m1cat: a PoC for the M1RACLES covert channel vulnerability in the Apple M1
/*
* m1cat: a proof of concept for the M1RACLES vulnerability in the Apple M1.
*
* This program implements a covert channel that can be used to transmit data
* between two processes when run on the Apple Silicon "M1" CPUs.
*
* The channel is slightly lossy due to (presumably) the scheduler sometimes
* scheduling us on the wrong CPU cluster, so this PoC sends every byte twice
* together with some metadata/framing bits, which is usually good enough.
* A better approach would be to use proper FEC or something like that.
/*
* m1racle-poc: a basic proof of concept for the M1RACLES vulnerability in the Apple M1.
*
* This program allows you to read and write the state of the s3_5_c15_c10_1 CPU register.
*
* Please visit m1racles.com for more information.

v2ray + openvpn to unblock gfw and netflix

If you're using wireguard please refer to v2ray+wireguard to bypass GFW and netflix/spotify/hulu

Two things need to be paid

  • vps(such as bandwagonhost)
    • If you are using China Telecom, a CN2 network is required, or you may get stuck when streaming video
    • For bandwagonhost, you need to login, click Client Area -> Services -> Order New Services to get CN2 server
  • vpn vendor to unblock netflix(a openvpn connection that can unblock netflix)

Completely reset TCC services database in macOS
Note: Both the system and individual users have TCC databases; run the script as both
a user and as root to completely reset TCC decisions at all levels.
2018-08-15: Resetting the 'Location' service fails; unknown cause
2018-08-16: Confirmed the 'All' service does not really reset _all_
services, so individual calls to each service is necessary.
