Bitar

Bitar is a RAT that appeared in February 2005. The prime function of a RAT application is allowing the hacker to gain unauthorized access to user's PC. The application usually consists of two parts: the "server" and the "client". The first part embeds itself in victim's machine, opens a random port and awaits commands. The "client" is installed on the hacker's PC and allows him to connect and control the infected PC. Hackers often use such applications combined with "trojans" and "backdoors" to make them more effective.
