1. Phishing Attacks

What it is:
Phishing is a form of social engineering where attackers trick users into revealing personal information, such as passwords, bank details, or login credentials, through fake emails or websites.

How to avoid it:

• Always verify the sender’s email address before clicking links.
• Avoid opening attachments from unknown sources.
• Use email filters and anti-phishing tools.
• Look for HTTPS in the website URL before logging in.

2. Ransomware

What it is:
Ransomware is malicious software that encrypts your files and demands payment for their release. Businesses and individuals are frequent targets because data has become a valuable asset.

How to avoid it:

• Back up your files regularly to an external or cloud drive.
• Keep your software and operating system updated.
• Never click suspicious links or download unknown attachments.
• Install reliable antivirus and anti-ransomware software.

3. Data Breaches

What it is:
A data breach occurs when sensitive or confidential data is accessed or exposed without authorization. This often happens through weak passwords, unpatched software, or compromised servers.

How to avoid it:

• Use strong, unique passwords for every account.
• Enable two-factor authentication (2FA).
• Limit personal information shared online.
• Regularly update and audit your security settings.

4. Malware and Spyware

What it is:
Malware includes viruses, worms, and spyware that infiltrate your device, steal information, or disrupt system operations. Spyware, in particular, can monitor user activity without consent.

How to avoid it:

• Install and update antivirus software.
• Avoid downloading free software from unreliable websites.
• Scan USB drives before use.
• Keep your browser extensions to a minimum.

5. Identity Theft

What it is:
Identity theft happens when cybercriminals use your personal information—like your name, Social Security number, or credit card details—to commit fraud or access your accounts.

How to avoid it:

• Shred physical documents containing sensitive information.
• Monitor your financial accounts regularly.
• Use credit monitoring services.
• Avoid oversharing personal information on social media.

6. Insider Threats

What it is:
Not all cyber threats come from outside your organization. Insider threats arise when employees or contractors misuse access to company systems or data—intentionally or by mistake.

How to avoid it:

• Limit access based on roles and responsibilities.
• Train employees on cybersecurity best practices.
• Use access logs and monitoring systems.

7. Weak Passwords

What it is:
Simple or reused passwords are one of the most common causes of cyberattacks. Hackers use automated tools to guess passwords and gain access to accounts.

How to avoid it:

• Use password managers to create and store complex passwords.
• Change passwords every few months.
• Avoid using personal details like birthdays or names.

8. Public Wi-Fi Attacks

What it is:
Public Wi-Fi networks in cafes, airports, and hotels can be unsafe. Hackers often use them to intercept user data through man-in-the-middle attacks.

How to avoid it:

• Avoid logging into sensitive accounts while on public Wi-Fi.
• Use a Virtual Private Network (VPN).
• Disable automatic Wi-Fi connections.
