10 common social engineering attacks and how to prevent them

Many cybercriminals rely more on psychological manipulation than technical know-how to bypass security measures. These social engineers target some of the most primal emotions, like fear and greed, to put people in vulnerable positions and steal from them.

As the crypto market grows in value, digital assets are increasingly tempting targets for social engineering attacks. The total crypto lost to scams and other fraudulent activity hit a record $14 billion in 2025, thanks largely to the rise of AI-powered technologies.

Although crypto scam activity is concerning, there are ways investors can protect their holdings. Let’s talk about what social engineering looks like and how to safeguard against common attacks.

What’s social engineering?

Social engineering is a set of psychological tactics fraudsters use to coax people into revealing confidential information or compromising security systems. Social engineering exploits human behaviors directly, rather than focusing on software or hardware vulnerabilities.

In the crypto space, these malicious actors often trick users into surrendering private keys or login credentials. The hackers then use that information to steal funds from crypto wallets and exchange accounts.

Social engineering attacks vary in complexity, but they usually rely on two key elements: deception and impersonation. For instance, attackers might send emails that appear to come from trusted platforms like Ledger or Trezor.

By borrowing these brands’ credibility, the messages generate a sense of urgency, warning victims that their accounts are at risk or urging them to claim limited-time crypto airdrops. This pressure often leads users to unwittingly compromise their security.

Why are crypto users prime targets for social engineering?

Digital assets are very attractive to scammers, because these assets offer high-value rewards with fewer security barriers than in traditional finance. Crypto can be vulnerable to attacks due to:

• Irreversible transactions: Once you send a digital asset on a peer-to-peer blockchain, there’s no way to freeze or dispute it. The finality of these transfers also means hackers won’t have to deal with chargebacks.
• Personal responsibility: When you download a self-custodial wallet, you’re in full control of sensitive data, such as your private keys and seed phrase. Although this offers autonomy, it also means there’s more risk for human error and little or no support from a third-party authority.
• Lack of centralized recovery: A lack of centralized intermediaries also means you can’t usually rely on backup solutions like customer service or insurance. If you lose crypto through a wallet drainer scam, those funds are often gone for good.
• Pseudonymous nature: Many crypto wallets aren’t tied to real-world identities, and they don’t require users to send in know-your-customer details for verification. This anonymity gives hackers extra cover to evade capture.

What are the common social engineering tactics?

Crypto scams tend to have a few common features, such as:

• Requests for seed phrases or private keys: Either of these details gives an attacker complete control over the victim’s crypto account.
• Pressure to act immediately: Scammers know you’re more likely to send data if they can create a genuine sense of panic or excitement.
• Unsolicited support outreach: Attackers may pretend to be members of a company’s customer support team or community moderators.
• Links that mimic real domains: Many social engineering attacks include URLs leading to websites that look like legitimate business, but collect the login credentials you enter.
• Requests to sign transactions you don’t understand: Scammers may claim that you need to verify your wallet address to complete a transaction or sign a message.
• Deals or airdrops that require upfront approvals: Although it’s common practice to approve smart contracts before accepting an exclusive crypto offer like an airdrop, these programs could contain malicious code that lets fraudsters steal your funds.

10 crypto social engineering attacks

Bad actors never stop refining their social engineering tactics and incorporating the latest technologies, like AI deepfake scams, into their schemes. However, these 10 attacks are common staples of the social engineering playbook.

1. Phishing attacks

Phishing is among the most common social engineering tactics. Hackers send deceptive emails that appear to come from trusted sources, such as cryptocurrency exchanges or decentralized finance (DeFi) platforms.

These messages often create a sense of urgency, instructing recipients to verify their account details to secure their wallets or claim compelling offers. Despite their legitimate appearance, the embedded URLs lead to fake sites designed to steal login credentials or private keys.

2. Vishing

The goals and general strategy behind vishing are the same as for traditional phishing, but the former uses voice calls and messages rather than emails. Fraudsters claim to work with legitimate crypto authorities via phone, then pressure victims into revealing sensitive data.

3. Smishing

Another offshoot of phishing, smishing uses SMS to communicate with victims. Scammers send messages that seem to be from trusted sources and include malicious links or phone numbers. Once again, this tactic relies on prompting fear or urgency to trick victims into providing sensitive information.

4. Spearphishing

Spearphishing uses the same fundamental tactics as phishing, but it focuses on specific individuals to make the scam more personalized and convincing. Rather than sending mass emails, a spearphisher thoroughly researches each target and customizes messages based on that person's background or recent Web3 activities.

These tailored details create a greater sense of credibility, making it more likely that the victim will follow through. When this type of scam targets high-profile figures in the crypto world, such as CEOs or lead developers, it’s called a whaling attack.

5. Water holes

Just like how animals reliably return to a familiar watering hole, most people repeatedly visit the same websites. A water hole attack exploits this knowledge by identifying victims’ most frequently visited sites and embedding malicious code within those pages. Once a target accesses the compromised site, malware infects their device and grants attackers unauthorized access to private data.

6. Tailgating

Sometimes called piggybacking, tailgating is a strategy where attackers gain unauthorized access to a restricted area by physically following someone with legitimate access. For example, a tailgater might wait near the entrance of a cryptocurrency exchange's office and slip in behind an employee. Once inside, that hacker could breach secure systems and install malware on internal networks.

7. Baiting

Rather than using fear to extract personal information, baiting schemes entice victims with attractive rewards. For example, in fake airdrop scams fraudsters promise free tokens that are actually bait to help them steal information. Baiting can also involve more deceptive methods, such as distributing infected cold storage wallets under the guise of providing free cryptocurrency.

8. Quid pro quo

In quid pro quo attacks, social engineers promise something of value in exchange for sensitive information, in order to make their requests appear more credible. For instance, scammers might impersonate representatives from a crypto exchange, then offer technical support in return for a user’s private key or login credentials. Once users comply, attackers use that data to steal digital assets.

9. Pretexting

In a pretexting attack, scammers focus on building trust before asking for sensitive information. They impersonate someone familiar to the victim, such as a friend or colleague, creating a false sense of security. Once they've established trust, the scammers make a seemingly innocent request for personal details, like passwords or account information, under the guise of needing help or wanting to complete a routine task.

10. Impersonation

Impersonation scams are social engineering tactics where attackers disguise themselves as trusted individuals or entities – both online and in person. By assuming a false identity, the attacker aims to appear trustworthy, making it easier to deceive people into sharing confidential information.

How can you prevent social engineering attacks?

Here are some of the best ways to protect yourself against these scams:

• Know what data is off limits: Reputable crypto exchanges, DeFi protocols, and wallets should never ask you for sensitive information like private keys or login credentials. If a message asks for these details, even one from a seemingly credible source, it’s almost always a scam.
• Use antivirus software: Strong antivirus programs can identify and block malware and phishing attempts, by stopping users from unintentionally downloading malicious files and visiting harmful sites.
• Set up two-factor authentication (2FA): Even if an attacker learns your password, they can’t access your account without the second authentication factor, such as a one-time code from an app or through an SMS message.
• Double-check unusual requests: If you receive a suspicious message, resist the urge to react immediately. Inspect the sender’s email address or domain name carefully, and cross-reference any details with information from official websites.
• Be cautious with public Wi-Fi: Avoid accessing crypto wallets or making transactions over public networks, and use a VPN for added privacy when working with sensitive information.
• Update passwords regularly: Make sure all your passwords are long and unique, then change them often.
