Researchers noticed that AI has its Achilles heel.

The AI is the computer program.  Or a very complex computer program. With multiple layers. That means if somebody attacks the AI server that hosts the large language model, LLM. That makes it possible to steal the AI. Basically, that means the hacker can download the LLM source code into that person's own server. 

Researchers from South Carolina State University. Made an Attack on the AI server. Using electromagnetic waves. That means they didn't make a straight attack against the server. That means the server's firewalls and other things are helpless against the attack. The technology that those people used based the electromagnetic waves.

"Researchers have shown that it’s possible to steal an artificial intelligence (AI) model without directly hacking the device it runs on. This innovative technique requires no prior knowledge of the software or architecture supporting the AI, making it a significant advancement in model extraction methods." (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

“AI models are valuable, we don’t want people to steal them,” says Aydin Aysu, co-author of a paper on the work and an associate professor of electrical and computer engineering at North Carolina State University. “Building a model is expensive and requires significant computing sources. But just as importantly, when a model is leaked, or stolen, the model also becomes more vulnerable to attacks – because third parties can study the model and identify any weaknesses.” (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

So, by using this method. Researchers were able to determine the architecture and specific characteristics – known as layer details – researchers and later hackers, would need to make a copy of the AI model.

When an electromagnetic wave travels through another field affects its strength. That means. Things like radars that send electromagnetic waves through data lines can read data that travels in those lines. The idea is that the system acts like an X-ray system. It sends a radio wave through the data line and the sensor at the opposite side detects changes in that field and it can read data. 

The laser system that makes laser rays scatter can used to steal data from optical networks. Or the system can create a hologram around the laser ray. If the laser ray oscillates that hologram can steal information from those laser rays. 

If somebody can steal the LLM that is a very bad thing. Developing those things is expensive. But there is always some other possibility. Bad boys can use those stolen computer programs to create the evil twin for the use of China, North Korea, and Russia. In the wrong hands, the LLM can create virus codes and control cyber-attacks. 

Normally the ability to make malicious code is denied from legal or official LLMs. But in illegal copies, those abilities can exist. So, hackers can use those LLM evil twins for cyber attacks and industrial espionage. The LLM can also make cyber attacks on surveillance systems.

Light tornadoes. Along with high-speed, high-power radio waves can increase network power.

"By employing quasicrystals, researchers at Aalto University have found a new way to enhance data transmission using light vortices, potentially multiplying the current capacity of optic fibers by 8 to 16 times.

The light tornadoes can increase the speed of the network by 16X. From its present speed. The light tornado is one of the ways how to make faster and probably safer networks. The light-based network would be the tool of the future. The laser-based networks are easier to protect. And they can support things like quantum computers better than modern electric-based networks.

When a light tornado travels inside another laser ray, that prevents the attackers from seeing the message. That is an idea of the quantum network. In quantum networks, the attacker cannot reach information without disturbing the network. If somebody puts a sensor through the laser ray. That thing means that there is a cut in the protecting laser ray. The optical networks are harder to jam than electric or radio wave-based systems. The problem is that the laser ray cannot travel through barriers like walls. 

It's possible. The system shoots laser rays to the sensor, which resends them through the wall using an optical data cable. Inside the house, the system can use radio waves. If the house is at the same time as the Faraday cage that radio impulse cannot travel out from it. The Faraday cage denies the inside radio waves travel out from the house. The radio wave-based relay station can send data because people who are outside the Faraday cage cannot hear the signal.

Magnetar is a neutron star with an extremely powerful magnetic field. The magnetic field stresses the plasma ring around the magnetar. When the energy level in plasma is high enough, that plasma sends radio waves in both directions. About half of that energy goes to space. But half of it travels into the plasma ring. That radio wave impacts a very strong magnetic field. 

That increases its power. The thing is that the energy level in the plasma ring must be higher than in the magnetar so that the radio wave can travel inside it. The impacting radio waves form the standing wave. And then sooner or later. The energy that comes or reflects from the plasma presses the standing wave against the magnetar's spin axle. And it's possible that researchers can copy those conditions to communication systems. 

One way to make the network secure is to use coherent radio waves, or radio masers to communicate. 

The knowledge of the fast radio burst, FRB can make it possible to create extremely accurate high-power radio bursts. The idea is that the system can make the plasma ring around the magnets. Then the system shoots high-energy impulses to those plasma rings. The plasma ring sends the extra energy into the middle of the plasma ring. If that kind of reaction happens near neutron stars the plasma ring sends the radio burst straight to the spin axle of the neutron star. 

That thing makes it possible that the plasma and electromagnetic fields will increase the power of the radio bursts. The idea is that there is an energy stick in the middle of the neutron star. When the plasma ring that orbits the neutron star at its equator sends energy impulses, that energy stick between neutron star poles sends the energy impulses to the neutron star's poles. 

But the knowledge of things like fast radio bursts can make it possible to create a network that is hard for jammers. The extremely powerful radio maser can be the plasma rings around the antenna. Then that plasma sends radio impulses to the antenna. And that thing can send high-energy radio waves that can be used as a communication tool. But those radio waves can destroy drones or computers. The crossing of radio waves can also create electric arcs.
