275 Million Users Exposed. 8,809 Schools Down. Instructure Calls It "Scheduled Maintenance."
On May 7, 2026, Instructure replaced an active ShinyHunters ransom message on Canvas with a fake “scheduled maintenance” page during finals week at 8,809 schools. This is the third Instructure breach in eight months — a pattern of failed customer service, failed honesty, and failed integrity that, when academic institutions depend on you, crosses into criminal dereliction of duty.

Your Employees Are Running Shadow AI Agents With Admin Access to Everything. You Don't Know About Any of Them.
AI agents — autonomous programs that access email, Slack, Salesforce, SharePoint, and financial systems on behalf of users — are proliferating across enterprise environments without security review, inventory, or governance. Gartner named shadow AI agents the top emerging risk for CISOs in 2026. Google's security team warned they will create invisible, uncontrolled pipelines for sensitive data. Neither adequately described how bad this already is.

Every MFA Tool in Your Stack Is Being Bypassed Right Now. Here's Exactly How.
MFA deployment announcements still appear in board-level cybersecurity updates as evidence that an organization is protected. They are not. The five techniques now routinely used to defeat MFA have been operational for years — and most organizations that deployed MFA in 2020 still have no defenses against any of them.
We Tested Microsoft Defender, CrowdStrike Falcon, and SentinelOne Against the Same Attack. Here's What Actually Stopped It.

Microsoft 365 Copilot Does Not Create a Data Problem. It Reveals the One You Already Have.
Microsoft 365 Copilot is not just another productivity tool. It sits inside the operating layer of modern work: Outlook, Teams, SharePoint, OneDrive, Word, Excel, PowerPoint, and Microsoft Graph. That is why the risk is not theoretical. If your organization is using Microsoft 365, then Copilot is not entering a clean environment. It is entering years of permissions, legacy SharePoint sites, Teams channels, OneDrive links, stale groups, external sharing decisions, sensitive files, abandoned content, and access policies that may or may not still reflect business reality. The uncomfortable truth is simple: Copilot does not create your data governance problem. It reveals the one you already have.

Seven Years. Five Major Outages. Wells Fargo Still Calls It "Routine Maintenance."
A multi-year audit of Wells Fargo's outage history reveals a repeating pattern: power-related infrastructure failures, opaque communication, and prolonged customer impact framed as "routine maintenance." For boards and PE sponsors, the lesson is not that Wells Fargo has IT problems. It is that operational resilience is a structural cyber risk that shows up in patterns, not single events — and that vendor communication language is its own audit-grade signal of governance health.
