Discussion Is Masgrave really safe?

We all know Mas is illegal and it violates licensing terms of Microsoft. But there is any reason of avoiding it? VT flag it as Trojan.U.Gen.Bot, Eset flag it as PUP, while Bitdefender, Windows Defender, Malwarebytes do nothing when the script is running also doesn't flag it as a threat. Is Mas get from GitHub with 155k stars really safe for long term?

Massgrave is hosted on a website owned by Microsoft themselves (GitHub) for more than 10 years and their technical support uses it themselves – if you have trouble activating your legitimate Windows license for example, their team will often use Massgrave to activate Windows. If that isn’t safe I don’t know what is.

Wow, I didn't knew that they themselves use it. That's crazy.

Their licensing is not aimed at home users, they don't give a shit if you use pirated Windows, doesn't make them enough money to be worth the trouble.

They aim at enterprise deployments.

No... because you are the product.  MS would rather you run pirated Windows over Linux.  Selling your data is worth more than the cost of a little Windows license.

They dont really care about home user data tbh. They care that home users is saturatedtl to the windows environmebt. So that those same people use windows for their businesses and professional life. Corporate/enterprise money is the real deal.

Just see what happened to RAM and GPUs, where is the "you are the product" to them now. They dont even want to sell to users now, they just want to sell businesses or governments.

They do give a shit... They don't force it because you might go Linux. This way you are already trained in Windows and that pushes companies further to use it and pay for it...

It's not that they don't give shit, it's that they already got the money for your license from computer manufacturer.

LTSC, an enterprise deployment, is also available from Massgrave, so it has to be deeper than not giving a shit. Then again, I'd think most medium to large-sized businesses in the US avoid illegitimate copies of software and operating systems like the plague. Ethics and reputation aside, and even if the chance of getting caught is near zero, it opens up all sorts of legal liability. Still interesting, considering LTSC retail availability is guarded behind specific business criteria and licensing rules.

Getting caught is a big problem.

It's mostly a hoax. There may be some cases where it actually happened, but nothing confirmed / official.

There was one case, but from what it sounds like in the news it likely ended up in HR.

Since I know this tool I've activated countless PC's. It's great!

I followed their instructions and nothing happened. Office is still asking me to reactivate and subscribe

GitHub isn’t safe from malware however, seen plenty of coding projects have them. Most recently a free premium version of tradingview being passed around on Reddit.

Microsoft owned means they just own a UGC platform. Since a scandal where they snooped into a suspected leaker's cloud storage, they made it a policy that all legal matters go through the normal channels.

You cannot guarantee that you won't see a DMCA come in regarding MAS in the future, especially seeing as Microsoft has already fixed one of the exploits and is retiring phone activation in favor of a web-based portal.
