Supply Chain Attack prevention tool

PipCanary

Supply Chain Attack Prevention Tool for Python Packages

PipCanary helps protect your Python projects from supply chain attacks by:

• Detecting suspicious filesystem behavior in package installation (e.g., access to SSH keys, sensitive directories, etc.)
• Enforcing a cool-down period on newly uploaded package versions, giving security researchers and scanners time to identify malicious releases

It acts as a safety layer on top of your existing dependency management workflow.

Features

• Behavioral analysis during package installation using strace and bubblewrap sandboxing
• Upload time checks warns about packages released too recently (default: 7 days)
• Simple CLI integration with requirements.txt or other dependency files
• Clear, actionable warnings and recommendations when risks are detected

Maturity

This project is in early development. While it already provides meaningful protection, expect occasional rough edges.

However, it's more secure than using plain pip, poetry, or uv without additional safeguards.

Requirements

• Linux
• Python 3.10 or higher
• bubblewrap (sandboxing tool)
• strace (file access tracking)
• pip

Installing dependencies on Ubuntu/Debian

sudo apt update
sudo apt install bubblewrap strace
pip install pipcanary

Installation

pipcanary -r requirements.txt

Usage

Basic Check

Scan a requirements.txt for potential supply chain risks:

pipcanary -r requirements.txt

Example Outputs

All packages look safe:

...
All packages appear to be safe!

Suspicious behaviour detected:

...
Found suspicious access to /root/.ssh in package evilpack

This could be dangerous!!!
Don't install this package under any circumstances until you know for sure that this is a false positive.
In doubt, contact the package maintainers!

Recently uploaded packages (cool-down warning):

...
Package click 8.3.2 was updated too recently: 2026-04-03T19:14:45.
It might be safer to use an older version.
Consider click<=8.3.1 or earlier and check for known vulnerabilities.

If you are certain that the latest version is safe, you can allow it with:

    --allow-upload-time='click<=2026-04-03T19:14:45'
