This is what some of the world’s largest banks of malware look like stacked as hard drives

AI-summarised brief · reviewed before publication

Malware research group vx-underground has an archive of about 30 terabytes of malware data, while VirusTotal has approximately 31 petabytes of malware samples. These enormous datasets are crucial for training detection models and understanding how attacks evolve. To visualize the data, rough calculations were made using 1 terabyte capacity internal hard drives, which are 1 inch in height. Vx-underground's data could fill 30 hard drives, reaching 2.5 feet tall, while VirusTotal's data would fill 31,744 hard drives, reaching about 2,645 feet. This is comparable to the height of the Burj Khalifa or two and a half Eiffel Towers.

💡 Why It Matters

  • · The massive scale of these malware datasets underscores the complexity of cybersecurity threats.
  • · VirusTotal's collection, in particular, represents a vast repository of attack intelligence that can inform threat detection and prevention strategies.
