Cyberattacks: Vital lessons from corporate giants


Ciberataques: Lições vitais de gigantes empresariais

Cyberattacks have become an omnipresent threat in today's business world.

Far from being mere inconveniences, they can have devastating repercussions for the affected companies.

In this article, we explore some of the most significant cyberattacks ever recorded and the valuable lessons we can learn from these incidents.


The WannaCry Ransomware Attack (2017): WannaCry was a global ransomware attack that affected over 200,000 computers across 150 countries, including systems of hospitals, businesses, and governments. This attack exploited vulnerabilities in outdated operating systems.


Lesson: The critical need to keep operating systems and software updated. Many victims of WannaCry could have avoided the attack by simply applying a security patch that Microsoft had released months earlier.


The Marriott International Attack (2018): This incident involved unauthorized access to the Starwood reservation database, a subsidiary of Marriott, resulting in the exposure of personal information of up to 500 million guests.


Lesson: The importance of cybersecurity in merger and acquisition management. The security breach originated in Starwood's network before its acquisition by Marriott, highlighting the need for detailed security assessments during the merger and acquisition process.


The Target Corporation Attack (2013): This attack led to the theft of credit and debit card data of about 40 million Target customers. Hackers gained access to this data through the credentials of a third-party vendor.



The importance of ensuring security in the supply chain. This case underscored the need for companies to implement rigorous security measures not only internally but also in their interactions with third parties and vendors.


These examples reinforce the idea that cybersecurity is an integral and indispensable part of modern business strategy. The lessons learned from these attacks underscore the need for constant vigilance, regular security updates, and a holistic approach to protecting data and critical infrastructures.
