Mailbox Auditing: The Missing Defense Against BEC
Threat actor Storm-2502 is a reminder that modern BEC doesn’t need malware. It needs access, context, and time inside your mailbox. This threat actor runs a professional money-laundering operation supporting BEC fraud. Once an email account is compromised, they study invoice threads, vendor relationships, and payment workflows. From there, it’s impersonation, payment redirection, and stolen […]
Why MFA No Longer Stops Modern Phishing Attacks
For years, organizations were told that enabling MFA would dramatically reduce phishing risk. And for a long time, that was true. That era is over,, however! Microsoft Threat Intelligence recently detailed the evolution of Tycoon2FA, one of the most widespread phishing-as-a-service platforms operating today. Its success exposes a hard truth for mid-market organizations: attackers are […]
RedVDS Cybercrime Infrastructure Fueling Cyber Fraud
Most organizations still focus solely on “tactics, techniques, & procedures (TTPs)” used by threat actors. That’s a mistake. Today’s biggest financial losses don’t start with custom malware or zero-days. They start with industrialized cybercrime infrastructure, which is scalable and purpose-built to make cyber fraud fast, cheap, and hard to trace. Microsoft tracks one of the […]
Securing the Supply Chain Requires More Than Data
Supply chain security doesn’t fail because organizations lack data. It fails because accountability is unclear, trust is assumed, and security is fragmented. Organizations have more data than ever. More vendor assessments. More dashboards. More alerts, yet breaches tied to third parties and shared platforms continue to escalate. We believe supply chain cyber resilience must be […]

Cybersecurity Hiring Is Slowing, But AI Alone Won’t Help Your SOC
Budgets are flat. Headcount growth is shrinking. Yet breaches, phishing, and ransomware are accelerating. All now supercharged by AI. This isn’t a talent crisis. It’s a labor market reset in cybersecurity. Organizations aren’t cutting people indiscriminately. They’re cutting manual, low-value work and reallocating spend toward automation that actually reduces risk. The mandate from boards and […]
Shadow AI Is Already in Your Microsoft Tenant—Do You Know Where?
How mid‑market orgs can find and contain Shadow AI with a free Microsoft-native AI Risk Assessment Shadow AI is not an emerging risk; it is already embedded in how your teams use Microsoft 365, Copilot, Azure OpenAI, and third-party AI tools connected to Entra ID. CyberMSI’s free AI Risk Assessment gives you a verified inventory […]
Prompt Injection: When Your AI Takes Orders from Attackers
Prompt injection represents one of the most insidious threats facing organizations deploying AI in Microsoft 365. Unlike legacy cyberattacks that exploit software vulnerabilities or steal credentials, prompt injection manipulates AI systems into performing unintended actions by corrupting the instructions they receive. For organizations with Microsoft Copilot or custom AI agents built with OpenAI, Gemini, Claude, […]
AI Deepfake Threats in Microsoft 365: What Security Leaders Need to Know
AI-generated deepfakes represent a growing threat to organizations using Microsoft 365. These sophisticated attacks leverage artificial intelligence to create convincing fake audio and video content, enabling fraud schemes that bypass traditional security controls. For mid-market organizations, understanding and mitigating these risks has become a critical security priority. Cyber insurance providers now explicitly cover reputational harm […]
