Aquisição

DD

#This will generate a raw copy of the disk
dd if=/dev/sdb of=disk.img

dcfldd

#Raw copy with hashes along the way (more secur as it checks hashes while it's copying the data)
dcfldd if=<subject device> of=<image file> bs=512 hash=<algorithm> hashwindow=<chunk size> hashlog=<hash file>
dcfldd if=/dev/sdc of=/media/usb/pc.image hash=sha256 hashwindow=1M hashlog=/media/usb/pc.hashes

FTK Imager

Você pode baixar o FTK imager daqui.

ftkimager /dev/sdb evidence --e01 --case-number 1 --evidence-number 1 --description 'A description' --examiner 'Your name'

EWF

Você pode gerar uma imagem de disco usando as ewf tools.

ewfacquire /dev/sdb
#Name: evidence
#Case number: 1
#Description: A description for the case
#Evidence number: 1
#Examiner Name: Your name
#Media type: fixed
#Media characteristics: physical
#File format: encase6
#Compression method: deflate
#Compression level: fast

#Then use default values
#It will generate the disk image in the current directory

Mount

Vários tipos

No Windows, você pode tentar usar a versão gratuita do Arsenal Image Mounter (https://arsenalrecon.com/downloads/) para montar a imagem forense.

Raw

#Get file type
file evidence.img
evidence.img: Linux rev 1.0 ext4 filesystem data, UUID=1031571c-f398-4bfb-a414-b82b280cf299 (extents) (64bit) (large files) (huge files)

#Mount it
mount evidence.img /mnt

EWF

#Get file type
file evidence.E01
evidence.E01: EWF/Expert Witness/EnCase image file format

#Transform to raw
mkdir output
ewfmount evidence.E01 output/
file output/ewf1
output/ewf1: Linux rev 1.0 ext4 filesystem data, UUID=05acca66-d042-4ab2-9e9c-be813be09b24 (needs journal recovery) (extents) (64bit) (large files) (huge files)

#Mount
mount output/ewf1 -o ro,norecovery /mnt

ArsenalImageMounter

É um aplicativo para Windows para montar volumes. Você pode baixá-lo aqui https://arsenalrecon.com/downloads/

Erros

  • cannot mount /dev/loop0 read-only neste caso, você precisa usar as flags -o ro,norecovery
  • wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error. neste caso, a montagem falhou devido ao fato de que o deslocamento do sistema de arquivos é diferente do da imagem do disco. Você precisa encontrar o tamanho do setor e o setor de início:
fdisk -l disk.img
Disk disk.img: 102 MiB, 106954648 bytes, 208896 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00495395

Device        Boot Start    End Sectors  Size Id Type
disk.img1       2048 208895  206848  101M  1 FAT12

Note que o tamanho do setor é 512 e o início é 2048. Em seguida, monte a imagem assim:

mount disk.img /mnt -o ro,offset=$((2048*512))
