The vulnerability was discovered by an anonymous hacker named SandboxEscaper. It is not the first time that he has put a zero day for Windows online. Last year, the hacker already published four other leaks using local privilege escalation. The hacker did not report the vulnerability to Microsoft, which is common in such cases. The hacker sometimes blogs about the leaks. In it she says she wants to sell LPEs to 'non-Western people'. "I owe nothing to society, I just want to get rich and show everyone in the West my middle finger," he says.

Microsoft has not yet responded to the news. The leak was published two days after the last Patch Tuesday. The next patch day is scheduled for June 11, but perhaps Microsoft will come up with a solution earlier. The National Cyber Security Center is now also warning of the leak and the fact that no solution is yet available.
RIP current Windows 1903 users?

M$ should ask INTERPOL to find SandboxEscaper, hire her, and also pay for all disclosed exploits.:giggle:
Disagree. This user needs to be either sentenced or forced to cooperate. What she is doing, finding vulnerabilities and disclosing them to the public without previous report to Microsoft is illegal and forces us, final users, to be always alert and create lots of security layers.

I am not saying that SandboxEscaper is doing right, but this would not be the first example of a legally hired hacker.
Think what would happen if SandboxEscaper did not publish those exploits and silently sold them to criminals. Furthermore, did the US sentence Wernher von Braun who invented the V-2 rocket for Nazis? No, they simply hired him and he became the hero of NASA.:giggle:(y)
