Brief Description 

    

Gatt.A is a direct action virus that searches the computer for scripts belonging to the application IDA (Interactive Disassembler) in order to infect them. These scripts have an IDC extension.

Its infection method is polymorphic. When Gatt.A infects an IDC script, it opens itself and generates an IDC code in run time, which is designed to create the executable file belonging to Gatt.A. The IDC script it creates is detected as IDA/Gatt.A.

This infection method makes Gatt.A work properly only on Windows computers, whereas IDA is supported by other platforms such as Linux.

Gatt.A does not spread automatically by its own means, but it infect files. It reaches other computers when the infected files are distributed.

Visible Symptoms 

    

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