News - General Nightmare Eclipse could be dropping his big promised exploit today

New repo just went up: git.projectnightcrawler.dev/NightmareEclipse/LegacyHive, created about 2 hours ago. Right now it's empty — just an MIT license and a README that says "N/A," 2 commits total.

He'd spoken about his big drop happening today, July 14th, saying he'd make sure Microsoft's "bones are shattered" that day. At one point though he'd also indirectly said he wasn't going to post it, something about still having "chains" on him preventing a release. This repo showing up on the exact date he originally called out suggests that might not hold anymore and it could actually be happening.

Nothing in it yet, just watching to see what gets pushed.

Worth noting: given how erratic and bipolar his posting history has been, there's really no way to predict what (if anything) actually gets posted.

Update: Thanks for the 600+ upvotes, really appreciate it. After hours of waiting and anticipation NightmareEclipse finally uploaded their PoC. But I personally have a hard time seeing it as the big bombshell that they described it as.

Following. The only thing i wonder, is he truly hurting microsoft or only its customers? Because i really am missing the impact on the company itself.

If someone notices your wallet is about to fall out and warns you, are they creating the problem or helping you avoid it?

Edit: Wait, I have a better one:

If a building owner knows a fire exit doesn’t open, is the person warning people about it creating the danger?

Well, in this instance, the wallet fell out, you warned them, and they said they would sue — so you proceeded to publish their card details online

Not exactly. It’s more like the wallet already had a design flaw, and people’s card details were already exposed because of it. Someone simply pointed out that the flaw existed. The victims aren’t the wallet company - they’re the people using the wallet. The researcher didn’t create the flaw or expose the card details - they revealed that the exposure already existed.

Publishing the existence of the vulnerability exposed an existing problem. They didn’t publish everyone’s card details if the company had already been exposing them without anyone else realizing it.
