SharePoint 0-Day Explained: Insights from the Eye Security Team

🗓️ Friday, July 25th - 11:00 - 11:30 | Live Q&A included
Language: English

On July 18, Eye Security’s research team was the first to detect a critical zero-day in Microsoft SharePoint (CVE-2025-53770/53771). Hours later, we uncovered mass exploitation affecting thousands of organisations worldwide.

In this 30-minute webinar, our experts reveal how our 24/7 SOC responded, what we learned about the attackers’ tactics, and why this threat remains critical even after patching.

You’ll get:

  • What exactly happened on July 18? How Eye Security became the first to detect the mass SharePoint attacks and what we saw at one of our customers.
  • How did the attackers pull it off? A closer look at the exploit chain and how they stole cryptographic keys to maintain access.
  • Could your SharePoint environment be affected? What to check for and key signs that your servers may already be compromised.
  • Why isn’t patching enough? Insights on how attackers can stay hidden even after updates, and what extra steps you need to take.
  • How to protect your organization now Practical actions to detect, isolate, and recover before attackers gain a foothold.

This session is for IT leaders, security teams, and partners seeking clarity on one of 2025’s biggest cyber events.

It feels great to know that someone is looking over your shoulder 24/7 at a network level. Now I can sleep with two eyes closed.

Hans Raaijmakers, Owner.
I can really talk to them and they think constructively. They don’t just come in with some commercial product.

It is very nice to work with a supplier that not only speaks the language of our business, but also works with our IT supplier.
