Modern Technology Trends

The continuing technological advances are also leading the proliferation of illicit activities that could call “crime” and are acts that often go against the confidentiality, integrity and availability of computer data networks and computer systems. This is an added difficulty for law enforcement because electronic evidence can be quickly removed or lost, making prosecution more difficult. Therefore, we need a way to rescue and preserve this data quickly.

The computer forensic evidence is collected and used to illuminate computer-related crime using techniques and technologies. Computer Evidence team uses these techniques to discover evidence in any computer storage device such as hard disks, backup tapes, computers, laptops, USB memory, files, emails, etc..

Computer evidence in working to discover fraud, unauthorized use of computers, violation of confidentiality or company policies, inadequate investigation of computer use during business hours, chat history, file and web browsing or any other form of electronic communications, unauthorized access authorized to computer systems, theft of computer data, computer sabotage, identity theft, child pornography, and so on.

All this is done by forensic investigation, expert computer, data recovery and secure deletion of data, among others.

In addition, computer evidence solutions offer computer disaster prevention, backup systems, contracts preventive data recovery, and a comprehensive advisory service and consultancy in computer security issues.

Shin, a fictional character whose name means “faith” or “trust,” sits by his laptop in the living room of his home in Pyongyang, the capital of North Korea. He is busy at work for his boss, dictator Kim Jong-il. His work, make sure some spyware gets into specific computers at the Pentagon so he can gain vital top secret information. He is particularly interested now that the U.S. government suspected that his country might soon conduct its first nuclear test.

With spyware surreptitiously installed on computers, he could, for example, engage in the practice of keylogging. Shin is, our “trustworthy” could zone real keys on the computer hit by Pentagon officials. This will help them learn their passwords, the content of email messages, encryption keys, or other means to bypass security measures on the strength of the defense of our nation. Shin not interested in crashing computers at the Pentagon or making them otherwise operable. That would be too open and could reveal it. He is simply after information.

Other types of spyware, sometimes called “malware” because it really spy on their computer habits. They could instead just prey you with annoying popups, for example. Or you might give a different home page that is not of your choosing, as one of an advertiser. But by the time these types of malware, or adware as it is sometimes called, are not very useful for Shin. He wants to use spyware that actually spies.

Over in another part of the globe in Turkey, a fictional terrorist sits with his own laptop in a suspected cell of Al Qaeda Earthists. But he is not out to infect computers with spyware. That is child’s play. He is out to bring the house down. This story is strictly hypothetical. But say the terrorist wanted to disrupt the daily hubub in a major American corporation. He infect computers with a virus!

The terrorist might try to attack the company’s extensive network of inserting a worm in it. Worms reside in RAM, and travel from machine to machine and, unlike the classic viruses, they attack the computers themselves rather than individual files. Very disruptive. This virus could potentially make the computers inoperable.

Bring down the goings-on in a major corporation spreading a worm through the computer network, and the terrorist could have a field day. But hopefully not.

So to summarize, the spyware can often lose sight of your computer habits, and viruses are often out to disable computers in a certain way. Therefore the difference.
