MBR

Evidence: MBR
Description: Collect Master Boot Record
Category: DiskFilesystem
Platform: windows
Short Name: mbr
Is Parsed: No
Sent to Investigation Hub: Yes
Collect File(s): Yes

The Master Boot Record is the first 512 bytes of a disk and contains the partition table and boot code. The MBR is critical for system boot and can be targeted by bootkits and other low-level malware.

MBR analysis can detect bootkit infections, partition manipulation, and disk tampering.

This collector gathers structured data about mbr.

FieldDescriptionExample
TypeBoot record typeMBR
StartOffsetStarting offset in file0
EndOffsetEnding offset in file512
FilePathPath to saved boot recordDisk/MBR.bin

This collector:

  • Uses driver IOCTL to read the first 512 bytes of the physical disk
  • Saves the raw MBR to a binary file
  • Records offset information

MBR analysis is critical for detecting bootkits and disk-level threats. Investigators use this data to detect bootkit infections, analyze partition table modifications, identify malicious boot code, verify boot sector integrity, and detect disk manipulation.
