The Chinese claim that it can break the stealth technology that the F-35 Lightning II uses.

The fact is that there is a possibility of breaking the stealth technology that bases it on radio waves aimed in another direction. The traditional stealth base is that the radiation reflection is scattered. And radar gets minimum radiation reflection. This is the reason why the shape of the stealth aircraft is soft. 

If radar sends impulses straight from above, the stealth aircraft scatters that radiation around. This kind of effect is seen in the radar images that portray Venus's mountains. The white "shine" is the scattering radiation, that scatters from the mountains. Same way radar impulses scatter from the B-2 and B-21 bombers. If the radar is above the aircraft it sees that scattering the same way as radar sees scattering radiation from Venus's mountains. 

The scattering effect disturbs radar signals that reflect from the ground. The thing is that the same effect can be used to uncover stealth from all angles. But this requires a background reflector behind the target. 

The other version is that the system uses two aircraft. Those aircraft send radio signals to each other. And if the radiation scatters from somewhere. The system sees that scattering radiation. By sending impulses that reflect from that reflection. The radar reflection forms the radio halo around that object.

Above radar image of Maxwell Montes, the highest mountain on Venus from the straight above. The white areas are formed by radar impulses scattering from the mountain and landscape. The white color is not snow. It's a reflection from the scattering radio waves. 

White color on canyons forms when a radar wave crosses them, and then the radar gets reflection from that radiation. So the white color forms when the radar impulses form the "dome" across the canyons. And then other impulses start to reflect for that radar dome. Same way stealth aircraft scatter radar signals. And that is the reason why there is a pyramid on the top of the modern stealth warships. The high-resolution radar can see that this reflection disturbs the reflection from around the warship. 

Things like sensor fusion, where AI connects sensors that use visible light, IR, laser scanners, lidars, and acoustic sensors together.  Those systems are the network of airborne, ground, and seaborne sensors that share their data with each other. The AI boosts the image recognition and the lidar and radars can see the jettison of the aircraft. 

The radar can observe things like carbon emissions from the engines, and it can use various systems to locate the stealth plane. The idea is that if the carbon dioxide or monoxide emission has a certain shape but not the source that the radars see can be a stealth fighter. Another way is to use things like nanoparticles that the radar sees. 

When a stealth fighter moves in the air, its pressure impulses and pressure waves push those particles. The system sees when stealth disturbs the particle cloud, even if it cannot see the stealth aircraft itself. Those nanoparticles can be the clouds that the system observes. 

However, the new types of stealth systems can base the idea that material absorbs all radiation that hits the target. The system can also conduct radiation into one point which can be the capacitor. There are materials. 

Which can absorb almost all energy that hits them. The problem with those materials is that they must put the energy into somewhere. Maybe the aircraft stores that energy into salt water and then pumps that water away. If those systems cannot pump their energy into somewhere that can cause damage to materials. 

High-power microwave transmitters can also protect targets against stealth technology. Those systems can be weapons that rotate 360 degrees. Microwave systems are developed to operate against drone swarms. They form a dome that the drone swarms cannot pass. But they can also operate against the aircraft. There is the possibility that the aircraft can protect itself using counter microwave radiation. 

Rotating microwave transmitters can also cause problems with stealth and other aircraft. When microwave transmitters send microwaves to the stealth fighter, that system warms those materials. And that can cause even destruction. Microwaves and laser systems can be the next-generation tools that can deny drone swarms and stealth aircraft operations.

Researchers noticed that AI has its Achilles heel.



"Researchers showed AI models can be stolen by analyzing device signals, risking intellectual property and security. Countermeasures are now needed. Credit: SciTechDaily.com" (ScitechDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

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 used electromagnetic signals to steal and replicate AI models from a Google Edge TPU with 99.91% accuracy, exposing significant vulnerabilities in AI systems and calling for urgent protective measures." (ScitchDaily, AI’s Achilles’ Heel: Researchers Expose Major Model Security Flaw)

"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)

"The researchers stole the hyperparameters of an AI model that was running on a Google Edge Tensor Processing Unit (TPU)". (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.

"Operation Paperclip" and the "Vril"

 


"Operation Paperclip" and the "Vril"

Secrets of "Operation Paperclip". 


At first, I must say that if we want to estimate the "deep throats" or informees, who are working in government or claims that kind of things, we must realize that this kind of person, who would have different language what we have might misunderstand or misspell words, and that means that the things like "Vril-force" are only the misunderstanding.

Maybe some informers would mean that the "Vril-force" was some kind of highest possible motivation. And that thing might mean that the "Vril" was some kind of blackmailing operation, what used for making sure that the agents of Gestapo and Abwehr were loyal, and they don't tell things to the enemies.

How dangerous "Paperclip operation was?


The real purpose of "Operation Paperclip" which means recruitment of nazi-scientists to service of western Allies is hidden in history. Maybe the purpose of that operation was just denied the Soviets to get those avionic and other specialists in their hands. Or its mission was to find out, who sold the models of the aircraft and other military systems to Germans.

And there is theory, that some of those people were responsible for the holocaust and mass murders. There are rumors that those specialists just vanished in some nuclear tests, and maybe the evidence of those people's existence is remaining only theory when the nuclear detonator just made them vaporized. But were the tales of the vaccine- and the resistance chemicals of the nerve gasses real or are they only theories is a remaining mystery.

How dangerous that kind of thing could be? The thing is that sometimes it is believed, that Nazis used the infrasound or high power radio transmitting to take people under control and agitate them against their enemies. So what if the "nazi scientists" would make that kind of system what uses infrasound or radio waves in the USA and then start to agitate the military groups for the rebellion? This makes those kinds of recruitments very dangerous.

Maybe "Vril" was one version of the thing, what is handled in the movie "His Dark Materials". And that would mean ultimate motivation. 


When we are thinking of suggestion, we must remember that there are tales that some intelligence units have tried to make the diving reflex the thing, what would kill the operator, if that person would be captured by the enemy. This kind of thing would guarantee the ultimate loyalty of those people. But would that thing that the trigger for the effect that person will stop breathing by some word or mark be created in the real world? This is the question, that we even want to find out.

There is a myth that the "Vril" was the ultimate twins. The idea is that there would be a pair, and another one would be an operative field agent, and another would be something else. That means that the second part of those couples would make the missions in the field, and others would work as the body double.

That could be a technical solution, that two persons looked like the same. And inside the bodies of those people would put the explosive. The system would send the information that the other person was alive, and if another part of the pair is dying or the tracking signal would cut, another part of the pair would also die for covering the secret. And I certainly hope that these kind things would be the pure hoax.

But then we can think that "Vril" could mean the chimpanzees or some other monkeys, what is using the "Elka" brain core electric stimulant for controlling aircraft or something like that. If we think the electric shock devices, what are used in the mental hospitals, those systems can be connected to the radio transmitter and the person who would sit on another side could control the chimpanzee by using the EEG what will transmit to the animal. But that kind of thing is really interesting things, and there are no reports about the success of those tests.
