Most of you reading this article probably already know that most devices connected to the Internet are not secure. Each computerς, οποιοσδήποτε server, every device can be hacked and reconfigured for maliciouspurposes, often without the knowledge of the owner. That's how it is USB stick are no exception. 
Some time ago we had published that security researchers discovered a way to rewrite the USB sticks firmware, making them malicious for their owners. This vulnerability is not detected by any security software.
According to Wired, the researchers decided to act. Right now the hack that rewrites the firmware of one USB stick, κυκλοφορεί ελεύθερα στο Internet. The code was leaked directly by security researchers who believe that by publishing the information they will force companies to fix the vulnerability.
High-level services such as the NSA may already have access to this code and thus be able to exploit the vulnerability. However, now that everyone knows hack, companies are forced to take action.
But what can be done with a hacked USB stick? Is that so serious?
By plugging a "tampered" USB stick into a PC, fraudsters can copy all your keystrokes, hide malware on your computer, or perform injections that could spread malware to other USB devices.
As we mentioned above, infected USB devices are virtually undetectable and can not be repaired with a format.
