Pen-drives are a serious threat to your computer's health. Most computers in Bhutan are infected by malware (MALicious softWARE, such as viruses, worms, and Trojan horses) when a "sick" pen-drive (also known as a "flash drive" or "USB stick") is inserted into your desktop or laptop. Malware can reduce the performance of your computer, use your bandwidth, and in general be quite annoying. But it can also pose a real threat.
It was recently revealed that in 2008, an infected pen-drive was inserted into a laptop belonging to the US military. Once the laptop was infected, classified documents could be transferred to remote servers operated by a foreign government or other covert organization. The malware also spread and contaminated other computers in the military network. This attack, which started in the Middle East, was described by a U.S. official as the "most significant breach" of the U.S. military's computers ever.
