Common Types of Internet Scams

1. Phishing Attacks
   • Description: Phishing involves fraudulent attempts to obtain sensitive information such as usernames, passwords, and credit card details by disguising as a trustworthy entity in electronic communications.

2. Malware and Ransomware
   • Description: Malware refers to malicious software designed to harm or exploit any programmable device or network. Ransomware is a type of malware that encrypts a victim’s data, demanding payment for the decryption key.
   • Example: Downloading an infected attachment that installs ransomware, locking access to your files until a ransom is paid.
3. Social Engineering
   • Description: Social engineering manipulates individuals into divulging confidential information. This can be done through various means, such as impersonation, pretexting, or baiting.
   • Example: A caller pretending to be from tech support, convincing you to grant remote access to your computer.
4. Online Shopping Scams

   • Example: Stealing your Social Security number to open credit accounts in your name.

How Hackers Operate

Hackers employ a variety of techniques to breach security systems and gain unauthorized access to data:

• Exploiting Software Vulnerabilities: Identifying and taking advantage of weaknesses in software to infiltrate systems.
• Brute Force Attacks: Attempting to guess passwords through trial and error until the correct one is found.
• Man-in-the-Middle Attacks: Intercepting and altering communication between two parties without their knowledge.
• Zero-Day Exploits: Utilizing unknown vulnerabilities in software before the developers have a chance to address them.

Precautions to Protect Yourself

1. Use Strong, Unique Passwords
   • Create complex passwords that combine letters, numbers, and special characters.
   • Avoid using the same password across multiple accounts.
   • Consider using a reputable password manager to keep track of your credentials securely.
2. Enable Two-Factor Authentication (2FA)
   • Add an extra layer of security by requiring a second form of verification, such as a text message or authentication app, in addition to your password.
3. Stay Vigilant Against Phishing Attempts
   • Be cautious of unsolicited emails, messages, or calls asking for personal information.
   • Verify the sender’s legitimacy by checking email addresses and contacting the organization directly if unsure.
4. Keep Software Updated
   • Regularly update your operating system, browsers, and applications to patch security vulnerabilities.
   • Enable automatic updates where possible to ensure you receive the latest security enhancements.
5. Use Reliable Security Software
   • Install and maintain reputable antivirus and anti-malware programs to detect and prevent malicious activities.
   • Enable firewalls to block unauthorized access to your network.
6. Secure Your Wi-Fi Network
   • Use strong encryption (such as WPA3) for your wireless network.
   • Change default router passwords and disable remote management features if not needed.
7. Be Cautious with Public Wi-Fi
   • Avoid accessing sensitive information or conducting financial transactions over unsecured public Wi-Fi networks.
   • Use a Virtual Private Network (VPN) to encrypt your internet connection when using public hotspots.
8. Regularly Monitor Your Accounts
   • Keep an eye on your bank statements, credit reports, and online accounts for any suspicious activity.
   • Report any unauthorized transactions or changes immediately to the relevant institutions.
9. Educate Yourself and Others
   • Stay informed about the latest cyber threats and best practices for online security.
   • Share this knowledge with friends and family to help protect them from potential scams.
