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 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. The post Code injection attacks using publicly disclosed ASP.NET machine keys appeared first on Microsoft Security Blog.
