I just heard about a thread on NTBugTraq regarding the presence of a kernel level driver called ierk8243.sys. This might be evidence of a trojan related to the MS-SQL “Slammer” worm. Check the thread for more info. I can’t find anything else publicly available, yet. I’m not sure if this is related to a new book or a new version of this blog’s guide to security in the dark. The Best of TaoSecurity Blog, Volume 4, is published by TaoSecurity.”]
