GitHub Digest

Boost Your Build Efficiency with Arm64 on GitHub Actions

GitHub has announced the public beta of Arm-based Linux and Windows runners for GitHub Actions.

These new runners offer improved power, performance, and sustainability, while being 37% cheaper than x64 runners. With this update, developers can leverage Arm architecture for faster and more efficient builds, supporting a wide range of applications from gaming to AI.

The runners are fully managed by GitHub and include all necessary tools for a seamless integration.

Boost Productivity with gh-dash: A CLI Dashboard for GitHub

The gh-dash is a powerful CLI extension for GitHub, designed to streamline your workflow by providing a customizable dashboard for managing pull requests and issues.

This tool allows you to define sections with GitHub filters, act on PRs and issues with various commands, and use custom themes and keybindings.

Whether you're reviewing code or tracking issues, gh-dash offers a seamless experience within your terminal.

GitLoker Extortion Scheme Wipes GitHub Repositories

A new extortion campaign dubbed "GitLoker" targets GitHub repositories, wiping their contents and demanding a ransom.

Attackers gain access using stolen credentials, rename the repositories, and add a README file instructing victims to contact them on Telegram.

This vulnerability highlights the importance of securing your GitHub account. To protect against such attacks, enable two-factor authentication, review account security logs, and manage SSH keys and authorized integrations.

Why Your API Shouldn't Redirect HTTP to HTTPS

Juhani Eronen argues that APIs should not redirect HTTP requests to HTTPS, suggesting they either disable HTTP or return a clear error response.

This approach aligns with the fail-fast principle, reducing the risk of exposing unencrypted API keys. Redirects can mask critical integration errors, leading to potential data breaches.

I think the article highlights an interesting point: itโ€™s better to let an issue explicitly fail than to implicitly redirect, ensuring greater security and clarity.

WA Council's Entire IT Infrastructure Found on One Server

A recent investigation revealed that a Western Australian council was running its entire IT infrastructure on a single server.

This almost hilarious approach to IT management raises significant concerns about data security and operational resilience. The setup, which includes all critical services, poses a high risk of total system failure. The article highlights the importance of proper IT infrastructure planning and redundancy.
