How can malware propagate through USB devices?
Malware can propagate through USB devices by taking advantage of the autorun feature on some operating systems. When a USB device is connected to a vulnerable system, the autorun feature automatically executes any program or script found on the device. By placing a malicious program or script on the USB device, malware can exploit this feature to infect the system. To protect against this, it is recommended to disable the autorun feature and regularly scan USB devices for malware.
Malware can propagate through USB devices by infecting the firmware of the USB controller. This allows the malware to run automatically whenever the USB device is connected to any computer. The malware can then spread to the connected system and any other USB devices connected to it. This method is highly effective and difficult to detect or remove. It is advisable not to share USB devices between different systems to prevent malware propagation.
