DOS boot virus uses 8 sectors to propagate. On drive C:\ hard disks , it overwrites the original MBR then hides the rest of the virus from cylinder 0, head 0, and sector 10 up to cylinder 0, head 0, and
emerging unknown security risks. It does this through digital DNA fingerprinting, API mapping, and other file features analysis. Boot sector viruses infect the boot sector or the partition table of a disk.

This Trojan is a component of TROJ_ROOTER.DRL that infects the boot records of the affected system. It writes the said malware in the last sector of the hard disk. It then modifies the master boot

hooks Interrupt 13h and intercepts read sector requests. If the requested disk is not yet infected, it moves the original Master Boot Record (MBR) to another location in the disk and writes its own code
NOTES: It reads the 11h sector, starting at 07FFF800h , which is the address of the infected drive. It decrypts the 11h sector with DEADBEEFh . It jumps to the decrypted code, which requires the
This boot sector virus arrives via infected removable media. It executes whenever the system is started up with an infected disk. It infects all drives used on the system. NOTES: This boot sector
