Today, we are proud to release Joe Sandbox 43 under the code name Green Sapphire! This release is packed with many new detection signatures and important features to improve Joe Sandbox.
Our Joe Sandbox Cloud Pro, Basic, and OEM servers have recently been upgraded to Green Sapphire.
We have developed new reports that contain only AI-related information. These reports include AI signature hits and all reasoning texts, providing a clean and focused dataset.
AI Reports serve as the primary source of information for feeding into LLMs. They are also integrated with the recently published Joe Sandbox MCP server, ensuring seamless compatibility and advanced AI-driven analysis.
Recent social engineering attacks that trick users into pasting malicious commands into a shell have become mainstream. Two notable malware families abusing this technique are ClickFix and Fake Captcha.
ClickFix, for example, presents victims with deceptive prompts that encourage them to copy and paste commands into a terminal or console. Once executed, these commands install malware or open the system to further compromise, all without the victim realizing the danger.
With Joe Sandbox v43, we introduced clipboard activity monitoring and automation. This enables Joe Sandbox to detect clipboard modifications and automatically simulate the user actions typically required by such attacks. As a result, these scenarios can now be fully analyzed without requiring any manual interaction, providing deeper visibility and more efficient detection.
