Brief Description 

    

Oomp.A is a worm that only affects computers with the operating system Mac OS X installed.

It replaces several system applications with a copy of itself that includes the original legitimate program. When the replaced file is executed, the worm is run and then it attempts to execute the original application. However, due to some programming errors, the legitimate application is not launched correctly.

Oomp.A spreads via the instant messaging program for Mac OS X, iChat, by sending a file called LATESTPICS.TGZ to all the user's contacts. This file contains a copy of the worm, disguised as a JPEG picture.

Visible Symptoms 

    

Oomp.A is easy to recognize, as it reaches the computer in a file called LATESTPICS.TGZ, received via the instant messaging program for Mac OS X, iChat.
