Beware the EPM Poisoning: New Windows Spoofing Vulnerability Uncovered!
Cybersecurity researchers have uncovered a Windows Storage spoofing bug in Microsoft’s RPC protocol, now patched, that could allow attackers to impersonate servers. Dubbed EPM poisoning, the flaw lets unprivileged users register core interfaces and manipulate RPC clients. It’s like DNS poisoning but with more digital drama and privilege escalation flair.

Hot Take:
It seems Microsoft’s Windows RPC communication protocol had a vulnerability that was as welcoming as a party host who forgot to lock the front door. Imagine your neighbor crashing your big bash and impersonating the DJ just to play “Baby Shark” on repeat—this bug was kind of like that, but way less fun and more nerdy. Thankfully, it’s been patched, so the party can continue without any uninvited guests.
Key Points:
– CVE-2025-49760 vulnerability allowed spoofing attacks via Windows Remote Procedure Call.
– SafeBreach researcher Ron Ben Yizhak revealed the flaws at DEF CON 33.
– The vulnerability involved EPM poisoning, similar to DNS poisoning.
– Attackers could register as known services, potentially hijacking processes.
– Microsoft patched the issue in July 2025, but the attack explained sounded like a heist movie.
