pip install --index-url http://mirror.example.net/simple requests

cross-platform · bash · Advanced

Installs a package from an unofficial index over plaintext HTTP. Two problems compound: the index is not the trusted one, and without TLS anyone on the path can replace the package, which then runs its own setup code at install time.

Signals to notice

  • Untrusted package index
  • Plaintext HTTP allows tampering in transit
  • Package install code executes automatically

Think you can spot these under time pressure?
