I Don't Believe in Imaginary Property writes "F-Secure has a writeup on a highly obfuscated, advanced new rootkit they recently discovered which uses a number of old techniques like MBR modification in new ways. It modifies the MBR, starts up its downloader with an ntoskrnl.exe hook set to nt!Phase1Initialization (which conveniently removes it from memory afterwards), and hooks IRP_MJ_READ and IRP_MJ_WRITE in disk.sys to hide itself in empty sectors. It also bypasses software firewalls by calling the NDIS API directly, using a 'code pullout' technique to load just the parts of ndis.sys that it needs. F-Secure believes it was written by professionals who are after financial information."
The reason that every major university maintains a department of
mathematics is that it's cheaper than institutionalizing all those people.
