Defining Cyber Security Threats and Risks

Cybersecurity threats and risks refer to potential dangers associated with digital technology, particularly the unauthorized access or damage to information. Cyber threats can originate from many sources, including cyber criminals, hackers, insider threats, nation-states, and even disgruntled employees.

For instance, Ransomware is a type of malicious software that encrypts a victim's files, where the attacker then demands a ransom from the victim to restore access to the data upon payment. A real-life example is the 2017 WannaCry ransomware attack, which affected hundreds of thousands of computers across 150 countries, causing billions of dollars in damages.

Identifying Major Cyber Breaches and their Impact on Businesses and Public Organizations

🔒 Data breaches are instances of unauthorized access to or disclosure of confidential information, often involving sensitive personal or financial data. Companies of all sizes, across all industries, can become victims of data breaches, affecting their reputation and customer trust.

A famous case is the Equifax breach in 2017, where personal data of approximately 147 million people was exposed. This breach had a significant impact on Equifax's reputation and led to the company spending nearly $1.4 billion on cleanup and recovery efforts.

Exploring Common Methods of Cyber Attacks

Common methods of cyber attacks include:

• Phishing: This is the fraudulent practice of sending emails appearing to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers. For example, in 2011, cybercriminals used phishing emails to breach the secured network of RSA Security, a leading cybersecurity company.

• Malware: This refers to any software intentionally designed to cause damage to a computer, server, client, or computer network. A classic example is the Stuxnet malware that was used in 2010 to cause significant damage to Iran's nuclear program.

• DDoS: This stands for Distributed Denial-of-Service attack, a malicious attempt to disrupt the normal functioning of a network, service, or website by overwhelming the target or its surrounding infrastructure with a flood of internet traffic. In 2018, GitHub fell victim to the largest-ever DDoS attack that peaked at 1.35 terabits per second.

Understanding the Motivations behind Cyber Attacks

Cyber attackers are motivated by a variety of reasons. Some are driven by financial gain, like cyber criminals who steal credit card information or conduct ransomware attacks. Others are stimulated by political motives, attempting to disrupt or influence elections, or cause chaos and fear. Then, there are those who hack out of malicious intent or just for the thrill of breaking into secured networks.

One stark example of politically motivated cyberattacks is the 2014 breach of Sony Pictures. The US government attributed the attack to North Korea, which was allegedly motivated by the studio's film, "The Interview," a comedy about a plot to assassinate North Korea's leader.

Examining Real-life Case Studies of Significant Cyber Breaches

Much can be learned from examining past cyber breaches. A key example is the Target data breach in 2013, where personal information, including credit/debit card details of about 40 million customers, was stolen. The breach was traced back to network credentials stolen from a third-party vendor, demonstrating the need for robust third-party risk management.

Another significant case is the Yahoo data breach in 2014, initially reported as affecting 500 million users. However, in 2017, Yahoo revised the estimate to three billion accounts, making it one of the largest breaches in history. This case underscores the importance of timely and accurate communication in the aftermath of a breach.
