Mitigation:

• Use a VPN (Virtual Private Network): A VPN encrypts your internet traffic, protecting it from eavesdropping, even on unsecured networks.
• Enable HTTPS: Ensure that the websites you visit use HTTPS. Look for the padlock icon in the address bar.
• Avoid Sensitive Transactions: Refrain from conducting sensitive transactions, such as online banking or shopping, on public Wi-Fi.
• Use Mobile Data: If possible, use your mobile data plan instead of public Wi-Fi.

2. Phishing Attacks: Baiting the Hook

Phishing attacks are deceptive attempts to trick you into revealing sensitive information, such as usernames, passwords, and credit card details. These attacks typically come in the form of emails, text messages, or phone calls that appear to be from legitimate sources.

• Deceptive Emails: Phishing emails often mimic legitimate emails from banks, social media companies, or online retailers. They may contain urgent requests for information or links to fake websites that look identical to the real thing.
• Spear Phishing: A more targeted form of phishing that focuses on specific individuals or organizations. Attackers gather information about their targets to craft highly personalized and convincing phishing messages.
• Whaling: Phishing attacks targeted at high-profile individuals, such as CEOs or other executives.

Mitigation:

• Be Suspicious of Unexpected Emails: Be wary of emails that you were not expecting, especially those that ask for sensitive information or contain links to unfamiliar websites.
• Verify Sender Identity: Check the sender's email address carefully. Look for misspellings or unusual domain names.
• Hover Over Links: Before clicking on a link, hover your mouse over it to see where it leads. If the URL looks suspicious, do not click on it.
• Never Share Sensitive Information via Email: Legitimate organizations will never ask you to provide sensitive information, such as your password or credit card number, via email.
• Report Phishing Attempts: Report phishing attempts to the organization that is being impersonated and to the relevant authorities.

3. Weak Passwords: The Welcome Mat for Hackers

Using weak or easily guessable passwords is like leaving your front door unlocked. Hackers can use various techniques, such as brute-force attacks and dictionary attacks, to crack weak passwords in a matter of seconds.
