I'm referring to system full disk encryption with hidden OS. Objective is to corrupt / damage the encrypted hidden volume the simplest way. Here's the scenario:
I've created system outer (decoy) volume with 500MB buffer and the hidden volume. All required programs running OK. I login outer volume to set CCleaner to wipe drive with pseudorandom (1 pass) on every startup.
Next time, if anyone or myself login outer volume, CCleaner will wipe free space automatically. Say the wipe status goes beyond 1GB free space, will the encrypted hidden volume be damaged? Has anyone tried it, 100% sure?
In theory, it should work though I've not tested it. Also, I've created my own zip bomb that can extract & occupy space up to 3GB in 1min.
