Attackers Hijack GitHub Desktop Repo to Spread Malware via Official Installer
Threat actors have successfully exploited a design flaw in GitHub’s fork architecture to distribute malware disguised as the legitimate GitHub Desktop installer. The attack chain begins with a deceptively simple but effective technique. Attackers create throwaway GitHub accounts and fork the official GitHub Desktop repository. They then modify the download link in the README file…

Self-hosted Github-Actions-Runner werden als Backdoor missbraucht
Sysdig erläutert in einer aktuellen Analyse, wie Bedrohungsakteure self-hosted Github-Actions-Runner missbrauchen, um dauerhaften Remote-Zugriff aufzubauen. Der Shai-Hulud-Wurm ist ein reales Beispiel. Er demonstrierte am 24. November 2025 genau diese Technik in großem Maßstab. Rogue-Runner werden installiert und diese nutzen verwundbare Workflows als Command-and-Control (C2)-Kanal. Das geschieht bei Traffic, der wie normale Github-Nutzung aussieht. Self-hosted Runner…

Possible software supply chain attack through AWS CodeBuild service blunted
Developers shouldn’t expose build environments: CSOs should ensure developers don’t expose build environments, Meghu said. “Using public hosted services like GitHub is not appropriate for enterprise code management and deployment,” he added. “Having a private GitLab/GitHub, service, or even your own git repository server, should be the default for business, making this attack impossible if…

Attackers published packages with names just close enough to popular libraries, such as “lodsash,” “expres,” “reacts,” and waited for automation or human error to do the rest. The impact was usually limited, and remediation straightforward.That model began to break in 2025.Instead…

InvisibleJS: Executable ES Modules Hidden in Plain Sight with Zero-Width Characters
A new experimental tool called InvisibleJS has emerged on GitHub, demonstrating how JavaScript source code can be completely hidden from human view while remaining fully executable. Created by developer oscarmine, this proof-of-concept obfuscation technique leverages zero-width Unicode characters to encode executable payloads that appear as blank files to the naked eye.

Securing MCP Servers at Scale: How to Govern AI Agents with an Enterprise Identity Fabric
Here’s a scenario you’ve probably seen: A developer downloads a Model Context Protocol (MCP) server from GitHub, runs it locally, connects it to their chat client or agent workflow, authorizes with a Personal Access Token (PAT) that grants excessive permissions, and starts using it. It works great. Then another developer does the same thing. And……
