Phishing is one of the most common ways hackers steal cryptocurrency. Hackers send fake emails, fake messages, or fake links. These look real, but they are not. Their goal is to trick you into giving your login details or private keys.
Hackers create emails and websites that look exactly like real crypto platforms. They may pretend to be an exchange, a wallet app, or customer support. When you click their link, it opens a fake website that steals your information.

- They do not check the website URL.
- They share private keys or recovery phrases.
Always remember: Real companies never ask for your private keys or recovery phrases.
2. Malware and Spyware

Keyloggers record everything you type. Trojans hide in fake apps or files. When installed, they give hackers full access.
