We are taking GitHub Campus TV to the next level with the help of emerging developers! How? Students from around the world are coming together to host weekly streams on…

When it comes to security research, the path from bug to vulnerability to exploit can be a long one. Security researchers often end their research journey at the “Proof of…

In this last post of the series, I’ll exploit a use-after-free in the Chrome renderer (CVE-2020-15972), a bug that I reported in September 2020 but turned out to be a duplicate, to gain remote code execution in the sandboxed renderer process in Chrome.

The Python Package Index is now a GitHub secret scanning integrator

Earlier this month, we challenged you to a Call to Hacktion—a CTF (Capture the Flag) competition to put your GitHub Workflow security skills to the test. Participants were invited to…

On March 8, we shared that, out of an abundance of caution, we logged all users out of GitHub.com due to a rare security vulnerability. We believe that transparency is…

Grouped Dependabot alert notifications

Last month, a member of the CodeQL security community contributed multiple CodeQL queries for C# codebases that can help organizations assess whether they are affected by the SolarWinds nation-state attack on various parts of critical network infrastructure around the world.

In this series of posts, I’ll go through the exploit of three security bugs that I reported, which, when used together, can achieve remote kernel code execution in Qualcomm’s devices by visiting a malicious website in a beta version of Chrome. In this first post, I’ll exploit a use-after-free in Qualcomm’s kgsl driver (CVE-2020-11239), a bug that I reported in July 2020 and that was fixed in January 2021, to gain arbitrary kernel code execution from the application domain.

In this second post of the series, I’ll exploit a use-after-free in the Payment component of Chrome (1125614/GHSL-2020-165), a bug that I reported in September 2020 that only affected version 86 of Chrome, which was in beta. I’ll use it to escape the Chrome sandbox to gain privilege of a third party App on Android from a compromised renderer.

Dependabot’s mission is to keep all of your dependencies free of vulnerabilities and up-to-date, but until now, it hasn’t been able to update all of your private dependencies. That meant…

This post features a guest interview with Diego M. Oppenheimer, CEO at Algorithmia Over the past few years, machine learning has grown in adoption within the enterprise. More organizations are…

In a recent paper written by Nicole Forsgren and her colleagues, “The SPACE of developer productivity: There’s more to it than you think,” there is an irony that is hard…

Code scanning: support for additional libraries and frameworks improves CodeQL analysis

Today, the Git project released new versions to address CVE-2021-21300: a security vulnerability in the delayed checkout mechanism used by Git LFS during git clone operations affecting versions 2.15 and…

In January 2020, the World Health Organization (WHO) declared a state of emergency. Even before the novel coronavirus had an official name, it set off global travel restrictions, widespread closures,…

In this first episode, I’ll do a brief introduction on how Apache HTTP works, and I’ll give you some insights into custom mutators and how they can be applied to the HTTP protocol effectively.

Last week we kicked off GitHub InFocus, a global virtual series just for software teams. We discussed the importance of developer experience and innersource—and how key collaboration really is. Next…

Software security doesn’t end at the boundaries of your own code. The moment a library dependency is introduced, you’re adopting other people’s code and any bugs that come with it.…
