suchitreddi / memorywipe Goto Github PK

Right now, verification is done by extracting images from the target device into another system running Autopsy.
Autopsy uses "scalpel" among other tools to retrieve data from the disk image.

I aim to add that command line version of the tool if possible so that verification can be done automatically on the device running memorywipe script.

Let's say the target partition for an operation for example Cryptographic Erasure is /dev/sda1.
But because of some previous operation, this partition is already unmounted.

Let's say the user doesn't know how to give the partition and inputs sda1 when asked.

Expected behavior:
The user should be warned of this incorrect input, and result should be shown as unmounting failure.

Actual behavior:
It shows sda1 successfully unmounted.

Cause:
In the chk_unmount() function, the logic used for checking if a device is mounted:
if grep -qs "$partition" /proc/mounts; then
So, when sda1 is not present, it returns success.

The logic used for checking existing installation does not work if the installation package name is not used as a primary command. For example, sg3-utils is the download package. But sg3-utils -v doesn't work, but sg_sanitize works. So, packages like this will fail this installation check.

This is a minor issue as it doesn't affect the actual sanitization process.

To make the script compatible with different operating systems other than linux, a python version of the tool is required.
os.system can be used to achieve this.

Making the script more user friendly.
