Phishing is a form of fraud which is aimed at gaining access to your account and/or sensitive information.
Phishing usually involves phony emails or direct messages on social networks asking you to visit a link, download a file or open an attachment.
If you take any of these actions, it may result in infecting your device with malicious software that an attacker will use to steal your personal data like login credentials, bank account information, credit card numbers, etc.
You can protect yourself against phishing by carefully reading every message that hits your inbox and refraining from any actions you are asked for if you notice signs of phishing. The first easy step you can take right now to prevent phishing is to use different email addresses for your public contact info and for your store login.
