3. Verify the sender and message content
If an email or message raises suspicion, you should:
- Check the sender’s domain (it must match the official website);
- Make sure the account is marked as official;
- Remember that crypto service administrators do not initiate private conversations.
For additional verification of emails and websites, antivirus solutions such as Norton and Bitdefender can be used.
4. Verify the authenticity of websites and applications
Official crypto exchange and wallet websites usually appear at the top of search results. However, clicking on advertisements may be risky.
Pay special attention to the URL. Replacing a single letter in a domain or adding a hyphen is a common trick.
Useful measures:
- Save official crypto service links in bookmarks.
- Download crypto applications only from the App Store and Google Play;
- Install programs via links from official websites.
To check suspicious resources, phishing site databases such as PhishFort and Database Against Phishing can be used. Modern browsers (Firefox, Opera, Brave) also include built-in phishing protection.
5. Use specialized protection tools
Some crypto wallets and browsers have built-in mechanisms to warn about phishing. For example, MetaMask notifies users when attempting to visit a suspicious website.
The Rabby wallet allows analysis of approvals* — permissions granted to smart contracts when signing transactions.
* Approval (token approval) – a blockchain transaction in which a wallet owner grants a smart contract permission to manage a certain amount of their tokens. Approval is required to interact with DeFi protocols and decentralized exchanges. Attackers can exploit excessive or unlimited approvals to withdraw funds if the contract turns out to be malicious or compromised.
Additionally, you can:
- Check smart contracts via Etherscan.
- Use RugDoc and Honeypot databases;
- Install security plugins: NetCraft, Avast Online Security, McAfee WebAdvisor.
Combining multiple phishing protection tools significantly increases the security level of a user’s crypto assets.
