It affected multinational companies and caused billions of dollars in damages. Its rapid spread via the EternalBlue vulnerability demonstrated the importance of securing networked systems. More information can be found at CNBC’s NotPetya coverage.

Each of these cases demonstrates different attack vectors such as software vulnerabilities, human error, and supply chain infiltration. Understanding these incidents will help you recognize similar threats and develop preventative measures in your own work.

Time Management Tips for Completing the Test

Efficiently managing your time during the assessment requires preparation and focus. Here’s how to approach it:

• Review the Entire Paper First: Quickly scan all the sections to understand the structure and identify easier questions to tackle first. This will help you allocate time based on difficulty and importance.
• Set Time Limits: Break down the total time into sections based on the number of questions. For example, if there are 50 questions and 2 hours, aim to spend around 2 minutes per question. Adjust as necessary for more complex tasks.
• Prioritize High-Value Questions: Focus on questions that carry more marks or require deeper analysis. If time is running short, leave simpler ones for later.
• Avoid Overthinking: If you’re stuck on a question, move on and return to it later. Spending too long on one issue can waste time that could be better used on other questions.
• Check Your Work: Save the last 10-15 minutes to review your answers. This will help you spot any mistakes or missed details that can boost your score.

Practicing with timed mock tests will help you develop the necessary skills to manage your time effectively under pressure.
