Researchers at Ben-Gurion University in the Negev in the Negev have reached a new attack method called "Glowworm", which benefits from the visual emission from the EDA (LED) of the device, to restore sounds from connected peripherals;This means that he can already spy on electronic conversations.
The researchers said in their published observations that "the glowing worm attack - which is the visual" Tempest "attack - can be used by the sailors to recover the sound by analyzing the optical measurements obtained through an optical electrical sensor directed to the light from the power index of different devices(For example: loudspeakers, USB lights).
The "Timbest" attack is the attack through which mechanical tools and gaps are used in spying or spying, not electronic or software, in which case the tool and vulnerability have a visual nature, so it was called "Timbest visually".
The researchers explained how to attack by "analyzing the power index's response to different sound devices, and it turns out that there is a visual correlation between the sound that is played by the sound amplifiers connected to the device and the severity of its power index, because the power index of different devices is connected directly to the power line and the intensity of the device's power index.Located to energy consumption. "
If the light emitted from these indicators is fluctuating depending on the conversation and the rate of energy consumption that affects the strength and stability of the light, the device can eavesdrop on the conversation easily.
The incandescent worm attack was tested in a variety of experimental situations.The tests revealed that the attacker can eavesdrop on a conversation by tracking the amplifier power index with a good clear distance of 50 feet (15 meters) and clearly from 115 feet (35 meters).
The researchers also revealed that many devices are vulnerable to incandescent worm attack, including Google Home Mini, Google Nest Audio and SRS SRS and others.
But good news is that this attack can be overcome simply by placing a black strip on the light of the device's power index.However, manufacturers may want to think about this attack when designing their new products to ensure that they are safe from the glowing worm attack from the beginning.
