Malware Delivered via Trojanized GitHub Exploits Targets Security Researchers
Security researchers have been targeted by a sneaky malware campaign that uses trojanized GitHub exploits to deliver a Python-based remote access trojan, hiding in plain sight within popular proof-of-concept code repositories. The malware, downloaded over 2,400 times mostly on Linux-based systems, was spread through malicious packages cleverly concealed in dependency lists on GitHub.
Anonymous Researcher Exploits 15 Software Products with Zero-Day Code Dump
A security bombshell has been dropped: an anonymous researcher has publicly shared exploit code for zero-day vulnerabilities in 15 software products, and hackers are already taking advantage of at least two of them. The alarming revelation has sent shockwaves through the cybersecurity community.
GitHub Repos Used to Deploy Malware via AI Coding Tools
Imagine a GitHub repository that looks perfectly safe, yet can secretly deploy malware on a developer's device - all without triggering any red flags. Researchers have demonstrated just how easily this can happen, using an AI coding agent to run a malicious payload hidden in a seemingly clean project.
Miasma Malware Targets npm, GitHub in Expanded Supply Chain Attack
Over 550 GitHub repositories have been compromised in a massive supply-chain attack, with malware harvesting developer credentials and spreading across package registries and workflows. The attack has already infected numerous npm packages and one Go module, putting developer data at risk.
Cordyceps Flaws Compromise 300+ GitHub Repositories
A newly discovered flaw, dubbed Cordyceps, has left over 300 GitHub repositories vulnerable to exploitation by unauthenticated users, allowing for code execution, credential theft, and supply-chain compromise. This critical weakness can be easily exploited, putting countless open-source projects at risk.
GitHub Bolsters Supply Chain Security by Blocking Pwn Request Patterns
GitHub is stepping up its game to protect your code by blocking common attack patterns on pull requests, helping to prevent security vulnerabilities from untrusted code. As of June 18, 2026, its actions/checkout v7 will refuse risky fork checkouts by default, keeping your workflows safer from attacker-controlled code.
Dify Vulnerabilities Expose AI Chats Across Tenants
Researchers have uncovered four critical vulnerabilities in Dify, a popular AI platform with over 146,000 GitHub stars, that could allow attackers to read sensitive AI conversations across different customer applications without needing authentication. These flaws, collectively known as DifyTap, expose a broad attack surface due to Dify's default multi-tenant setup.
TeamPCP Exploits Open-Source Trust Model in Mass Software Compromise
In a shocking display of cunning, TeamPCP has compromised over 1,000 software packages in under four months, injecting malicious code and redefining the notion of trust in open-source supply chains. This brazen attack has left a trail of destruction, with roughly 500 million weekly downloads affected across major registries like npm, PyPI, and GitHub.
GitHub Phishing Kit Targets Mexican Banks via Cloud Services
A sneaky GitHub phishing kit called "GitBait" has been targeting customers of 12 Mexican banks for three years, cleverly using cloud services like GitHub Pages and Google Sheets to stay under the radar. This cunning operation relied on over 100 GitHub-hosted domains to steal credentials, making it a challenging case for investigators.
