The infection started when a USB flash drive containing malicious code created by a foreign intelligence agency was plugged into a laptop that was attached to United States Central Command. From there it spread undetected to other systems, both classified and unclassified. [1] [2]
Storage: USB flash drives are hard to track physically, being stored in bags, backpacks, laptop cases, jackets, trouser pockets or left at unattended workstations. Usage: tracking corporate data stored on personal flash drives is a significant challenge; the drives are small, common and constantly moving.
EPROMs, flash memory and other solid-state drive store data using electrical charges, which can slowly leak away due to imperfect insulation. Modern flash controller chips account for this leak by trying several lower threshold voltages (until ECC passes), prolonging the age of data.
Agent.BTZ, also named Autorun, [1] [2] is a computer worm that infects USB flash drives with spyware. A variant of the SillyFDC worm, [3] it was used in a massive 2008 cyberattack on the US military, infecting 300,000 computers.
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...
This attack works by programming the fake USB flash drive to emulate a keyboard. Once it is plugged into a computer, it is automatically recognized and allowed to interact with the computer. It can then initiate a series of keystrokes which open a command window and issue commands to download malware.

Flash-based solid-state drives can be used to create network appliances from general-purpose personal computer hardware. A write protected flash drive containing the operating system and application software can substitute for larger, less reliable disk drives or CD-ROMs. Appliances built this way can provide an inexpensive alternative to ...
