7 Easy Strategies to Prevent Hacks and Scams Effectively

In 2025, the threat landscape for cryptocurrency security continues to grow, with over $2.4 billion illicitly stolen in the first half of the year alone — already surpassing the total thefts of 2024. While sophisticated exploits capture headlines, most losses stem from basic scams and user errors, emphasizing the importance of adopting robust security habits. With rising phishing attacks and increasingly sophisticated social engineering tactics, crypto investors of all levels must remain vigilant. Strengthening everyday security measures can significantly reduce the risk of becoming the next target of a malicious actor.

Crypto security remains a significant concern as malicious actors exploit both technological gaps and human vulnerabilities. Recent statistics show that more than 300 incidents have resulted in the loss of billions, with notable breaches, like the Bybit theft linked to North Korean groups, skewing overall figures. Nonetheless, most crypto losses are attributable to straightforward traps such as phishing links, malicious wallet approvals, SIM swaps, and fraudulent support accounts.

Fortunately, everyday safety measures are accessible and simple to implement. These habits can dramatically reduce your risk of falling prey to common crypto scams and hacks.

1. Ditch SMS: Use phishing‑resistant 2FA everywhere

Reliance on SMS‑based two‑factor authentication exposes users to SIM‑swap attacks, a prevalent threat that leads to wallet drainings. More secure options include hardware security keys or platform passkeys that resist phishing attempts. Prioritize securing your email, exchange, and password manager accounts first. Regulatory agencies consistently stress the importance of using multi‑factor authentication that isn’t vulnerable to social engineering.

On top of enabling robust 2FA, store backup codes securely offline, and use withdrawal allowlists to restrict fund movements. Notably, phishing attacks targeting crypto users have surged by 40 % in 2025, often leveraging fake exchange sites to deceive victims.

2. Signing hygiene: Stop drainers and toxic approvals

Most crypto fund losses happen after users unknowingly grant unlimited permissions through malicious signatures. These approvals allow bad actors to drain assets repeatedly without further user interaction. To prevent this, always scrutinize each approval request carefully—particularly for “setApprovalForAll” or “permit” transactions.

If interacting with new decentralized applications (DApps), use a burner wallet for testing to avoid exposing your main assets. Regularly revoke unused approvals via tools like Revoke.cash, reducing window for exploitation. Improved signing discipline can prevent a rise in drainer‑based thefts, especially targeting mobile users.

3. Hot vs. cold: Split your spending from your savings

Think of your crypto wallets like bank accounts: a hot wallet is your daily cash, while a cold wallet acts as a secure vault. Keep most assets offline to avoid malware or phishing risks. For long‑term storage, write your seed phrase on steel or paper — never digital devices or cloud storage.

For larger holdings, multisignature wallets requiring multiple device approvals add an extra barrier against theft. Always test recovery procedures with small amounts to ensure access in emergencies. Remember, in 2024, private key compromises accounted for nearly 44 % of stolen funds.

4. Device and browser hygiene

Maintaining a secure device setup is vital. Keep all software updated, minimize browser extensions, and consider dedicated browsers for crypto activities to minimize attack surfaces. Hardware wallet users should disable blind signing by default to prevent exposure of transaction details. Opt for a minimal environment to prevent malware infections or session hijacking.

5. Verify before you send: Addresses, chains, contracts

Crypto assets are lost most often due to sending funds to incorrect addresses or on wrong networks. Always double‑check recipient addresses, especially during first‑time transactions, and perform small tests when possible. Verify token contracts on official sites or reputable explorers, and never manually type addresses — use copy‑paste and confirm the first and last characters.

6. Social engineering defense: Romance, “tasks,” impersonation

The biggest risks aren’t code‑based but involve deceit and manipulation. Scammers forge relationships or pose as support staff, tricking victims into revealing seed phrases or depositing funds into scam addresses. Remember, legitimate support will never ask for private keys or direct payments through gift cards or Bitcoin ATMs. Recognizing these red flags and maintaining skepticism can stop many social engineering attacks.

7. Recovery readiness: Make mistakes survivable

Despite best practices, slips happen. Prepare a plan: keep an offline “break‑glass” list of recovery resources like support contacts, revocation tools, and regulatory agencies. When incidents occur, act swiftly—transfer remaining assets to new wallets, revoke permissions, and report the breach with detailed transaction data. Proper preparation helps turn a potential catastrophe into a manageable setback.

If the worst happens: What to do next

Immediate action can limit losses: move remaining funds to a secure wallet, revoke permissions, update passwords, and contact your exchange to flag malicious addresses. Filing reports with authorities, including transaction hashes and supporting evidence, can assist investigations. Ultimately, disciplined security habits, vigilant verification, and proactive recovery plans are your best defenses in the evolving landscape of crypto threats.
