World’s Largest Malware Banks Visualized as Hard Drives
Have you ever wondered what the world’s largest malware collections would look like if they were stacked as physical hard drives? The answer is surprisingly visual—and it involves some of the most iconic landmarks on Earth.
Recently, the malware research group vx-underground, which claims to host the largest archive of malware source code, revealed its dataset totals about 30 terabytes. For context, that is enough data to fill dozens of standard hard drives. However, a reply from Bernardo Quintero, the founder of VirusTotal, an online malware scanning service, put things into perspective: VirusTotal holds around 31 petabytes of malware samples submitted by users over the years. (One petabyte is roughly 1,000 times larger than a terabyte.)
These staggering numbers raise a fun question: What would these enormous malware collections hard drives look like if you stacked them? To find out, we did some simple math.
How We Calculated the Height of Malware Collections
To keep things simple, we assumed each hard drive is a standard 3.5-inch internal drive with a height of exactly 1 inch. These drives typically offer 1 terabyte of storage capacity, though real-world usable space is slightly less. Using this baseline, we calculated the total number of drives needed for each collection.
For vx-underground’s 30 terabytes, you would need exactly 30 hard drives. Stacked vertically, they would reach just 30 inches—or about 2.5 feet. That is roughly the height of a small child or a stack of three shoeboxes. For perspective, this reporter stands at 6 feet tall, meaning the vx-underground stack would only reach their waist.
Meanwhile, VirusTotal’s 31 petabytes would require 31,744 hard drives. Stacked one on top of another, this tower would soar to about 2,645 feet. That is an impressive height, but how does it compare to real-world structures?
Comparing Malware Data Stacks to Famous Landmarks
The world’s tallest building, the Burj Khalifa in Dubai, stands at 2,722 feet. VirusTotal’s stack of hard drives would fall short by just 77 feet—roughly the height of a seven-story building. In other words, the malware collection is almost as tall as the tallest structure ever built by humans.
Another famous comparison: the Eiffel Tower in Paris measures 1,083 feet. That means VirusTotal’s dataset is about two and a half Eiffel Towers high. Stacking three of these landmarks would barely surpass the malware archive’s height.
This visual exercise highlights the sheer scale of modern cybersecurity data. For researchers, these repositories are not just curiosities—they are essential tools for training detection models and tracking the evolution of digital threats.
Why These Malware Collections Matter
Cybersecurity companies, AI researchers, and threat intelligence firms rely on these massive datasets to develop better defenses. By analyzing millions of malware samples, they can identify patterns, predict new attack vectors, and create more robust antivirus software. Without such collections, the fight against cybercrime would be significantly harder.
As data volumes continue to grow, the physical representation of these archives becomes even more striking. What once fit on a few floppy disks now towers over skyscrapers. This trend shows no signs of slowing down, as malware becomes more sophisticated and widespread.

In conclusion, the world’s largest malware collections, when visualized as hard drives, offer a tangible sense of their enormity. From a modest 2.5-foot stack to a nearly 2,650-foot tower, these datasets represent the front line in cybersecurity research. Next time you upload a file to VirusTotal, remember: you are contributing to a pile of data that could rival the Eiffel Tower in height.
