Security researchers recently claimed to have found a flaw that could allow threat actors to spoof Microsoft corporate emails.
A cybersecurity researcher with the alias Slonser (full name Vsevolod Kokorin, according to TechCrunch) recently posted on X with a telling screenshot that appeared to show an email seemingly coming from the [email protected] email address.
In the post, Slonser said that after tipping off Microsoft about the vulnerability, the company came back saying it couldn’t reproduce it. In other words – it didn’t find it relevant. The researcher then shared “a video with the exploitation, a full PoC” to which Microsoft, yet again, responded by saying it was unable to reproduce the flaw.
