Enumerating Users and Mailboxes in Microsoft Outlook 365 Web

During our research into Microsoft 365 security, we discovered a flaw in Outlook on the web (OWA) that exposed information about users and their mailboxes. By manipulating certain request headers against the “/owa/service.svc” endpoint, an attacker could not only confirm whether a user account existed, but also determine if that account had a mailbox associated with it.

It's 2 AM. Do You Know Which AIs Your MCP Server Is Talking To?

When Anthropic dropped the Model Context Protocol (MCP) in late 2024, it felt like the missing puzzle piece for AI tooling: a standard way for Large Language Models (LLMs) to talk to data sources, APIs, and pretty much anything else you can think of. Think of it as a USB-C port for AI, as the protocol’s creators like to say. But like most shiny new standards, the devil’s in the details.

Threat Research Year In Review - 2025

In November of last year, Aaron Bray made some supply chain security predictions for 2025. Now, as we approach the close of the year, we are going to look at how those predictions turned out. But first let’s start with the high-level statistics and review some of the campaigns we have been tracking and reporting on this year. As this year is not yet over, we have excluded data from December for both 2024 and 2025.

Adversarial AI: The New Symmetric Threat Landscape

ionCube Encoding vs Open Source Debate: Why smart developers protect their code but don't lock everything down.

When it comes to distributing PHP applications, discussions often swing between two extremes: fully open-source everything or lock all your code behind encryption/encoding. Critics of encoding often argue that open source is superior because users can still inspect and customise code. But the truth is far more nuanced, and the most successful software vendors already know it.

Why I'm leading Tines' internal workflow transformation

I first met Tines co-founders Eoin Hinchy and Thomas Kinsella more than a decade ago at eBay. Even then, we shared the same frustration: too much important work was slowed down by brittle processes, manual handoffs, and disconnected tools. We all believed technology should help people focus on meaningful work, not slow them down in muckwork. That idea has shaped my career ever since. I started out in security operations, using automation to make my own job easier.
