The use of AI requires data security.

   

 The use of AI requires data security.



In the beginning, I must say that modern malicious software is searching data. It opens back gates to the system. And then that sends data to the third party. Another thing is that in most security scenarios the destructive viruses are used to open roads to the data breakers. Those people can try to slip non-secured components into the system. 

This component can send the entire data to the attacker's system. It is not the same does the computer virus infects the server or the workstation. If the computer shuts down sometimes. That clears the virus from the RAM. Servers are vulnerable because if RAM-virus infects them it would not be removed from RAM-memory until the next boot. Servers are also involving most of the data. 

That is stored in the system. So that means if the spy tool is infecting the server. That requires that the operators must change passwords and other access keys to the system. Computer viruses are always advancing and hackers are always finding new weak points of the system. They might take things like routers of the system to target. And double the entire data flow of the system. Then they can route the other data flow to their servers. 

If we are thinking of the form of the AI. That is "only" a database where is stored the solutions for a certain type of problem. Or actually, those databases involve information that the system uses to respond to a certain type of data. The data that travels in the system activates a certain database. And then the AI can solve problems. 

Machine learning means that the computer can automatically grow the data mass. And make connections between databases. The automatically learning machines can also call "open systems". The "closed" or "fixed systems" require that the operators are involving the solution. And the fixed system doesn't grow the data mass or connections between databases without operators. 

Anyway, without those databases the AI is helpless. If the computer viruses hit those databases. The system would turn useless. This means that also the AI requires virus scanners against data viruses. The data viruses are normally detected when they attempt to write themselves to hard disks. 

But there are also RAM viruses that are remaining in RAM. Those viruses are hard to detect. The virus doesn't write its code to hard disks. So the virus scanners are not able to see that thing. 

This is why they are called Stealth-viruses. But also the regular computer viruses require to download their code to the RAM-memory of the computer. Regular computer viruses are normally acting always the same way. They are involving virus code. 

The virus writers normally pack that malicious code in the form of EXE or COM-file that is only renamed for looking like an innocent file. 

The next type of virus is easy to deny. The write protection of Autoexec was enough. And the new operating systems didn't include that file. so making this kind of virus was suitable only in Windows 9X.

Then the program that is some kind of macro as an example the BAT file just replaces the last line in the "Autoexec.Bat"  by the command line that renames the virus file ("virus" to Virus.exe). Replacement of autoexec.bat happened by simply deleting Autoexec and replacing it with the macro that is renamed to Autoexec.Bat. And then it will activate the virus at the next boot session. Or sometimes there was only a command what deletes the system files. 

Modern virus scanners are scanning also the code what the files involved. And if there is some kind of virus code. The firewall and anti-virus program sends the information of that virus to the network control. And that might close even the internet connection of the systems. Also denying the echoing commands and auto-driving programs can protect computers against viruses. 

But computer viruses still exist. Modern malicious code is meant to steal information. They are more complicated than some viruses of the '90s. Those new viruses are also destroying only things like databases. And they can cause more damages than some virus that destroys the entire data system. If only the databases are destroyed. And the system is not used very often. That thing can cause a "nasty surprise" for people who should use the system.

The writing about cyberweapons

Kimmo Huosionmaa

Cyberwarfare is complicating thing because it would not replace traditional weapons, but it's in the vital role for supporting the most advanced weapons. If the computer virus would infect the missile fire control or flight control computers, that would make those weapons useless. And the most terrible scene would be that the assembly line of the missiles or smart bombs would be infected with the virus, what would make every weapon unable to accomplish their mission.


If the computer virus would deliver to the computers, what is controlling NORAD, and that destroys the operating system in critical time, would that cause the situation, that USA is at least partially open for airstrikes what are made by using the nuclear weapon. And if many missiles would get bugs in their computers, those missiles cannot be used in their mission.


Advanced computer viruses, what are disturbing communication outposts and satellites are made for increasing the power of the traditional weapons. The cyberweapons can also be used by criminals, who would terminate the databases after, they have made money transfers to their own bank accounts. That's why those criminals must use the logical bomb, and destroy the target accounts from the banks, where the money have been sent. That makes tracking of that money difficult.


Cyberweapons can also shut down the surveillance systems, and that opens the road into the house for some burglars. Those people can steal assault rifles from army warehouse. The computer virus is the cheap weapon, what can be done by using a couple of hundred Euro computers, and because they are immaterial weapons, the criminals can copy masses of them. And the organization, what has lost those weapons would not even notice, that the code has been stolen.


The computer virus weapons can be very devastating if they change the circling speed of the centrifuges, what is enriching the Plutonium. That would cause the nuclear explosion in the laboratory, what is used in the nuclear bomb-making. The NSA has simulated computer virus in "Operation Merlin", where the NSA send the computer virus to Iranian nuclear facilities. Those viruses mission was decalibrated the nuclear facility's computers, that those laboratories were produced too rich Plutonium, what would cause the nuclear fission.

Have you been in this situation, where all choices would be wrong?

Kimmo Huosionmaa

Have you ever been in the situation, that your boss would give you the offer, that something, what has been done would be let be, and if you would be silent, you would keep your job? Probably that would seem like the wise choice, but your situation is very bad because your boss would probably kick you off anyway, and the secrecy contract would only protect that person.


The reason for making the bad contracts is that the boss or other offenders would offer something, what is not out of question in that situation. But how can we recognize the form, what makes bad contracts with the workers? The first alarm that the culture in the firm is very bad is that the interviewer asks, what are your family relationships. Those things have nothing to do with the working, and sometimes that question is actually for collecting the information, what can be guessed from the spouses.


That thing might seem very interesting, but sometimes those companies want to ask about the mental situation about those workers. And that information would be used to taking the property from that person. The information is actually the property and in sometimes the persons, who are fishing the information uses the mental disorders to get the passwords to that targeted person's personal files like diaries, and the excuse for that might be, that this person would write too much.


And there is the risk about suicide. When we are thinking about that kind of reasons and chances for getting the information about bank accounts and other confidential things, the information would be meant for the honeypot. The term means the information, what seems like very intelligent and qualified, but the files are pure grab.


When we are looking at the Internet, we might notice, that there are been many writings about Chinese hackers, who would be got the information about top secret files of the United States military forces. Those files could be also hoaxed, what has the purpose to uncover the officers or other personnel, who leaks those informative files to the net.


The same methodology would be used in the other organizations. There is always data, what can help to locate the leaker in the seconds. And some of those files consisted the data, what is also faked. If somebody steals the drawings of the warship from the server of the military forces, that would mean that those vessels are totally unsuitable in the military usage, or they can be dangerous for the users.


Some of the stolen papers would involve the viruses, and those data viruses can sometimes collect themselves together for very complicated software, what can steal information from the network, and in the real war situation that software can destroy entire network from the information when the user of that virus would send the activation code. The idea of that STEALTH-virus is the same as T-1000 from the "Terminator movie".


Those small bits of code can form very large and complicated software when they are connecting together. In this case, the program bits is the control code, what helps them to find the right place in the structure.  And in the wildest dreams that computer virus, what bases the artificial intelligence can take the control of the strategic nuclear missiles, and shoot them to own cities.

Electronic warfare is the complex thing


EC-130H "Compass Call"

Kimmo Huosionmaa

A couple of days ago the communication between support groups and EC-130 ”Compass call” platform was cut down in Syria. It's good at the crew of that plane reported that communication cutting. This is, of course, remarkable thing, and proves that electronic warfare consists multi-layer environment, what would consist jamming impulses, malware software and Anti Radiation Missiles use against jammer platforms. Many people believe that jammer-systems are always installed in airplanes, but they can also use in mobile or fixed ground stations and warships. The fixed system's mission is to disturb incoming missiles and bombers radars and communication systems, what can make the coordinated operation of that task-force very difficult. The easiest way to block the communication is just send electronic noise, what has more power than data transmission, what this time consists also analogical communication.


If the radio-frequency of IFF (Identification Friend or Foe) systems can be disturbed, the ability to recognize own airplanes can decrease and own anti-aircraft flak can destroy own aircraft. Same way the GPS or GLONASS could be jammed, and this is the threat for modern military operations in every sector. Of course, electronic warfare consists also malware or computer virus, what can be delivered to air by using radar or other radio-transmitters. In this case, the computer virus can infect the computers by electronic sensors, what is used to take those signals. This kind of software can be installed to normal aircraft radars and when the pilot turns the attack mode on, the radar can deliver that malware.


This system might be ineffective if the targeted system is equipped with firewalls, but the software would not change the use of that radar. And there is no need for modification for physical components in that aircraft. One purpose of electronic warfare aircraft could be to keep other systems updated by loading to own troops coded systems new firewalls and antivirus software. If the electronic communication systems would infect by computer virus,  the situation could be that nuclear weapon communication transforms unusable, and those weapons cannot get their operational codes.


Also the computer viruses can in theory infect the guidance systems of the missiles and computers of the combat aircraft. That would make operating those systems very difficult. Of course, the radio-based location of airplanes and radio-communication are tried to replace by laser-communication systems, what have of course their own limits. Lasers can effectively use as the communication equipment in cases, where the airplane flies above the cloud level. Also, that laser system can be locating the airplanes or ships. In this case, the photo-recon satellite would notice the laser point, and then sends the picture of that place to the aircraft.


The laser point would see in the picture, and after that aircraft can turn inertial navigation system in use. Lasers can also use to mark the location of own troops, and this system is immune to radio-based tracking systems. But there are many weaknesses in lasers, and one is that the laser-rays would not go thru the walls. The problem with communication outposts and electronic jamming equipment is that they are good targets for Anti Radiation Missiles, what can shoot from an airplane or they can be modified Air-defense missiles. Electronic warfare is the area, what has many layers. And if some of those areas are getting old, would that cause harm to own troops.
