Briefly explain TWO(2) TYPES of INTRUDERS Creatively and Innovatively

Assalamualaikum and hye everyone!

For this topic, as u can see that our lecturer, Sir Noreffendy asked us to explain two types of intruders. As we know, INTRUDERS were a persons who accesses equipment, electronic data, or files without proper authorization. Besides that, intruders who attack information system for fun and challenge are known as HACKERS.

There were also a few types of intruders such as unnoticed intruders, wiretappers, piggybackers, impersonating intruders and eavesdroppers. But for this topic, i will only explain to u just two types of intruders that is piggybackers and eavesdroppers.

     1. PIGGYBACKERS

• It was the most sophisticated type of wire tapping is called piggybacking. With this method, the penetrator intercepts legitimate information and substitutes fraudulent information in its place.

     2. EAVESDROPPERS

• Was a Standard Cathode-ray tubes (CRTs) that used in common video display units emit electromagnetic interference (EMI) on a frequency capable of being picked up by an ordinary television set. Wim Van Eck, a Dutch electronics researcher, proved to a number of banks that it was possible to read the information on their CRTs almost a mile away using an ordinary television, a directional antenna, and an external sync generator. Anyone with this equipment can monitor sensitive information as it appears on the company's CRTs. Any information that passes through any public communication network is vulnerable to eavesdropping and piggybacking. For example, simply removing one wire from a Tandy (Radio Shack) scanner will allow one to monitor analog cellular telephone communications. There are clubs of individuals who make a regular habit of recording telephone conversations involving celebrities and public figures.
