The Dangers of USB Drives: My Recent Experience with Malware

In today’s digital landscape, the convenience of using USB drives for file transfer comes with its own set of risks. Recently, I had a disturbing encounter that raised important questions about the safety of these devices, particularly in shared environments such as schools.

It all started when I connected my USB drive to my personal computer. As I attempted to access the files, I noticed it took longer than usual to load. While waiting, my Windows Defender flagged a potential threat linked to my USB drive. The warning indicated a severe risk, prompting immediate concern.

This wasn’t the first time I faced issues with my USB. Previously, when I plugged it into a school computer to transfer some academic work, I encountered a perplexing problem: all my files became hidden and were altered to a “.lmk” format. It was alarming at first because it seemed like my important documents had vanished. Thankfully, a simple command in the Command Prompt resolved the issue, restoring my files.

However, this recent situation felt different. After having shared my USB with classmates for printing purposes, I couldn’t shake the feeling of unease. Although I trust my friends and believe they wouldn’t intentionally infect my device, I started to consider that the school computers might be susceptible to malware. It’s not uncommon for digital threats to lurk on public machines, potentially transmitted through unsuspecting users.

Upon writing this post, I felt it was crucial to seek advice and share my experience with others. I promptly disconnected my USB Wi-Fi dongle to cut off any internet connection, prioritizing security over convenience.

Key Takeaways for USB Users:

1. Be Cautious with Shared Computers: Always consider the security of machines that aren’t your own.
2. Keep Security Software Updated: Ensure your antivirus is active and regularly updated to detect the latest threats.
3. Regularly Scan External Drives: Before accessing files, perform scans to catch potential malware.
4. Backup Important Files: Always have backups of crucial documents in case of unexpected file loss.

In conclusion, while USB drives are invaluable tools for transferring information, they can also pose significant risks. By remaining vigilant and informed, we can protect our data from potential attacks.
