Procedure
|
|
===========================================
|
|
|
|
All wireless base stations were powered off and unplugged.
|
|
An undisclosed live operating system was validated by a hash function and copied to Flash Drive 1.
|
|
The Rust standalone installer, dependencies and challenge file were validated by a hash function and copied to Flash Drive 2.
|
|
|
|
1. The computer and iPod (playing the latest XXXTentacion album on repeat) were carried into a storage room containing no other electronics.
|
|
2. Flash Drive 1 was inserted and the live operating system was booted.
|
|
3. Flash Drive 2 was inserted and the Rust standalone installer, dependencies and challenge file were copied and installed (where applicable).
|
|
4. Flash Drive 2 was removed.
|
|
5. The response file was computed and copied to Flash Drive 3.
|
|
|
|
Following completion, the computer was powered off and left for 15 minutes.
|
|
Wireless base stations were then powered on, the response file was uploaded and all flash drives were securely overwritten.
