🎯 Common Attack Vectors

🎣

Phishing

Fake websites/emails impersonating wallets or exchanges to steal your keys.

Example:

"Your wallet needs verification! Click here and enter your seed phrase..."

Defense:

Never click links in emails. Always type URLs manually. Bookmark legit sites.

🦠

Malware

Keyloggers, clipboard hijackers, and screen capture tools that steal keys.

Example:

Software that changes copied addresses to attacker's address

Defense:

Use antivirus. Hardware wallets. Verify addresses. Clean systems for key generation.

🔧

Physical Theft

Stolen devices with wallets or seed phrases stored insecurely.

Example:

Laptop stolen with unencrypted wallet file or seed phrase in notes app

Defense:

Encrypt devices. Use strong passphrases. Store seeds in secure locations.

🎭

Social Engineering

Manipulating people to reveal keys through trust or urgency.

Example:

"I'm from support. To fix your account, I need your seed phrase..."

Defense:

No legitimate service EVER asks for your keys. Trust no one with keys.

✅ Security Checklist

Hardware wallet for holdings > $1000

⚠️

Remember: Not Your Keys, Not Your Coins

If someone else holds your private keys (like an exchange), you don't truly own those coins. They can:

  • Get hacked and lose your funds
  • Go bankrupt (FTX, Mt. Gox, etc.)
  • Freeze your account without warning
  • Require KYC or deny withdrawals

For serious holdings, always withdraw to a wallet where YOU control the private keys.
