Theft of data by the noise from the hard drive
Researchers in the field of security strange new way through which hackers stole doing on their PC users’ data.
Was published a research paper on the Cornell University Library site describes the possibility of hackers stealing data from a computer ‘s hard drive by listening to the sounds issued.This mechanical movement and made different noises, and these sounds are of the kind that is usually heard when the user turn on the computer device.
These voices, in the event that the pirates have installed the correct type of malicious software, transfer data to a nearby device such as a smart phone is outfitted to listen to these voices.
The researchers pointed out that there are some restrictions and limitations to the way DiskFiltration, so that should be listening and recording device resides in the vicinity of no more than 1.8 meters from the primary device.
Data transfer rate as of approximately 180 bits per minute at best, making it impractical way when there are large amounts of data, this method can be used, for example, to record the complicated encryption in less than 30 minutes key.
Can those voices that transmit information without the knowledge of users, and that this method does not require that the computer be connected to the Internet.
And it called the new way of penetration as the “disk nomination” DiskFiltration, and works by controlling the hard disk drive, an arm that moves back and forth across the cylinders when reading and writing data.Viewing:-118
