CHAPTER 2 

 "DATA BREACHE"

Once upon a time, there was a farmer who had a large field filled with precious crops. The farmer worked hard to tend to his crops and protect them from outside threats.

One day, while the farmer was away from his field, a group of thieves snuck in and stole some of the crops.

The farmer returned to his field to find that his precious crops had been tampered with and some had even been taken away. He was devastated and couldn't understand how this had happened. He had put so much effort into protecting his crops, but somehow the thieves had managed to breach his defenses.

In a similar way, a data breach occurs when a malicious party gains unauthorized access to sensitive information stored in a system or database. Just like the farmer, companies, and organizations work hard to protect their valuable data from outside threats, but sometimes those efforts are not enough to prevent a breach. The consequences of a data breach can be severe, including financial losses, damage to reputation, and even legal action.

Just as the farmer learned from his experience and strengthened his security measures to protect his crops, organizations can also learn from data breaches and take steps to improve their cybersecurity practices and prevent future breaches.

Important Data Breaches in the history

1. eBay Data Breach

The eBay data breach serves as a real-life example highlighting the importance of information and network security in the corporate network.

 eBay, a globally popular online auction platform, suffered a significant data breach in 2014, resulting in the loss of sensitive information of approximately 145 million customers.

The compromised information included customers' names, encrypted passwords, email addresses, postal addresses, contact numbers, and date of birth. 

Storing this kind of information in plain text is not advisable, and it should be encrypted to avoid such incidents.

The compromised information included customers' names, encrypted passwords, email addresses, postal addresses, contact numbers, and date of birth. 

Storing this kind of information in plain text is not advisable, and it should be encrypted to avoid such incidents. eBay stated that no security numbers or credit card information were compromised, but identity and password theft could still pose a severe risk.

eBay claimed that its database containing financial and other sensitive information is stored separately and encrypted. The data breach was caused by hackers compromising a small number of employees' credentials through phishing between February and March 2014. 

It is unclear whether specific employees were targeted to gain access to eBay's network, or if the entire eBay network was monitored and then compromised. eBay reported detecting the cyber attack within two weeks.

2. Equifax Data Breach

In 2017, Equifax, one of the largest credit reporting agencies in the United States, experienced a massive data breach that compromised the personal information of approximately 147 million individuals.

The breach was caused by a vulnerability in the company's website software, which allowed hackers to gain access to sensitive data, including names, social security numbers, birth dates, addresses, and driver's license numbers.

The breach led to a public outcry and a congressional investigation, and Equifax faced a number of lawsuits and fines.

3. The Home Depot Data Breach

Theft of payment card information, such as credit cards, has become increasingly common in recent years. One such incident occurred in 2014 when the Point of Sale Systems of Home Depot was compromised, resulting in a breach of their systems.

In a statement released on September 8th, 2014, Home Depot confirmed the breach, which occurred after the attacker gained access to the login credentials of third-party vendors, allowing them to access the POS networks. 

The hackers exploited a Zero-Day Vulnerability, which created a loophole that enabled them to enter Home Depot's corporate network. Once inside, they established a network connection from their system to Home Depot's network.

The hackers exploited a Zero-Day Vulnerability, which created a loophole that enabled them to enter Home Depot's corporate network. Once inside, they established a network connection from their system to Home Depot's network.

Subsequently, Memory Scraping Malware was deployed to attack the Point of Sale terminals. This malware is highly capable, and it collected millions of payment card information as soon as it was swiped.

Home Depot has taken several remedial measures to address the attack, including the implementation of EMV Chip-&-Pin payment cards. These payment cards have a security chip embedded into them, offering superior protection compared to the old magstripe cards.
