Phishing attacks have become one of the most prevalent threats on the internet today, compromising sensitive information and personal data of millions of users. In an era where digital transactions and online interactions are commonplace, having a reliable security tool is crucial for safeguarding users against such malicious activities.

What is Phishing?

Phishing is a cybercrime in which attackers impersonate a legitimate organization or individual to trick victims into providing sensitive information, such as usernames, passwords, credit card details, or personal identification numbers. This is often done through deceptive emails, websites, or text messages that appear authentic. Phishing can take various forms, including email phishing, spear phishing (targeted attacks), and vishing (voice phishing). Each method relies on manipulating human psychology to elicit trust and persuade individuals to share confidential information.
