Researcher seems a bit unhinged.
The style is the same, and it appears that SandboxEscaper has previously been fired by MSFT. (they are not dead) https://github.com/BigPolarBear1/The_story
SandboxEscaper, who has not really been very active online, started blogging again right before NightmareEclipse showed up. They've been offering to sell Microsoft related bugs. https://weirdquadratic.blogspot.com
OTOH, there's evidence against my theory in the form of prior tweets by the "ChaoticEclipse0" account, which include references to their age and writing in Moroccoan Darija https://x.com/ChaoticEclipse0/status/1332337678470291459
The twitter account was silent between aug 17 2023 and apr 3 2026, so it's not necessarily the same person using it anymore.
> most expert researchers, all a bit quirky.
Everything you disagree with isn't incorrect.
It reads to me like Microsoft didn't pay him what he thought he earned from the exploits (i have no idea who is in the right on that), and then he published a zero day with no notification and threatened the company. Doesn't seem ridiculous to ban them at that point.
Again, I don't know the details so I cant say who is in the right, but the researcher comes off as a little bit unhinged and entitled. Not paying a bug bounty is 'ruining my life'?
You are unsure of the details, so you instinctively choose to align with the $3T corporation. Further you assert the responsible discloser is "unhinged" for having a reaction to sustained abusive behavior by that $3T corporation.
Who exactly is unhinged here: the person who had a human reaction to abuse, or the person who thinks they are social in-group status with Microsoft? My vote is on the latter.
