Imagine this scenario.
You are at an airport, waiting for your flight, when you then notice a USB drive on the ground near the seating area. Curiosity might get the best of you, and you pick the USB up, believing that someone may have left it behind. While you may look around to see who may have dropped it, there is no one around that seems to be looking for it. While your flight is still a while away, you plug in the USB thinking it might have information pertaining to the owner so you can return it. As soon as you plug it in, your computer freezes, and alarming messages appear on the screen. It becomes evident that the USB contains a malicious virus that is in the process of exploiting your device.
Malware-infected USBs are becoming a growing problem.
There have been increasing issues of malicious actors infecting USBs and dropping them somewhere for a user to pick up. While one might assume that refraining from connecting unknown USB drives is an obvious precaution, it is still alarmingly common.
USB Security Facts:
In 2017, Kaspersky Lab conducted a data study that revealed a concerning statistic:
Studies have emphasized the risks as well as the lack of precaution in using unsecured USB drives. For instance, in a notable experiment, nearly 300 unmarked USB flash drives were intentionally left around a college campus. Surprisingly, more than 50% of the discovered USB drives were plugged into computers by unsuspecting students and teachers, exposing their devices to potential IT threats.
- Approximately one in four USB users worldwide fell victim to a 'local' cyber incident each year.
- An infected flash drive plugged into an unprotected device could instantly infect and spread the virus through any network it’s attached to.
- One of the highest-profile hacks with a malicious USB occurred in Iran, where the attempt infected the entire company's nuclear facility with malware.

Given the potential severity of these consequences, it is crucial to exercise caution when encountering unknown USB drives. Also, refrain from connecting them to your devices.
