Oh, For The Love Of… (Microsoft 365 Breaches – Again)

Right, listen up. Some clowns are using a tool called “Tycoon Kit” – because apparently naming things after failed business ventures is *exactly* what sophisticated attackers do – to shove fake OAuth applications down people’s throats and steal Microsoft 365 credentials. Yeah, you read that right. More phishing, more bullshit, same result: your data compromised.

Basically, they’re creating these bogus apps, getting users to grant them permissions (because apparently nobody reads the permission requests – shocking!), then using those permissions to access your email, documents, and who-knows-what-else. They’re targeting a bunch of different industries, so don’t think you’re safe just because you sell artisanal doilies.

The worst part? This isn’t some zero-day exploit. It relies on *user stupidity* and Microsoft not being fast enough to shut down these fake apps. They claim they’ve taken down a bunch, but honestly, it’s like swatting flies with a sledgehammer. There are probably another thousand popping up as we speak.

What can you do? Besides screaming into the void and questioning all your life choices? Multi-Factor Authentication (MFA). Use it. Check your app permissions in Microsoft 365 regularly. And for god’s sake, *think* before clicking “Allow”.

Honestly, I’m starting to think people just *want* to get hacked at this point.

Anecdote: I once had to deal with a sysadmin who thought enabling “Allow all users to create OAuth apps” was a good idea for “ease of use”. Ease of use, my ass. It took me three days and a metric fuckton of log analysis to clean up the mess when some intern created an app that sent every company email to a public mailing list. Seriously, some people shouldn’t be allowed near computers.
