USB FLASH DRIVES
Small USB flash drives (aka pen drives, aka USB sticks) can be surprisingly dangerous, both their software and their hardware.
Most defensive issues involve their software and this has a very simple solution: any new USB flash drive, whether purchased at retail or found lying on the floor, should be plugged in to a Chromebook running in Guest Mode. If the drive has malicious software, it should not infect the Chromebook (most malware targets Windows or macOS), and if it does infect something, exiting Guest Mode should wipe out the infection.
Better still, format the drive from the Chromebook to hopefully wipe out any possibly hidden software or files.
On the hardware side, the articles below show that a USB flash drive can both explode (when a person is the target of bad guys) or destroy the computer it connects with.
The first I had heard about exploding USB flash drives was in March 2023 as detailed in the articles below. As soon as the flash drive got power from the USB port in a computer, it exploded.
The defense here is a USB extension cord, preferably 6 feet or longer. Plug the cord into the flash drive and then stand far away from the flash drive when you plug the other end of the extension cord into a computer. Maybe even have a barrier between the flash drive and yourself. This is yet another reason to use a Chromebook for USB flash drives as they are, generally, cheaper than other computers. Then too, the below.
Other than avoiding anything but a brand new flash drive, the defense here, yet again, is a Chromebook. This time a very cheap one to serve as the sacrificial lamb, so to speak.
