Crypto Phishing Attack

Phishing is by far the most successful attack vector against crypto users because it exploits human psychology rather than technical vulnerabilities. No amount of blockchain security protects you if you voluntarily hand over your seed phrase to a fake support agent. In 2023, crypto phishing stole over $300 million from retail users according to Scam Sniffer — and that's just the tracked, reported subset. The actual total is far higher.

Common phishing vectors in crypto: (1) Fake support DMs on Discord/Twitter/Telegram — 'Your wallet has been flagged, verify here.' Legitimate protocols NEVER send unsolicited DMs requesting credentials. (2) Google/Bing ads for 'MetaMask', 'Uniswap', 'Coinbase' that lead to pixel-perfect fake sites — always bookmark real sites and never click search result ads. (3) Email spoofing mimicking Coinbase, Binance, or Ledger password reset requests. (4) Wallet drainer scripts on malicious NFT claim sites — connecting your wallet to a compromised site can drain all approvals in a single transaction. (5) Fake hardware wallet recovery sites — 'Your Ledger wallet was compromised, enter your seed phrase to restore it.'

Defense requires both technical and behavioral layers. Technical: use a hardware wallet (physical key, immune to browser phishing), enable phishing protection in browsers (MetaMask has built-in warnings), verify smart contract approvals before signing (Revoke.cash for checking existing approvals), use a dedicated browser profile for high-value DeFi. Behavioral: never enter your seed phrase anywhere except during initial physical device setup, treat all unsolicited DMs about your wallet as scams, verify URLs character-by-character before entering credentials (attackers use homograph attacks: 'bìnance.com' with an accented 'i'), and use bookmarks exclusively for financial sites.
