Phishing attacks are fraudulent attempts to deceive people into revealing sensitive information or installing malware such as ransomware. These attacks are often delivered via email spam and can trick individuals into giving away sensitive information or login credentials. Phishing attacks can be targeted or untargeted, with common targets including financial institutions, email and cloud productivity providers, and streaming services. Spear phishing is a targeted phishing attack that uses personalized emails to trick a specific individual or organization into believing they are legitimate. Phishing often uses social engineering techniques to trick users into performing actions such as clicking a link or opening an attachment, or revealing sensitive information. Successful phishing attacks can lead to identity theft, credit card fraud, ransomware attacks, data breaches, and huge financial losses for individuals and corporations.
