Common Attacks in The Digital World:
Phishing Attacks
Phishing is a type of cyberattack in which bad actors imitate genuine entities in order to fool people into disclosing sensitive information such as login passwords, personal data, or financial information.
Example of a Phishing Attack
Imagine receiving an email that appears to be from your bank, warning you of suspicious activity on your account. The email includes a link urging you to “verify your account” by clicking on it. However, upon clicking, you are redirected to a fraudulent website that mimics your bank’s login page, and any information you enter is captured by the attacker
