What & Why

What are Cyber Attacks?

A cyber attack is any offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices. These attacks can be launched by individuals, groups, or even state-sponsored actors with various motivations, including financial gain, espionage, political activism, or simply causing disruption. The methods used in cyber attacks are diverse and constantly evolving, making it a persistent challenge for cybersecurity professionals and individuals alike. — Texas A&M Vs.

Types of Cyber Attacks

• Ransomware: This is a type of malware that encrypts a victim's data and demands a ransom payment for its release. Ransomware attacks have become increasingly common and can cripple businesses and organizations.
• Phishing: Phishing attacks use deceptive emails, messages, or websites to trick individuals into revealing sensitive information, such as usernames, passwords, and financial details.
• Malware: Malware, short for malicious software, encompasses various forms of harmful software, including viruses, worms, Trojans, and spyware, designed to damage or disrupt computer systems.
• Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks: These attacks aim to make a website or online service unavailable by overwhelming it with traffic from multiple sources.
• Man-in-the-Middle (MITM) Attacks: In a MITM attack, attackers intercept communications between two parties to steal information or manipulate data.
• SQL Injection Attacks: These attacks exploit vulnerabilities in websites to access or manipulate databases.
• Password Attacks: Techniques such as brute-force attacks and credential stuffing are used to gain unauthorized access to accounts by cracking passwords.
• Insider Threats: These attacks originate from individuals within an organization who have access to sensitive information and systems.

Why Cyber Attacks Matter

• Financial Losses: Cyber attacks can lead to significant financial losses due to ransom payments, recovery costs, legal fees, and lost business.
• Data Breaches: Sensitive information, including personal data, financial records, and intellectual property, can be stolen, leading to identity theft and privacy violations.
• Reputational Damage: A cyber attack can severely damage an organization's reputation and erode customer trust.
• Operational Disruption: Cyber attacks can disrupt business operations, causing downtime, delays, and lost productivity.
• Legal and Regulatory Repercussions: Organizations may face legal penalties and regulatory fines for data breaches and non-compliance with data protection laws.
• National Security Threats: Cyber attacks can target critical infrastructure, such as power grids and communication systems, posing risks to national security.

How-To / Steps / Framework Application

Building a Strong Cybersecurity Posture

1. Password Management:
   • Use strong, unique passwords for all accounts.
   • Utilize a password manager to securely store and manage passwords.
   • Avoid reusing passwords across multiple sites.
2. Multi-Factor Authentication (MFA):
   • Enable MFA on all accounts that support it.
   • Use authenticator apps or hardware security keys for added security.
3. Software Updates:
   • Keep operating systems, software, and applications up-to-date.
   • Install security patches promptly to address known vulnerabilities.
4. Network Security:
   • Use a firewall to protect your network from unauthorized access.
   • Secure your Wi-Fi network with a strong password and encryption.
   • Regularly monitor network traffic for suspicious activity.
5. Data Backup and Recovery:
   • Regularly back up your data to a secure off-site location.
   • Test your backup and recovery process to ensure it works properly.
6. Employee Training:
   • Educate employees about cyber threats and best practices.
   • Conduct regular phishing simulations to test employee awareness.
7. Incident Response Plan:
   • Develop and implement an incident response plan to handle cyber attacks effectively.
   • Define roles and responsibilities for incident response.
   • Regularly test and update the incident response plan.
8. Security Software:
   • Install and maintain up-to-date antivirus and anti-malware software.
   • Use intrusion detection and prevention systems to monitor network traffic for malicious activity.
9. Email Security:
   • Be cautious of suspicious emails and attachments.
   • Avoid clicking links or downloading attachments from unknown senders.
   • Use email filtering to block malicious emails.
10. Physical Security:
    • Secure physical access to computers and servers.
    • Protect devices from theft or loss.

Examples & Use Cases

Real-World Cyber Attack Scenarios

• Ransomware Attack on a Hospital: A hospital's computer systems are infected with ransomware, encrypting patient records and disrupting critical services. The attackers demand a ransom payment to decrypt the data, forcing the hospital to decide between paying the ransom or risking patient safety.
• Phishing Attack on a Bank: Cybercriminals send phishing emails to bank customers, impersonating the bank and requesting sensitive information, such as account numbers and passwords. Customers who fall victim to the phishing scam have their accounts compromised, resulting in financial losses.
• DDoS Attack on an E-commerce Website: An e-commerce website is targeted by a DDoS attack, overwhelming its servers with traffic and making the website unavailable to customers. This results in lost sales and reputational damage.
