Real Analysis of one of the Most Common Cyber Security Attacks | Case Study

In this article, we will analyse a real case of a cyber security incident and explore the lessons learned from this event. The case study highlights the importance of taking a proactive approach to cyber security and emphasises the need to implement robust measures to protect data and infrastructure.

Case Study: Ransomware Attack

A medium-sized retail company recently experienced a ransomware attack that paralysed its operations and put its sensitive data at risk. The attack began when an employee opened a phishing email disguised as official communication from a vendor. The email contained a malicious attachment that, when opened, initiated the encryption process of the company’s files.
The ransomware quickly spread through the company’s systems, making the data inaccessible and demanding a ransom in cryptocurrency for its release. The company found itself in a delicate situation, facing the prospect of losing valuable data, business disruption, and potential damage to its reputation.

Response and Recovery:

Faced with this critical situation, the company implemented its cyber security incident response plan, which included the following steps:

• Isolation and containment: The company’s cyber security team acted swiftly to isolate the infection, shutting down the compromised systems and preventing the spread of the ransomware.
• Forensic analysis: Forensic cyber security experts were called in to investigate the attack’s origin, identify the exploited vulnerabilities, and collect evidence for future legal actions.
• Communication and notification: The company immediately communicated the incident to stakeholders, including customers, suppliers, and relevant authorities, in compliance with data breach notification regulations.
• Restoration and recovery: The IT team worked tirelessly to restore the affected systems from recent backups and implement additional security measures to prevent future attacks.
