CISA is aware of malicious cyber activity targeting endpoint management systems of U.S. organizations based on the March 11, 2026 cyberattack against U.S.-based medical technology firm Stryker Corporation, which affected their Microsoft environment.1 To defend against similar malicious cyber activity, CISA urges organizations to harden endpoint management system configurations using the recommendations and resources provided in this alert. CISA is conducting enhanced coordination with federal partners, including the Federal Bureau of Investigation (FBI), to identify additional threats and determine mitigation actions. To defend against similar malicious activity that misuses legitimate endpoint management software, CISA urges organizations to implement Microsoft’s newly released best practices for securing Microsoft Intune; the principles of these recommendations can be applied to Intune and more broadly to other endpoint management software: Use principles of least privilege when designing administrative roles. Leverage Microsoft Intune’s role-based access control (RBAC) to assign the minimum permissions necessary to each role for completing day-to-day operations—permissions include what actions the role can take, and what users and devices it can apply that action to. Enforce phishing-resistant multi-factor authentication (MFA) and privileged access hygiene. Use Microsoft Entra ID capabilities (including Conditional Access, MFA, risk signals, and privileged access controls) to block unauthorized access to privileged actions in Microsoft Intune. Configure access policies to require Multi Admin Approval in Microsoft Intune. Set up policies that require a second administrative account’s approval to allow changes to sensitive or high-impact actions (such as device wiping), applications, scripts, RBAC, configurations, etc. Additionally, CISA recommends reviewing the following resources to strengthen defenses against similar malicious cyber activity: Microsoft resources: For recommendations on securing Microsoft Intune, see Best practices for securing Microsoft Intune. For guidance on implementing Multi Admin Approval in Microsoft Intune, see Use Access policies to implement Multi Admin Approval. For recommendations on configuring Microsoft Intune using zero trust principles, see Configure Microsoft Intune for increased security. For guidance on implementing Microsoft Intune RBAC policies, see Role-based access control (RBAC) with Microsoft Intune. For guidance on deploying Privileged Identity Management (PIM) across Microsoft Intune, Entra ID, and other Microsoft software, see Plan a Privileged Identity Management deployment. CISA resources: For guidance on implementing phishing-resistant multifactor authentication (MFA), see Implementing Phishing-Resistant MFA.

Midmarket security leaders aren't as secure as they think, says Intruder's report Partner Content The midmarket matters. JP Morgan estimates approximately 300,000 organizations generating $13T in annual revenue. Yet they occupy an awkward position in the security landscape. They're large enough to be attractive targets with complex digital estates, significant revenue, and valuable data, but not large enough to have the headcount, budget maturity, or tooling sophistication of an enterprise security team.…

AI-based assistants or "agents" -- autonomous programs that have access to the user's computer, files, online services and can automate virtually any task -- are growing in popularity with developers and IT workers. But as so many eyebrow-raising headlines over the past few weeks have shown, these powerful and assertive new tools are rapidly shifting the security priorities for organizations, while blurring the lines between data and code, trusted co-worker and insider threat, ninja hacker and novice code jockey.
Malicious insiders are using misusing AI for nefarious gain, while employees cutting corners also creates risk, warns Mimecast
Cloudflare Threat Report warns that AI tools enable attackers who lacked required skills to generate effective attacks rapidly and at scale
In early January 2026, KrebsOnSecurity revealed how a security researcher disclosed a vulnerability that was used to assemble Kimwolf, the world's largest and most disruptive botnet. Since then, the person in control of Kimwolf -- who goes by the handle "Dort" -- has coordinated a barrage of distributed denial-of-service (DDoS), doxing and email flooding attacks against the researcher and this author, and more recently caused a SWAT team to be sent to the researcher's home. This post examines what is knowable about Dort based on public information.
A new report claims that the cost of insider security incidents has surged 20% in two years, reaching an average of US $19.5 million per organization annually, with no sign that the alarming figure is flattening. Read more in my article on the Fortra blog.
