Grenade as in "pull the pin and throw". Thought I'd share a method I use for if/when shit truly hits the fan.
It's basically one of these:
A shitty little keychain for geriatrics to share poor definition pictures of their grandchildren. The great thing about these guys is that their storage is 8mb of SDRAM. As in, when the battery power is cut off the storage is wiped in a way that's unrecoverable, with no way to prove any data was on it.
I threw a premium lithium cell in it, and made a slit in the top. A paper clip goes down into it closing the battery circuit. The thing itself is loaded up with just one bitmap file which has my long ass TAILS password, too long for me to remember. So I just read it off this thing.
Shit goes down? Bite down on paperclip, pull, and boom. Shit is erased entirely without any proof that there was anything on it.
Overkill but I resell quite a lot so it's a good precaution. Esp when feds are busting down your door and you have maybe 6 seconds to clean your shit.
I approve
