It is typically introduced to the target environment via an infected USB flash drive, thus crossing any air gap. The worm then propagates across the network, scanning for Siemens Step7 software on computers controlling a PLC. In the absence of either criterion, Stuxnet becomes dormant inside the computer.
Removal of stored data: anyone with physical access can erase all of the data held within the USB dead drop (via file deletion or disk formatting), or make it unusable by encrypting the data of the whole drive and hiding the key (see also the related topic of ransomware). Removal of the entire device: thieves can steal the USB drive itself. [15]
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]
There are different models of the device, the latest being USB Killer v4. Earlier generations, including USB Killer v2, were developed by a Russian computer researcher with the alias Dark Purple. [3] [7] Similar homemade devices have been constructed from camera flash parts, [8] both of which already feature high-voltage circuitry.
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
Once the device has been plugged in it can be used to infect an entire network. One example of malware that propagates through removable media such as USB flash drives is Stuxnet, which caused significant damage to Iran's nuclear program. The risk from an attack like this can be reduced by automatically scanning media for malware and ...
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
New flash memory-based media implementations, such as solid-state drives or USB flash drives, can cause data erasure techniques to fail allowing remnant data to be recoverable. [1] Software-based overwriting uses a software application to write a stream of zeros, ones or meaningless pseudorandom data onto all sectors of a hard disk drive.
