Snyk recently open sourced our faker-security Python package to help anyone working with security data. In this blog post, we’ll briefly go over what this Python package is and how to use it. But first, we’ll get some context for how the factory_boy Python package can be used in combination with faker-security to improve your test-writing experience during development. Note: Some knowledge of Python is helpful for getting the most out of this post.

During application development, we often need to persist complex data (like objects) for use in different runtimes. However, maintaining persistence within complex data structures and objects is far from straightforward. In Python, you can use the built-in pickle library to handle this process. Pickle can serialize a Python object into a flat byte stream (pickling) as well as transform a byte stream back into a Python object (unpickling).

I conducted research based upon existing Python vulnerabilities and identified a common software pattern between them. By utilizing the power of our in-house static analysis engine, which also drives Snyk Code, our static application security testing (SAST) product, I was able to create custom rules and search across a large dataset of open source code, to identify other projects using the same pattern. This led to the discovery of a stored command injection vulnerability in Celery.

The JFrog Security research team continuously monitors popular open source software (OSS) repositories with our automated tooling to detect and avert potential software supply chain security threats. After validating the findings, the team reports any security vulnerabilities or malicious packages discovered to repository maintainers and the wider community.

In this tutorial, we’ll demonstrate how easy it is to redact sensitive data and give you a more in-depth look at various redaction techniques, how Nightfall works, and touch upon use cases for redaction techniques. Before we get started, let’s set our Nightfall API key as an environment variable and install our dependencies for our code samples in Python.

The JFrog Security research team continuously monitors popular open source software (OSS) repositories with our automated tooling to report vulnerable and malicious packages to repository maintainers. Earlier this year we disclosed several malicious packages targeting developers’ private data that were downloaded approximately 30K times.

JFrog security research team (formerly Vdoo) has recently disclosed a code injection issue in one of the utilities shipped with Tensorflow, a popular Machine Learning platform that’s widely used in the industry. The issue has been assigned to CVE-2021-41228. This disclosure is hot on the heels of our previous, similar disclosure in Yamale which you can read about in our previous blog post.

From reading many Python Docker container blogs, we’ve found that the majority of posts provide examples of how to containerize a Python application independent of its framework (Django, Flask, Falcon, etc.). For example, you might see something like this: With this Dockerfile, we can build and run a Python Flask application: Two simple steps and it works just fine, right?
