Phishing– Phishing refers to the hackers’ method in which they impersonate a company name or a trustworthy person to get information about some personal data. Hackers usually use this method by sending official and formal-looking codes, emails, and messages. When the target person clicks on this link or email, the hackers get access to your phone.
