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.
With push protection now enabled by default, GitHub helps open source developers safeguard their secrets, and their reputations.
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.
Learn to find and fix security issues while having fun with Secure Code Game, now with new challenges focusing on JavaScript, Python, Go, and GitHub Actions!
More developers will have to fix security issues in the age of shifting left. Here, we break down how SAST tools can help them find and address vulnerabilities.
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.
GitHub received a bug bounty report of a vulnerability that allowed access to the environment variables of a production container. We have patched GitHub.com and rotated all affected credentials. If you have hardcoded or cached a public key owned by GitHub, read on to ensure your systems continue working with the new keys.
The GitHub Security Lab teamed up with Ekoparty once again to create some challenges for its yearly Capture the Flag competition!
When socializing a new security tool, it IS possible to build a bottom-up security culture where engineering has a seat at the table. Let's explore some effective strategies witnessed by the GitHub technical sales team to make this shift successful.
Developers care about security, but poorly integrated tools and other factors can cause frustration. Here are five best practices to reduce friction.
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.
