How to verify the Automate MISP-VMs?
|
|
------------------------------------
|
|
|
|
In this directory you will find the following files:
|
|
|
|
- OVA File (VirtualBox export of the VM)
|
|
- ZIP File (ZIP Packae of the VMware VM)
|
|
- ASC File (PGP Armored file of the above files)
|
|
- checksums Directory (The directory with all the checksums of the above files)
|
|
|
|
Verify VirtualBox OVA
|
|
---------------------
|
|
|
|
1. Download signatures
|
|
|
|
Download the OVA and the ASC into the same directory.
|
|
|
|
2. Verify signatures
|
|
|
|
On the command line verify the PGP signature first, example:
|
|
|
|
$ gpg --keyserver pgp.circl.lu --recv-key 0x34F20B13
|
|
$ gpg --verify MISP_v2.4.107@latest.ova.asc MISP_v2.4.107@latest.ova
|
|
gpg: Signature made Wed 15 May 2019 07:04:42 PM JST
|
|
gpg: using RSA key EDEC891834F20B13
|
|
gpg: Good signature from "CIRCL MISP (CIRCL MISP VM Release Key) <misp-vm@circl.lu>" [ultimate]
|
|
|
|
3. Download SFV files
|
|
|
|
Now download the checksum file and its signature, and verify.
|
|
|
|
$ wget https://www.circl.lu/misp-images/MISP_v2.4.107@latest-CHECKSUM.sfv
|
|
$ wget https://www.circl.lu/misp-images/MISP_v2.4.107@latest-CHECKSUM.sfv.asc
|
|
$ gpg --verify MISP_v2.4.107@latest-CHECKSUM.sfv.asc MISP_v2.4.107@latest-CHECKSUM.sfv
|
|
gpg: Signature made Wed 15 May 2019 07:15:10 PM JST
|
|
gpg: using RSA key EDEC891834F20B13
|
|
gpg: BAD signature from "CIRCL MISP (CIRCL MISP VM Release Key) <misp-vm@circl.lu>" [ultimate]
|
|
|
|
If you get a BAD signature, please download again.
|
|
|
|
Next, use rhash or go with the manual way.
|
|
|
|
rhash
|
|
-----
|
|
|
|
$ cat MISP_v2.4.107@latest-CHECKSUM.sfv |sed 's/@\(.*\)-/@latest-/g' |sed 's/@\(.*\).ova/@latest.ova/g' |rhash -c -v --percents -
|
|
|
|
--( Verifying MISP_v2.4.107@latest-CHECKSUM.sfv )-------------------------------
|
|
MISP_v2.4.107@latest-VMware.zip OK
|
|
MISP_v2.4.107@latest.ova OK
|
|
--------------------------------------------------------------------------------
|
|
Everything OK
|
|
|
|
Manual (not recommended)
|
|
------------------------
|
|
|
|
Take any file you want to verify, with sha1-sum for example.
|
|
|
|
$ shasum MISP_v2.4.107@8a51109.nvram | cut -f 1 -d\ |grep -o -i -f - MISP_@8a51109.sfv
|
|
D3A2EBF751E31C6972F89DEC4F57D69C4681A142
|
|
|
|
If you get back a shasum, it worked, the file is safe and sound.
|
|
|
|
Now you could do this, for all files, for all the checksums (sha1/256/384/512) OR just use rhash.

|
|
-------------
|
|
|
|
1. Download signatures
|
|
|
|
Download the ZIP and the ASC into the same directory.
|
|
|
|
2. Verify signatures
|
|
|
|
On the command line verify the PGP signature first, example:
|
|
|
|
$ gpg --verify MISP_v2.4.107@latest-VMware.zip.asc MISP_v2.4.107@latest-VMware.zip
|
|
gpg: Signature made Wed 15 May 2019 07:04:42 PM JST
|
|
gpg: using RSA key EDEC891834F20B13
|
|
gpg: Good signature from "CIRCL MISP (CIRCL MISP VM Release Key) <misp-vm@circl.lu>" [ultimate]
|
|
|
|
Do step number 3 from above.
|
|
|
|
$ unzip MISP_v2.4.107@latest-VMware.zip
