✦ Key Insight

Phishing is the delivery mechanism behind most drainer attacks, and it targets attention rather than technology — a hardware wallet does not save you if you approve the transaction.

✕ Common Misconceptions

Reaching sites via search ads or direct messages. Bookmark official domains and use those only. Read what you are signing — an approval request when you expected a swap is the warning.

Detailed Explanation

Crypto phishing usually copies a real exchange, wallet or protocol interface. The goal is either your login details or a signature that grants an attacker access to your tokens. Modern versions look identical to the real thing, down to the domain being one character different.

In Practice

“A search for a decentralised exchange returns a sponsored result one letter off the real domain. The site loads perfectly and asks to connect a wallet.”
