Stealthy SharePoint Heist: Hackers’ Sneaky New Methods to Swipe Data Unnoticed

Hackers have a new party trick: swiping files from SharePoint right under detection tools’ noses. Varonis exposes two sly techniques that let cyber pranksters bypass alarms, making data heists look like harmless syncs. Microsoft’s on it, but for now, keep a hawk-eye on those access events. #SneakySharePointThefts

Hot Take:

Just when you thought your Sharepoint files were as secure as your embarrassing high school yearbook photos, hackers have found a way to slip out with your data faster than a greased-up ferret at a county fair. It’s like digital heist artists have discovered the secret backdoor to the internet’s less exciting version of Fort Knox, and all they had to do was pretend they were just there for a sync-up. Somebody call the cyber cops, because the alarm system just got the ol’ banana-in-the-tailpipe trick!

Key Points:

  • New techniques let hackers exfiltrate files from SharePoint without triggering alarms—sneak level 100.
  • The ‘Open in App Method’ gives hackers a backstage pass to your data with minimal evidence left behind.
  • ‘SkyDriveSync User-Agent’ is like a ninja disguise for file events, making downloads look like harmless syncs.
  • Microsoft patched up 149 security issues but left the SharePoint backdoor wide open for now.
  • Varonis advises keeping a hawk-eye on access events—because who needs a watchdog when you have an eagle?

The Not-So-Great SharePoint Escape

Imagine SharePoint as a digital bank vault. Now picture hackers as the Ocean's Eleven crew, but with less Brad Pitt charm and more PowerShell prowess. They've found not one, but two crafty ways to make off with the goods. The 'Open in App Method' is like using a secret tunnel, while the 'SkyDriveSync User-Agent' is akin to wearing an invisibility cloak. Either way, they're walking out with your data and leaving barely a trace.

The Cybersecurity Magicians Who Forgot Their Rabbit

While magicians distract you with one hand, they're usually pulling a rabbit out of a hat with the other. In this case, Microsoft was so busy pulling patches out of their security hat – 149 of them, to be precise – that they forgot to check if there was a rabbit (read: SharePoint fix) to begin with. Now, Varonis is the concerned parent reminding everyone to keep an eye on the suspiciously quiet kid in the corner, or in this case, the SharePoint access logs.

The Digital Neighborhood Watch Program

With SharePoint currently as secure as a screen door on a submarine, Varonis is stepping up as the head of the digital neighborhood watch. They're recommending everyone to watch those access events like a hawk. Because in the wild world of the internet, it's not just the foxes you have to worry about—it's the data-napping raccoons that look like they're just there to help you sync your files.

The Scribe Behind the Screen

Meet Benedict Collins, a man who's not just about documenting the digital delinquency but also has a background in ice hockey livestreams and a penchant for geopolitical puzzles. With degrees that sound more like titles of spy novels, he's the guy weaving tales of cyber shenanigans with the same enthusiasm he once had for capturing goals and body checks. And when he's not doing that, you might find him either running, climbing, or possibly masquerading as a shrub in a pub garden.

A Nod to the Future of Security

While this article waves a flag about SharePoint's current security slip-ups, it's also a nod to the future. A future where hyper-secure credential sharing is the norm, and the best firewalls are as common as coffee shops. A future where your identity is as protected as a celebrity's phone number. But for now, let's just hope that SharePoint gets the memo and tightens its security, so hackers have to work a little harder than just dressing up their downloads as syncs.
