The Microsoft Secure Future Initiative (SFI) stands as the largest cybersecurity engineering project in history and most extensive effort of its kind at Microsoft. Now, we are sharing the second SFI progress report, which highlights progress made in our multi-year journey to improve the security posture of Microsoft, our customers, and the industry at large.
Silk Typhoon is a Chinese state actor focused on espionage campaigns targeting a wide range of industries in the US and throughout the world. In recent months, Silk Typhoon has shifted to performing IT supply chain attacks to gain access to targets. In this blog, we provide an overview of the threat actor along with insight into their recent activity as well as their longstanding tactics, techniques, and procedures (TTPs), including a persistent interest in the exploitation of zero-day vulnerabilities in various public-facing appliances and moving from on-premises to cloud environments.
Discover how Microsoft secures AI models on Azure AI Foundry, ensuring robust security and trustworthy deployments for your AI systems.
The rise in sophisticated cyberthreats demands a fundamental shift in our approach. Organizations must rethink remote assistance security through the lens of Zero Trust, using the three key principles of Verify Explicitly, Use Least Privilege, and Assume Breach as a guide and ensuring that every session, user, and device is verified, compliant, and monitored before access is granted.

Microsoft Threat Intelligence Center discovered an active and successful device code phishing campaign by a threat actor we track as Storm-2372. Our ongoing investigation indicates that this campaign has been active since August 2024 with the actor creating lures that resemble messaging app experiences including WhatsApp, Signal, and Microsoft Teams. Storm-2372’s targets during this time have included government, non-governmental organizations (NGOs), information technology (IT) services and technology, defense, telecommunications, health, higher education, and energy/oil and gas in Europe, North America, Africa, and the Middle East. Microsoft assesses with medium confidence that Storm-2372 aligns with Russian interests, victimology, and tradecraft.

Microsoft is publishing for the first time our research into a subgroup within the Russian state actor Seashell Blizzard and its multiyear initial access operation, tracked by Microsoft Threat Intelligence as the “BadPilot campaign”. This subgroup has conducted globally diverse compromises of Internet-facing infrastructure to enable Seashell Blizzard to persist on high-value targets and support tailored network operations.

Microsoft Threat Intelligence observed limited activity by an unattributed threat actor using a publicly available, static ASP.NET machine key to inject malicious code and deliver the Godzilla post-exploitation framework. In the course of investigating, remediating, and building protections against this activity, we observed an insecure practice whereby developers have incorporated various publicly disclosed ASP.NET machine keys from publicly accessible resources, such as code documentation and repositories, which threat actors have used to launch ViewState code injection attacks and perform malicious actions on target servers.
