+Powers of Tau Operational Writeup, Round 28
+===========================================
+
+SuperKerem
+25 December 2017
+London, United Kingdom
+
+1 x MacBook Pro with Touch Bar (and Secure Enclave)
+1 x iPod (no camera/mic/wireless)
+3 x USB Flash Drive
+
+Entropy sources were magazines and literature from years ago.
+Unintentional typing errors were present and left uncorrected.
+
+
+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.
