- Adware: Malware that displays unwanted advertisements and tracks your browsing habits.
Phishing
Phishing is a type of social engineering attack that involves sending fraudulent emails, messages, or websites designed to trick you into revealing your personal information. Attackers often impersonate legitimate organizations or individuals to gain your trust.
Example: A phishing email might appear to be from your bank, asking you to update your account information by clicking on a link. The link leads to a fake website that looks identical to your bank's website, where you are prompted to enter your username and password. Once you enter your credentials, the attackers can use them to access your real bank account.
Data Breaches
Data breaches occur when sensitive information is stolen from organizations or companies due to security vulnerabilities or cyberattacks. These breaches can expose your personal information, such as your name, address, credit card number, and social security number.
Example: In 2013, Yahoo suffered a massive data breach that affected over 3 billion users. The breach exposed users' names, email addresses, passwords, and security questions.
Man-in-the-Middle Attacks
Man-in-the-middle (MITM) attacks involve intercepting communication between two parties without their knowledge. Attackers can use MITM attacks to steal sensitive information, such as passwords, credit card numbers, and personal messages.
Example: When using public Wi-Fi at a coffee shop or airport, an attacker could set up a fake Wi-Fi network that looks legitimate. When you connect to the fake network, the attacker can intercept your traffic and steal your personal information.
Social Engineering
Social engineering is a technique that involves manipulating people into revealing confidential information or performing actions that compromise their security. Attackers often exploit human psychology, such as trust, fear, or curiosity, to achieve their goals.
Example: An attacker might call you pretending to be a technical support representative, claiming that your computer has been infected with a virus. They might then ask you to grant them remote access to your computer, which they can use to install malware or steal your personal information.
