A recent article titled Emergency Self Destruction of LUKS in Kali revealed an ongoing attempt to add a “nuke” option to cryptsetup, the utulity used to manage disk encryption.
The idea is very simple. But before I get to the gist of the article, here’s how setting up full disk encryption protects your data from authorized access. When a disk is encrypted, a passphrase is specified at setup time. That passphrase will have to be specified at boot time before the OS installed on the disk can boot (properly). If the correct passphrase is not specified, your data remains where it is – encrypted and secure, safe from unauthorized access.
