What is Phishing Attack?
A phishing attack in crypto is a social engineering scam that tricks users into revealing private keys, seed phrases, or signing malicious transactions — the most common attack vector for individual fund loss.
WHY IT MATTERS
Phishing is how most individual crypto losses happen. Techniques include: fake websites that mimic legitimate dApps (Uniswep instead of Uniswap), malicious token approval requests, fake customer support on Discord/Telegram, and airdrop scams that require 'claiming' through a drainer contract.
Wallet drainers are increasingly sophisticated — they present legitimate-looking approval requests that actually grant unlimited token access to the attacker's contract. One wrong signature and all your tokens can be stolen.
Defense: verify URLs manually, never share seed phrases, review all transaction/signing requests carefully, use hardware wallets (verify on device screen), and be skeptical of unsolicited messages.
