Sonic virus: Stealing data from headphones microphone as usual

[Guide] headphones, microphones, sound cards and other audio equipment, will also be leaked confidential information channels. Sonic virus: Steal data from headphone microphone as usual attack bi Chinese language station March 6 reported in the traditional era, if a network of computers infected with the virus, the unit's IT administrator must say "unplug the network cable", because the network cable is the physical channel of the virus transmission. However, researchers in the United States have found that new computer viruses can be transmitted and attacked through sound waves, even if the computer is not networked, the same will be attacked, in addition, headphones, microphones, sound cards and other audio devices, will also be leaked confidential information channels. This new type of virus, no need for solid channels, they are in the way of high-frequency sound waves in the air, no matter where a computer in a physical network, as long as close enough, can be "virus sound" coverage, will be infected. Recently, some network security researchers have begun to show the concept of sonic viruses, which can leak information through sound peripherals such as microphones and sound cards, said Engin-kirda, a co-founder of LastLine, a professor at Northeastern University. The mechanism of the virus is not difficult to understand, the virus code will be converted into high-frequency sound waves, through and other computer's sound card and audio peripherals to "interact" to achieve transmission, for this virus, whether the target is connected to the network cable, in the unit which LAN, is not important. To understand how the virus travels in sound waves, the professor said, think about how the modem works-how the computer communicates digitally through a traditional telephone line that transmits audio. For the Sonic virus, the security industry does not seem to have a good solution. But leaking information from a computer through sound waves is no longer a news story. Before the advent of modern computers, some researchers found that a combination of sound from a dot-matrix printer could be used to reverse engineer and "decipher" the printed text. Thankfully, though, the virus is likely to spread and attack in sound waves, but the threat is not as severe as the traditional virus. The researchers at Northeastern University also say hackers must have the ability to use sound waves to carry out attacks. (Dawn compiles)
