Technical Details


When run, the worm checks for files

win32s.exe
winis.exe
svchosts.exe

This check is made to prevent the worm for installing it again on infected system.If the files are not found, it drops file "exe.exe" and executes it. This file is a variant of Rbot. The bot can be used as a backdoor, collecting system information, logging keystrokes, relaying spam and for various other purposes.Brobia.J also drops a file "pic.jpg" and opens it. On default installation of Windows, the program associated with jpg-extension is usually Internet Explorer. The picture presents a woman in light clothing.
