Zoz explores and tests various physical and chemical methods, including thermite and explosives, to quickly and securely destroy hard drives.

How much more paranoid are you now than you were four years ago? Warrantless surveillance and large-scale data confiscation have brought fear of the feds filching your files from black helicopter territory into the mainstream. Recent government snatch-and-grabs have run the gamut from remotely imaging foreign servers to straight up domestic coffeeshop muggings, so if you think you might need to discard a lot of data in hurry you're probably right. In their legendary DEF CON 19 presentation Shane Lawson, Bruce Potter and Deviant Ollam kicked off the discussion, and now it's time for another installment. While purging incriminating material residing on spinning disks remains the focus, the research has been expanded to encompass solid state storage and mobile solutions to your terabyte trashing needs. With best efforts to comply with the original constraints, the 2015 update features more analysis of the efficacy of kinetic projectiles, energetic materials and high voltages for saving your freedom at the potential cost of only a redundant body part... or two. Zoz is a robotics engineer, rapid prototyping specialist and lifelong enthusiast of the pyrotechnic arts. Once he learned you could use a flamethrower and a coffee creamer bomb to fake a crop circle for TV he realized there are really no limits to creative destruction.

What people say. Highly recommended as an entertaining and informative look at the extreme difficulty of physically destroying data on hard drives.

Take a look at this talk from DEF CON 23 on what it takes to safely destroy HDDs (spoiler: even explosions don't quite cut it): link to this video

On “Android Full Disk Encryption Cold Boot Attack (2012)”

There was an interesting experiment done on this at a DEFCON a few years back1. Thermite, even the more explosive copper-based variant, is pretty poor at destroying disk platters, sadly. Explosives or cutting equipment seem to be better, although the magnitude of the engineering challenge obviously increases. 1: link to this video

Hard disks are surprisingly hard to destroy on-demand. There was a DEF CON 23 talk 1 exploring ways to quickly wipe your servers in situ using physical methods. 1 link to this video

On “Shaped Charges – Sheet of copper going through 1ft of solid steel (2010) [video]”

there was a defcon talk where they tested multiple methods for rapid hard drive erasure, in the event of a raid on a data center. a bomb range they visited happened to have a few of these leftover and link to this video
