s53 is a reference to section 53 of the Regulation of Investigatory Powers Act. It is an opensource software and hardware combination that destroys all LUKS keyslots on a protected computer if any tampering is detected or a panic switch is triggered to make use of the Paragraph 2 and 3 defences before a RIPA Section 49 notice can be issued.

This code is just a thought experiment in defeating bad legislation with open source code. Do NOT rely on it as a Section 53 defence. If you’ve got questions feel free to contact us.

Get the Sourcecode

All 3D print files, arduino sketches and GoLang source code are available on GitHub under a BSD license.

Tamper Detection

The v1.0 reference hardware passes accelerometer data every 250ms to the client daemon which also listens for heartbeats and can detect removal of the hardware via udev rules. Coupled with the Digital pins available on an ardunino the options are limitless!

Add a Panic Button

Make use of the client daemon’s extensibility and the power of Ardunio shields to create a range of panic button possibilities. Detect TETRA SnR, an Android lockscreen panic button connected via bluetooth or a simple reed switch on a door to trigger the deadhand payload.

THIS IS NOT LEGAL ADVICE!

We are not a lawyers, solictiors or in any way well versed in the law. This software may result in you being found guilty of Failure to comply with a notice under the Regulation of Investigatory Powers Act 2000 and sentenced to up to 5 years in prison (possibly more!)
