🚨 New Website Alert!

Over the past few months, we’ve been rethinking our brand presence. We wanted a new look that captured how we’ve grown, from a lean team of cybersecurity and privacy professionals to a mature global consultancy backed by a team of experts.

Working with our long-term collaborator, Foursets (also a Webflow Premium Partner), we transformed our visual identity—changing up our website and logo—in order to create something that mirrors the work we do every day for business leaders.

🛑 Microsoft Zero-Day Vulnerability (CVE-2026-21509): Emergency Patch Issued for Active Exploitation 

At the end of January, Microsoft issued an out‑of‑band emergency security update to address a newly discovered Microsoft Office zero‑day vulnerability that has been actively exploited in real‑world attacks.

What is CVE-2026-21509? 

Microsoft attributes the flaw to “reliance on untrusted inputs in a security decision,” allowing attackers to bypass OLE mitigations, which is a key safeguard intended to block unsafe COM/OLE objects embedded inside Office files.

Hackers exploit the flaw by:

  • Sending a maliciously crafted Office file 

  • Convincing a user to open the file (Preview Pane does not trigger exploitation)  

  • Leveraging manipulated metadata to trick Office into treating unsafe embedded objects as trusted 

The Impact:

Once opened, the document may execute attacker‑controlled code within a permissive context, enabling potential follow‑on actions such as persistence or additional payload delivery.

How Organizations Should Respond:

Immediate patching, layered hardening, and improved phishing resistance are critical to minimizing exposure. For organizations still operating older Office versions, this zero‑day highlights increasing security trade‑offs associated with maintaining perpetual‑license environments. 

đź’» Legacy System Modernization: A Step-by-Step Guide

Legacy system modernization is the process of updating outdated business technology, which can include legacy apps, infrastructure, databases, and processes, to create scalable and secure technology systems that fulfill modern digital needs. The modernization of legacy applications is often a key consideration of digital transformation initiatives.  

Outdated legacy systems can create what is called process debt, which is the accumulation of redundancies and inefficiencies in workflows over time. Digital transformation projects target these inefficiencies, which can cost businesses both money and time and lead to devastating incidents, like security breaches.
