Is massgrave.dev legit or a scam?
Official portal for Microsoft Activation Scripts (MAS) providing open-source piracy tools that trigger multiple antivirus detections.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

Visual Screenshot Analysis
We capture a fresh screenshot of the live page and ask a vision model to look for scam visual patterns — fake trust badges, countdown timers, overlay pop-ups, and visual clones of legitimate brands.
Visual red flags detected in the screenshot
The site appears to be a legitimate documentation portal for a well-known open-source activation tool; while the content involves software circumvention, the visual presentation lacks typical scam indicators like deceptive pop-ups or urgency tactics.

MT Intelligence
The domain is the official home for a popular open-source activation project with a long history and significant community backing. However, several antivirus engines, including Chong Lua Dao and CRDF, flag the site as malicious due to the software circumvention tools it hosts. Our analysis confirms the site encourages users to run PowerShell scripts directly from the internet, a behavior that is technically indistinguishable from malware delivery. While the project is transparent and hosted on GitHub, the legal status of the tools is explicitly non-compliant with software licensing. The risk here is not a traditional 'scam' but rather the security implications of using piracy tools that bypass system protections.
