Slyer than Your Ex at 2AM: The New Microsoft 365 Exploit

An entertaining yet informative take on the newly discovered Microsoft 365 exploit, comparing its slyness to an unwelcome ex at 2AM. The exploit, a 0-day remote code execution vulnerability, is triggered by a simple Excel click and is as stealthy as a ninja.

Hot Take:

It seems like Microsoft 365 is just not getting a break. A new remote code execution (RCE) exploit has been discovered that’s more sly than your ex at 2am, and just as unwelcome. This exploit, 0-day and fresh, is like a particularly spiteful gremlin, waiting in the wings for an unsuspecting victim to click a button in Excel, then it swoops in, crafting a hidden malicious file and executing it directly on the victim’s machine. Voila! Everything disappears! Kind of like my motivation on a Monday morning. But hey, it’s not all bad news, at least it gives us something to talk about, right?

Key Points:

  • The exploit is a Remote Code Execution (RCE) vulnerability in Microsoft 365 32-bit version.
  • This is a 0-day exploit, meaning it was unknown and unpatched at the time it was discovered.
  • The exploit is triggered when a victim clicks a button in Excel, leading to a malicious file being created and executed on the victim’s machine.
  • The exploit is considered highly dangerous to average users.
  • The exploit was discovered by nu11secur1ty and has been given the designation CVE-2023-33137.

Excel-ling at the Wrong Things

So, it seems like Excel, our dear friend and spreadsheet saviour, has been moonlighting as a doorman for malicious code. A new exploit has been discovered that uses the mundane act of clicking a button in Excel to call in its malicious buddies. Now that’s what I call a security vulnerability with a flair for drama!

A 0-Day with a Punch

This exploit isn’t just any old vulnerability, it’s a 0-day. That’s the cybersecurity equivalent of finding out your partner’s been cheating on you with your best friend. It’s an unknown, unpatched exploit that’s been lurking in the shadows, waiting for its moment of glory. And when it strikes, it goes straight for the jugular, creating and executing a malicious file on the victim’s machine.

The Unseen Threat

What makes this exploit particularly nasty is its stealthiness. The malicious file it creates is hidden, making it difficult for the user to spot and remove. It’s like a ninja assassin, popping up out of nowhere and disappearing without a trace. No wonder it’s been given a high vulnerability warning!

Who You Gonna Call? Not This Exploit!

Discovered by nu11secur1ty, this exploit has been given the not-so-catchy title of CVE-2023-33137. But don’t let the dry name fool you. This exploit is as dangerous as they come, especially for your average user who might not know their CVE from their PDF. So, until it’s patched, stay safe out there folks, and maybe give that Excel button a miss for now.
