๐ What is Phishing? A Comprehensive Guide
Phishing is a type of online fraud where scammers attempt to trick you into revealing personal information, such as usernames, passwords, credit card details, and other sensitive data. They often masquerade as trustworthy entities, like banks, government agencies, or well-known companies, to deceive their victims. These attacks can occur through email, text messages, phone calls, or even social media.
๐ A Brief History of Phishing
The term 'phishing' emerged in the mid-1990s, reportedly among hackers who used email to 'fish' for passwords and financial information. The earliest documented phishing attacks targeted America Online (AOL) users, with scammers posing as AOL employees to obtain user credentials. Over time, phishing techniques have become increasingly sophisticated, adapting to new technologies and preying on human psychology.
