Authored By: Ankita Prajapati

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.


Cybersecurity incidents have become increasingly common in today’s digital age. These incidents can have a significant impact on individuals and organizations, resulting in financial losses, reputational damage, and even legal consequences. In this story, we will discuss some real-life cybersecurity incidents and the lessons learned from them.

The attackers exploited a vulnerability in Equifax’s website to gain access to sensitive data. The incident showed the importance of patching known vulnerabilities promptly and implementing multi-factor authentication.

NotPetya Malware Attack

In 2017, the NotPetya malware attack affected numerous organizations worldwide, including the shipping company Maersk, which reported losses of up to $300 million. 

The attackers used a fake software update to distribute the malware, which caused significant disruption to computer systems. The incident emphasized the importance of implementing a robust incident response plan and regularly backing up critical data.

Twitter Hack

In 2020, several high-profile Twitter accounts, including those of Barack Obama and Elon Musk, were hacked in a bitcoin scam. The attackers gained access to the accounts through social engineering and then used them to promote a bitcoin scam.
