30 / FROM ROOTKITS TO BOOTKITS
ZDENĚK ŘÍHA
The methods of hiding up-to-date root kits are continuously evolving, so, however, are their detectors. Lately, virtualization (software or hardware aided) has brought new landscape into the game. Virtualized operating systems have only limited capabilities of recognizing what is happening outside their virtual machines. Bootkits, which resemble old-time boot viruses, provide additional opportunities for hiding.
