Cyber Security Examples

Imagine you’re a gatekeeper of a vast city – its walls, filled with precious treasure, stand tall against threats. But the enemies don’t attack with swords and shields; they use cunning, deception, and invisible threats. This city is not made of bricks and stone, but data and digital networks. Your job, as a cyber security professional, is to guard it.


Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from digital attacks, damage, or unauthorized access.

Example 1 – The Sony Pictures Hack (2014): In one of the most high-profile cases, Sony Pictures was targeted by a group calling themselves the “Guardians of Peace.” They leaked unreleased films, sensitive internal data, including employee data and executive emails. This attack not only caused financial losses but also severely damaged Sony’s reputation.

Example 2 – The WannaCry Ransomware Attack (2017): This was a global cyberattack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in Bitcoin cryptocurrency. The attack affected more than 200,000 computers across 150 countries, causing billions in damages, including to the UK’s National Health Service.

Example 3 – SolarWinds Hack (2020): A massive breach of US government systems was discovered, involving complex supply chain attacks. Russian hackers compromised the popular IT management software by SolarWinds, used by many federal agencies and Fortune 500 companies. This allowed them access to sensitive data, highlighting vulnerabilities even in systems believed to be secure.

Cyber Security Examples In-Depth

The Sony Pictures Hack (2014)

In the vivid, bustling world of Hollywood, you might assume that drama unfolds primarily on the silver screen. However, in 2014, a real-life thriller played out behind the scenes at Sony Pictures, showcasing a narrative that was stranger and more intense than any movie.

Picture a modern-day office with computers humming, keyboards clicking, and screens filled with endless streams of data. These are the lifelines of a company. Now, imagine walking into work one day, switching on your computer, and being greeted not by your usual desktop, but by a sinister red skeleton, a symbol of a hacker group calling themselves the “Guardians of Peace.” This was the chilling reality for Sony Pictures employees in November 2014.

The “Guardians of Peace” didn’t stop at intimidating visuals. Much like a torrential downpour sweeping through a city, they flooded the internet with a deluge of stolen data. The information ranged from unreleased films and scripts to sensitive internal data, like employee records and personal emails of executives. Imagine having your private conversations, sensitive business strategies, and valuable intellectual property splayed out for the world to see, like laundry hanging in the breeze. The damage was immense, both financially and reputation-wise.

In essence, the fortress that was Sony Pictures had been breached, not by a catapult or a battering ram, but by the invisible and potent forces of cyber threats. It was a stark reminder that in our modern era, walls and guards are not enough to protect valuable assets; companies need to build and maintain robust cyber defenses.

While it’s impossible to prevent every potential cyber threat, the Sony Pictures hack highlighted the importance of preparing for and mitigating such risks. It’s about continuously testing and updating one’s security system, training staff to recognize threats, and having a swift, effective response plan in place for when things go wrong.

The Sony Pictures hack served as a wake-up call not just for Hollywood, but for businesses everywhere. It was an ominous reminder that even in the glitz and glamour of movie studios, cyber threats are very real and can have far-reaching consequences. It underscored the critical role that cybersecurity plays in our digital age, reminding us that the guard at the city gates must always be vigilant, always be ready, and always be one step ahead of potential threats.

As we continue to rely more on digital platforms and services, the lessons from the Sony hack remain as pertinent today as they were in 2014. We are all participants in this vast digital landscape, and we each have a role to play in ensuring its security. For companies like Sony, the stakes are high, and the audience isn’t just watching a drama unfold on screen – they’re watching how companies protect their assets, their employees, and their customers in an increasingly digital world.

The WannaCry Ransomware Attack (2017)

In a modern-day digital world, imagine a villain that doesn’t need a mask or a getaway car but operates from the shadows, using code as their weapon. This isn’t a work of fiction but a very real, very chilling episode that unfolded in May 2017, known as the WannaCry ransomware attack.

Think about your computer as a personal diary, a space where you store your most valued information, and now imagine that one day, you find it locked. You can see it, but you can’t access it. On the screen, there’s a digital ransom note, demanding payment in an untraceable online currency known as Bitcoin. Your files have been taken hostage, and the clock is ticking to pay up or lose them forever. This was the grim reality for over 200,000 computers in 150 countries during the WannaCry attack.

But WannaCry didn’t just target individuals or businesses; it hit essential infrastructure. One of the most affected was the United Kingdom’s National Health Service (NHS). Medical equipment, such as MRI scanners and blood-storage refrigerators, became unresponsive. Operations were canceled, patient records became inaccessible, and lives were at risk. The cybercriminals didn’t discriminate; they targeted any vulnerable system they could find.

The attack’s weapon of choice was ransomware, a type of malicious software that encrypts a victim’s files. The attackers then demand a ransom from the victim to restore access to the data upon payment. In this case, the ransomware was WannaCry, and it exploited a security flaw in Microsoft Windows, spreading like a highly contagious virus across networks, causing a pandemic of digital proportions.

This event was a stark reminder that digital hygiene, like its health-related counterpart, is crucial. Just as washing hands can prevent the spread of a disease, keeping computer systems updated and patched can ward off many cyber threats.

The WannaCry attack left in its wake a valuable lesson: Cyber security isn’t just about protecting our digital life; it’s about safeguarding our physical world as well. In a society increasingly reliant on technology, a computer virus can potentially halt critical services we depend on daily.

The story of WannaCry underscores the importance of having robust and regularly updated cyber defenses. It’s about recognizing that in the digital world, we are all interconnected, and a threat to one is a threat to all. It’s about understanding that while technology can greatly enhance our lives, it also requires us to be vigilant custodians of our digital landscape.

Today, as we remember the events of the WannaCry attack, we can see it as a turning point, a moment that challenged us to take cyber security more seriously than ever before. The world didn’t just watch this event unfold; it learned, it adapted, and it recognized the ever-evolving landscape of cyber threats.

SolarWinds Hack (2020)

Imagine a world-class magician performing a trick so smoothly that even the most attentive members of the audience fail to see how it’s done. This is what occurred in the digital realm during the SolarWinds hack of 2020. But instead of pulling rabbits out of hats, the tricksters infiltrated some of the most secure systems worldwide, causing chaos, confusion, and raising significant cybersecurity concerns.

SolarWinds, a renowned software firm, created a product that’s akin to a Swiss army knife for network management. Their product, Orion, is used widely by businesses and government agencies to monitor and manage their IT networks.
