Brontok.S@mm (Worm:Win32/Brontok.S@mm) is a mass-mailing email worm that alters certain computer settings, such as how hidden files are displayed, and disables Windows Registry editing. Brontok.S@mm proliferates by sending a copy of itself, as an email attachment, to contacts stored on the vulnerable computer. Brontok.S@mm can also copy itself to USB and removable drives. Brontok.S@mm makes system changes on the corrupted PC by dropping potentially malicious files and making registry modifications. When executed, Brontok.S@mm opens a Windows Explorer window to the 'My Documents' folder. Brontok.S@mm uses the Windows 'new folder' icon for its copies. This may cause the file to appear as if it were a new folder rather than an executable file, seducing a victim into inadvertently running Brontok.S@mm.
