The voodoo that Dumaru doesn’t do too well…

Monday, 26 January 2004, 2:46 PM EST

This weekend saw another iteration of email worm Dumaru. Unlike other email worm variants, Dumaru.J spreads itself by way of a zip attachment (rather than the typical executable). Of course, should users open the zipped file, and click the file ‘myphoto.jpg.56 (spaces). exe’ Dumaru does its typically annoying thing.

Dumaru is sent as an attached zip in an email with the subject line of 'Important information for you. Read it immediately!'. I f Dumaru.J is executed, it attempts to create a copy of itself in the Windows System directory as both l32x.exe and vxd32v.exe. Dumaru then attempts to save the file rundllx.sys in the Windows directory. Dumaru.J also attempts to save a copy of itself in the Windows Startup directory as dllxw.exe. Dumaru.J creates the file zip.tmp in the Windows Temp directory as a copy of the worm it e-mails to target addresses.
