🛡️Complete Crypto Security Guide: Protect Your Assets Like a Professional
Summary
In the crypto world, security is not optional. There is no customer service to recover your funds, no deposit insurance, no transaction reversal. This guide covers everything you need to know to avoid being a victim of the most common attacks.
The 4 most common attack vectors
(1) PHISHING: fake websites mimicking exchanges to steal credentials. Solution: verify exact URL, use bookmarks. (2) MALWARE: malicious software stealing keys or replacing clipboard addresses. Solution: antivirus, verify first/last address letters. (3) SOCIAL ENGINEERING: someone posing as support to get your seed. Solution: distrust ANYONE contacting you first. (4) RUG PULL: project team abandoning with funds. Solution: research team, audits, distribution.
Professional level security setup
A robust setup includes: password manager (Bitwarden, 1Password) with long master password; 2FA with authenticator app (Authy) — NEVER SMS because vulnerable to SIM swapping; email dedicated only to crypto; hardware wallet for main positions; separate hot wallet for DeFi with limited amounts.
SIM Swapping: the attack that empties accounts in minutes
SIM swapping is one of the most sophisticated attacks. The attacker convinces your phone operator to transfer your number to a SIM they control. They receive all your SMS including 2FA codes. In minutes they reset passwords and drain custodial accounts. Michael Terpin lost $24M in 2018. Solution: authenticator app (Authy) instead of SMS, ideally physical security key (YubiKey).
Key takeaways
- The 4 vectors: phishing, malware, social engineering, rug pull
- Use password manager + 2FA with app (never SMS)
- Email dedicated exclusively to crypto
- Hardware wallet for large positions, hot wallet for small DeFi
- SIM swapping empties custodial accounts in minutes — never use SMS 2FA
Warning
No exchange, wallet, or legitimate tech support will ever ask for your seed phrase, password or 2FA codes. If anyone asks for them, it is a theft attempt without exceptions.
