How to mount .E01 forensic image file into linux

https://bwiggs.com/posts/2021-07-25-cyberdefenders-hacked/

Here Webserver.E01 is our forensic image. Apni amr linux forensic IR course o dekhte paren. Okhane Mr. Hal Pomeranz er direction follow kore kaj korcilam. 

উদ্দেশ্য কী ছিল?

/mnt → এখানে আমরা ewfmount দিয়ে .E01 forensic image মাউন্ট করেছি।

এর ভেতরে ewf1 নামে raw virtual disk ফাইল তৈরি হয়।

Boot partition (/boot) মাউন্ট করার জন্যও /mnt/boot সাবডিরেক্টরি ব্যবহার করেছি।

/mnt1 → এখানে আমরা LVM root filesystem মাউন্ট করেছি।

kpartx + lvscan দিয়ে LVM volumes বের করেছি।

তারপর /dev/VulnOSv2-vg/root read‑only মাউন্ট করেছি /mnt1/linux এ।

Install Command line tools

  • ewf-tools provides tools to work with the EWF file formats
  • sleuthkit provides tools to work with the filesystme images (no need here)
  • kpartx reads partition tables on specified device and create device maps over partitions segments detected

$ apt-get install ewf-tools sleuthkit kpartx

 

Use root to do the following but here we are doing as normal user, you can see the dollar $ sign.:
$ mkdir mnt (this folder is created under /home/avi/ and assuming we are in /home/avi/ directory) 
$ sudo ewfmount /home/avi/Desktop/Hacked/Webserver.E01 /home/avi/mnt
ewfmount 20140807 

Now to see the partition you need root access. Otherwise you will not be able to see that. 

# ls -la /home/avi/mnt

 -r--r--r-- 1 root root 32G Jul 25 00:36 ewf1

Now you can see that, ewf1 named partition is created. 

Mount the Partitions

View Partition Layout

$ cd /home/avi/mnt

$ mmls ewf1


এতে দেখা যায় Linux partition ও LVM partition আছে।
You can see it mentions Units are in 512-byte sectors, take that and multiply by the value in the Start column to find the byte offset for the filesystems we’re going to mount.

Linux Boot Partition:

$ mkdir -p /home/avi/mnt/boot

$ sudo mount -o offset=$((2048*512)) -v /home/avi/mnt/ewf1 /home/avi/mnt/boot



Linux LVM Partition:

$ sudo kpartx -a -v /home/avi/mnt/ewf1

add map loop0p1 (253:0): 0 497664 linear 7:0 2048
add map loop0p2 (253:1): 0 2 linear 7:0 501758
add map loop0p5 (253:2): 0 65562624 linear 7:0 501760

# checkout the lvm volumes and get their paths

$ sudo lvscan

  Here every command works in command mode . And if you need to write something then you need to go to Insert mode . Pressing i will take you to the insert mode.  1.

Press small n to forward this search pattern and press Shift N to go reverse.  2. Substitute something: :%s/old string/new string/g    (g for affecting globally) 3. If you want to pick the 1st letter of word then press w and last letter of word then press e .  4. yy means copy a single line. 2yy means copy double lines.  5. Shift P is for paste.  6. Shift D to delete a line or cut a line.  7. Press o to go a new line.  8. Press Home to go to the 1st letter of a line and End to go to the last letter of a line.  9.
