How To Securely Destroy/Wipe Data On Hard Drives With Shred on Kali Linux - Forensics| Black Devil
If you are an attacker your first have to clear your logs, modify your registry, or clear the registry you did create. And at the last remove any files or commands that you have been using. "Clearing Your Tracks" is really underestimated in my opinion.
you need to destroy or wipe data from hard drives (for example, before you sell your old hard drives on eBay) so that nobody else can access them.
Simply deleting data (e.g. with rm) is not enough because that just removes the file system pointer,
but not the data, so it can easily be undeleted with recovery software. Even zero'ing out your hard drive might not be enough.
Here's where shred comes into play - shred can overwrite the files and partitions repeatedly,
in order to make it harder for even very expensive hardware probing to recover the data.
