Security Progress 3/365
Day 1-3: Introduction to Cyber Threats
Overview of common cyber threats.
Real-world examples to set the stage.
Phishing Attacks:
The most well-known attack type is phishing; we will go through the case studies that can take a real-world example.
Types of phishing (email, spear phishing, vishing).
Real-world examples and case studies.
2016 Yahoo Breach
Scenario: Yahoo experienced a massive data breach where attackers used spear phishing to access employee credentials.
Outcome: Personal information from over 500 million accounts was compromised, highlighting the impact of successful phishing attacks on large organizations.
Lesson: Even well-established companies can be vulnerable to phishing attacks, emphasizing the need for robust security measures.
COVID-19 Vaccine Phishing
Scenario: Cybercriminals exploit the global interest in COVID-19 vaccines, sending emails offering fake vaccine appointments or information.
Outcome: Victims may provide personal information or download malicious attachments.
Lesson: Stay informed through official health channels, and be cautious of unsolicited emails related to sensitive topics.
Prevention measures and best practices.
User Education:
Training Programs: Conduct regular cybersecurity awareness training for employees and individuals to recognize phishing attempts.
Simulated Phishing Exercises: Perform simulated phishing exercises to test and reinforce users' ability to identify phishing emails.
Verify Email Sources:
Check Sender's Email Address: Scrutinize the sender's email address carefully, especially in cases where the email is unexpected or urgent.
Use Email Authentication: Implement DMARC (Domain-based Message Authentication, Reporting, and Conformance) to prevent email spoofing.
Use Multi-Factor Authentication (MFA):
Enable MFA wherever possible to add an extra layer of security, even if credentials are compromised.
Keep Software and Systems Updated:
Regularly update operating systems, browsers, and security software to patch vulnerabilities that could be exploited by phishing attacks.
Implement Email Filtering:
Use advanced email security solutions, including anti-phishing filters, to detect and block malicious emails before they reach the inbox.
Malware Infections:
Different types of malware (viruses, worms, Trojans).
Case studies of malware attacks.
How to detect and remove malware.
Ransomware Incidents:
Notable ransomware attacks.
Impact on organizations and individuals.
Strategies for preventing and responding to ransomware.

How these attacks work and their consequences.
Best practices for securing networks.
Insider Threats:
Types of insider threats (accidental and malicious).
Case studies of insider attacks.
Mitigation strategies and monitoring techniques.
Credential Attacks:
Password attacks and their variations.
Real-world examples of compromised credentials.
Multi-factor authentication and password hygiene.
IoT Security Risks:
Vulnerabilities associated with IoT devices.
