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

TL;DR

Researchers have estimated the size of the world’s largest malware datasets, with VirusTotal’s 31 petabytes of data equating to about two and a half Eiffel Towers stacked. This highlights the enormous scale of threat intelligence resources.

Cybersecurity researchers have calculated that the world’s largest malware data repositories, such as VirusTotal’s 31 petabytes, are comparable in height to approximately two and a half Eiffel Towers when stacked as hard drives, emphasizing the enormous scale of threat intelligence collections.

Malware research group vx-underground reports its archive contains about 30 terabytes of malware source code, while VirusTotal, an online malware scanning service, states it has accumulated roughly 31 petabytes of malware samples contributed by users. To visualize this scale, assuming 1-terabyte hard drives, vx-underground’s data would fill about 30 drives, reaching 30 inches tall. In contrast, VirusTotal’s data would occupy around 31,744 drives, stacking up to approximately 2,645 feet, slightly shorter than Dubai’s Burj Khalifa. These comparisons demonstrate the vast volume of malware data collected for cybersecurity and research purposes, highlighting the challenge of managing and analyzing such enormous datasets.

Why It Matters

This massive scale of malware repositories underscores the importance of advanced data analysis, machine learning, and automated detection systems in cybersecurity. The size of these datasets reflects the ongoing arms race between cybercriminals and defenders, with threat intelligence firms relying on extensive data to identify, analyze, and counter evolving attack techniques. Understanding the scale also emphasizes the logistical and technological challenges involved in storing, processing, and securing such vast amounts of sensitive data.

Background

Both vx-underground and VirusTotal are key players in the cybersecurity ecosystem, providing extensive malware samples for research and detection. VirusTotal, launched in 2004, has grown to become a major resource for analyzing files and URLs for malicious content, with user-contributed data reaching into petabytes. vx-underground, a more recent entity, claims the largest collection of malware source code, totaling about 30 terabytes. These repositories are critical for training AI detection models and understanding attack evolution, especially as cyber threats become more sophisticated.

“The comparison of these datasets to towering structures highlights just how enormous and complex modern malware research has become.”

— Zack Whittaker, TechCrunch security editor

“Our platform has accumulated roughly 31 petabytes of malware samples contributed by users over the years.”

— Bernardo Quintero, founder of VirusTotal
