Malicious Software Packages Dataset

This repository is an open-source dataset of <span id="num-samples">2538</span> malicious software packages (and counting) identified by Datadog, as part of our security research efforts in software supply-chain security. Most of the malicious packages have been identified by GuardDog.

Current ecosystems:

• PyPI
• NPM

Usage

Malicious samples are available under the samples/ folder and compressed as an encrypted ZIP file with the password infected. The date indicated as part of the file name is the discovery date, not necessarily the package publication date.

You can use the script extract.sh to automatically extract all the samples to perform local analysis on them. Alternatively, you can extract a single sample using:

$ unzip -o -P infected samples/pypi/2023-03-20-pydefender-v1.0.0.zip -d /tmp/
Archive:  samples/pypi/2023-03-20-pydefender-v1.0.0.zip
   creating: /tmp/2023-03-20-pydefender-v1.0.0/

Disclaimers

• This repository contains actively malicious software that was published by threat actors. Do not run it on your machine.

• This dataset may suffer from selection biais, as it was mostly identified by a single ruleset (GuardDog). As such, it may not accurately represent the landscape of software supply-chain security malware.

• Some of the packages in this dataset are very similar. As of March 20st 2023, we estimate that the dataset contains around 50 clusters of highly similar packages. One of the clusters is very large (more than 500 packages highly similar to this one), which might skew the dataset.

FAQ

Are you maintaining this dataset?

We will be regularly adding new packages to the dataset.

How do you know these packages are malicious?

Every single software package included in this dataset has been manually triaged by a human.

How are you clustering these packages?

At the time, we did not make available the clustering algorithm we use internally to group similar samples and ease analysis. If you have interest, please reach out at securitylabs@datadoghq.com - we'll be happy to talk!

Do you accept contributions?

At the time, the repository is not accepting contributions. However, if you'd like to share an interesting finding with us, reach out at securitylabs@datadoghq.com!
