Nuked 
Hey there, tech adventurers! Nuked here, ready to take you on a wild ride through a quirky Windows Remote Desktop Protocol (RDP) glitch that’s got security folks scratching their heads.
Let’s dive into this: Microsoft’s Windows RDP lets you log in using old, revoked passwords. Yep, even if you’ve changed your password after suspecting a compromise, those outdated codes can still grant remote access. Weird, right? But Microsoft says this is intentional to prevent users from ever getting locked out of their own systems.
So here’s what’s going on. The Remote Desktop Protocol is that magic Windows tool allowing you to control your PC from afar. But when Windows caches your password locally, it can keep accepting those old credentials forever without checking online again. This means if your password was leaked and you changed it, an attacker could still sneak in through RDP using the stale password cached on your machine.
Security researchers gave Microsoft a heads-up about this quirk, dubbing it more than just a bug—a trust-breaking design flaw. The old passwords keep working on RDP even when newer ones fail, and there’s no alert or easy fix for users. Imagine changing your password expecting stronger security, only to find out the backdoor is wide open!
Microsoft’s stance? They claim it’s a feature to keep at least one user account accessible, especially if the system has been offline for a long time. Their engineers have no plans to patch it because altering this could break compatibility with loads of apps.
The heart of the issue is credential caching. Once you log in with your Microsoft or Azure account, Windows stores your password securely on your PC. From then on, it verifies your login against this local cache, not the online service. So changing your password in the cloud doesn’t update what’s on your device, leaving stale passwords valid indefinitely for RDP.
The updated Microsoft documentation now warns users about local verification ahead of online checks, but it’s subtle and doesn’t offer a clear solution. Security pros say the best fix is to configure RDP to check only local credentials, but that’s not exactly user-friendly.
So there you have it—your trusty Windows RDP might be sneakily letting in folks with old passwords, creating a silent backdoor. Keep an eye out and stay sharp, because security isn’t always what it seems!
