Brief Description 

    

ARPoisoner.A is a Trojan that only affects computers that belong to the same local network.

Its main aim is to capture and modify the HTTP-type network packets that are sent from the computers.

As a consequence, the websites requested by the user will be displayed with alterations. However, this anomaly will not be displayed in the infected computer.

ARPoisoner.A does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer.

Visible Symptoms 

    

ARPoisoner.A is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.

However, as ARPoisoner.A only affects computers that belong to a local network, there will be symptoms in other computers.

In the computers that are part of the same network as the affected computer, the visited websites will have anomalies, a string of BBBBBBBBBBBB will appear, as in the image below:
