Computers that are physically connected to the edge (so-called “interrupted gaps”) are not completely protected from transmitting data using proprietary intelligence.. OpenAI's researchers have discovered that modern processors can be used to create low-cost, yet efficient, communication channels.
How does it work?
Please note, “Air Gap” transfers externally from the computer connection any gaps, both shotgun and gunless, to ensure maximum security. This is standard practice for protecting critically important systems from external input and flow of data. However, as new research shows, such security approaches may be bypassed.
OpenAI researcher Noam Brown calls out the underestimation of the capabilities of modern AI. He explains that two separate, physically isolated computers can exchange information based on the thermal imaging of the central processing unit (CPU) and its embedded temperature sensors.. This method allows you to create a channel of received communication with extremely low throughput, which operates on the principle of “Morse code”.
The essence of the method is immediate: one computer (the directory) pushes the connection to its CPU, which leads to its heating. Another computer (otrimuvach), installed in order to monitor changes in the temperature of an excessively warm medium or the temperature of a humid environment with the help of installed sensors. The controller can control the heating process by changing its rhythm, and interprets temperature fluctuations as coded messages.
Today's possession and yogo's displeasure.
Current processors (CPUs), graphics processors (GPUs) and motherboards are equipped with numerical temperature sensors. Their main purpose is the cooling system: automatically increasing fan speed when overheating, reducing the processor clock frequency or activating protection against overheating. However, these sensors can also be used for other purposes, as OpenAI research shows..
“People should never underestimate the power of the world,” says Brown. Although this method of received communication has a very low throughput (theoretically, less than a few bits per year), it is still sufficient for transmitting critical information, such as encryption keys or commands for.
Potential inheritances and paths for protection.
It’s cool that to create such a “fusion” between computers, you don’t need a security program installed on your computer. It is enough to have physical proximity and visibility of the sensors. This opens up new vectors for potential attacks, especially in environments with high security risks.
Experts say that although this method is still at the stage of academic research, it demonstrates how difficult threats to security can be in the era of advanced piece intelligence. Primary protection methods, such as physical isolation, may be insufficient against such innovative data transmission methods..
Further research in this area will be aimed at developing methods to detect and counter such attacks. This can include monitoring thermal indicators of systems, installing additional screen-sensitive materials, or introducing specific software features to identify unusual sensor activity.
