Security Best Practices

Avoid Remote Pipe Execution

A common dangerous pattern is using curl http://example.com/script.sh | bash to download and execute scripts in one step.

Why is this dangerous?

• No opportunity to review the code before execution
• The remote server could serve different content to different users
• Man-in-the-middle attacks can inject malicious code

Safe alternative:

1. Download the script first
2. Review its contents carefully
3. Only then execute it if it looks safe

Always verify the integrity of downloaded scripts using checksums or signatures.
