In the first half of 2025, over $2.4 billion was stolen in more than 300 crypto incidents, surpassing the total thefts in 2024. Simple traps like phishing links and fake support accounts cause most losses. Implementing strong 2FA, careful signing, and separating hot/cold wallets can significantly reduce risk. Having a recovery plan with revocation tools and support contacts is crucial.
To enhance security, switch to phishing-resistant 2FA and lock down critical logins like email and exchanges. Avoid SMS codes and use hardware security keys. Long, unique passphrases, backup codes, and withdrawal allowlists also help protect funds. Phishing attacks targeting crypto users increased by 40% in the first half of 2025.
Be cautious when signing transactions to prevent wallet drainers from draining funds without permission. Use a burner wallet for risky interactions and revoke unused approvals regularly. Good signing habits can prevent drainer-driven thefts, particularly on mobile devices.
Differentiate between hot wallets for spending and hardware wallets for secure storage. Keep private keys offline and test recovery setups before transferring funds. Multisig wallets add an extra layer of security for larger balances. Private key compromises accounted for 43.8% of all stolen crypto funds in 2024.
Maintain device and browser hygiene by enabling automatic updates and minimizing browser extensions. Use a dedicated browser for crypto activities to prevent leaks. Disable blind signing on hardware wallets and handle sensitive actions on a clean desktop. Updates patch vulnerabilities attackers exploit.
Verify addresses, networks, and contracts before sending crypto to avoid sending it to the wrong place. Make small test payments for new transfers and verify contracts on official sites. Copy and paste wallet addresses to prevent clipboard swaps and avoid copying addresses from transaction history.
Beware of social engineering scams like romance and job schemes that pressure victims into depositing funds or revealing private keys. Real support will never request private keys, send you to lookalike sites, or ask for payment through Bitcoin ATMs or gift cards. Cut off contact immediately if you spot red flags.
Prepare for recovery by keeping a break-glass card with key recovery resources like exchange support links and official reporting portals. Include transaction details in reports to help investigators connect cases. Act fast if you click a malicious link or send funds by mistake. Transfer remaining assets to a new wallet and escalate by contacting exchanges and filing reports with regulators.
Implementing seven key habits can block most everyday crypto threats: strong MFA, careful signing, hot/cold wallet separation, clean devices, verifying before sending, staying alert to social engineering, and having a recovery plan. Start small with upgrades to 2FA and signing hygiene to prevent catastrophic losses in 2025.
