• Pretexting: Pretending to be a trustworthy person.
• Baiting: Offering fake rewards, like USB drives with malware.

Examples of Social Engineering Attacks
In 2016, the Democratic National Committee was hacked. Spear-phishing emails tricked staff into giving away their login details.

Ways to prevent ransomware attacks

• Raising Awareness to Prevent Attacks.
• Teach employees about social engineering tactics.
• Always check if requests are real, especially for sensitive information.

Threat 5: Distributed Denial-of-Service (DDoS) Attacks
The fifth type of cyber security threats is DDoS, here is what it means and ways to prevent.

How DDoS Attacks Disrupt Services?
DDoS attacks flood a network or server with too much traffic. This makes the service unreachable. These attacks often aim to extort businesses or create chaos.

Reasons for DDoS Attacks
Attackers can be rival companies, unhappy people, or activists wanting to send a message.

Methods and Tools to Fight DDoS

• Use content delivery networks (CDNs) to help manage traffic.
• Monitor network traffic for any unusual spikes.
• Use firewalls and DDoS protection solutions.

Threat 6: Insider Threats
The sixth type of cyber security threats is Insider Threats, explore what it means and ways to prevent.

The Risks of Insider Threats
Insider threats come from people inside an organization who misuse their access to harm the company. These threats are serious because insiders already have access to sensitive information, making it hard to spot harmful actions.

Types of Insider Threats

• Malicious Insiders: Employees or contractors who share or damage data on purpose for personal gain or revenge.
• Negligent Insiders: Team members who accidentally harm security, like falling for phishing scams or mishandling confidential information. Preventive Measures Against Insider Threats - Access Control: Make sure employees only have access to the information they need for their jobs. - Monitoring and Auditing: Regularly check user activity logs for any suspicious actions. - Training and Awareness: Teach employees about security rules and the importance of protecting sensitive data.

Threat 7: Zero-Day Exploits
The seventh type of cyber security threats is Zero-Day Exploits, explore what it means and ways to prevent.

What Are Zero-Day Vulnerabilities?
A zero-day vulnerability is a flaw in software that the vendor does not know about. It has not been fixed yet. Cybercriminals use these vulnerabilities to attack before they are found or fixed.

The Lifecycle of a Zero-Day Exploit

• Discovery: Attackers find a weakness in software or hardware.
• Exploitation: They use this flaw to break into systems or steal sensitive information.
• Disclosure and Patching: The vendor learns about the problem and starts to work on a fix.

How Organizations Can Tackle Zero-Day Threats?

• Regular Updates: Always update software and operating systems to reduce the risk of known vulnerabilities.
• Threat Intelligence: Use tools to monitor and spot suspicious activities that may indicate a zero-day exploit.
• Layered Security: Use firewalls, intrusion detection systems, and endpoint protection to lessen the impact of these attacks.

Threat 8: Advanced Persistent Threats (APTs)
The eighth type of cyber security threats is APTs, explore what it means and ways to prevent.

Characteristics of APTs
Advanced Persistent Threats (APTs) are long-term attacks. They are often carried out by well-funded groups, like nation-states or organized cybercriminals. These attacks aim to steal sensitive data over time instead of causing immediate harm.

Industries Targeted by APTs
