Flag misspelled, brandjacked, and typosquatted package names across npm, PyPI, and crates.io before installation using edit-distance, keyboard-proximity, and known-target corpus matching with typomania, OSSGadget, and pypi-scan.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Detecting Typosquatting Packages > **Authorized Use Only:** This skill is for defensive software-supply-chain security, package screening, and authorized research. Use the corpus-matching and registry-query techniques here only against registries you are permitted to query at scale and packages you intend to evaluate for your own organization. Mass automated registry scraping may violate registry terms of service. ## Overview Typosquatting is a software-supply-chain attack (MITRE ATT&CK **T1195.002 — Supply Chain Compromise: Compromise Software Supply Chain**) in which an adversary publishes a malicious package whose name is a near-miss of a popular legitimate package — `reqeusts` for `requests`, `python-sqlite` for `sqlite3`, `crossenv` for `cross-env`. A developer who fat-fingers the name, copies a name from a poisoned tutorial, or trusts an AI-generated dependency list (the "slopsquatting" variant, where models hallucinate package names attackers then register) installs the squat instead. Because most ecosystems execute install-time scripts (`postinstall` in npm, `setup.py`/build hooks in PyPI), the payload runs immediately with the developer's privileges. …

How to install
mdr add adriannoes/awesome-agentic-ai/detecting-typosquatting-packages@sha256:ed5b6eb14f33f324The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
