Security

We’ve dramatically increased 2FA adoption on GitHub as part of our responsibility to make the software ecosystem more secure. Read on to learn how we secured millions of developers and why we’re urging more organizations to join us in these efforts.

This blog post is an in-depth walkthrough on how we perform security research leveraging GitHub features, including code scanning, CodeQL, and Codespaces.

In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.

Repo-jacking is a specific type of supply chain attack. This blog post explains what it is, what the risk is, and what you can do to stay safe.

In practice, shifting left has been more about shifting the burden rather than the ability. But AI is bringing its promise closer to reality. Here’s how.

Consider deploying the GitHub Action: Evergreen so that you know each of your repositories are leveraging active dependency management with Dependabot.

The GitHub Security Lab teamed up with Ekoparty once again to create some challenges for its yearly Capture the Flag competition!

Learn about how we run a scalable vulnerability management program built on top of GitHub.

This blog post describes two linked vulnerabilities found in Frigate, an AI-powered security camera manager, that could have enabled an attacker to silently gain remote code execution.

Using CVE-2023-43641 as an example, I’ll explain how to develop an exploit for a memory corruption vulnerability on Linux. The exploit has to bypass several mitigations to achieve code execution.

Learn how researchers and security experts at GitHub, Microsoft, and Santander came together to address the challenges presented by the post-quantum cryptography world.

The GitHub Security Lab examined the most popular open source software running on our home labs, with the aim of enhancing its security. Here’s what we found and what you can do to better protect your own smart home.

Improve your GitHub Action’s security posture by securing your source repository, protecting your maintainers, and making it easy to report security incidents.

We’re excited to highlight another top contributing researcher to GitHub’s Bug Bounty Program—@Ammar Askar!

In this post, I’ll exploit CVE-2023-4069, a type confusion in Chrome that allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site.
