News. Microsoft Warns of ViewState Code Injection Attacks Using Publicly Disclosed Machine Keys. By Chris Paoli 02072025 Microsoft Threat Intelligence has identified a limited attack campaign

Microsoft's security researchers observed limited malicious activity in December 2024, when a threat actor leveraged a publicly disclosed ASP.NET machine key to perform a ViewState code injection attack. During the investigation, Microsoft found that developers had embedded machine keys from publicly accessible sources such as code

Microsoft warns of 3,000 publicly disclosed ASP.NET machine keys that enable ViewState code injection attacks, leading to remote code execution risks quotIn addition, a hash of the view state data is created from the data by using a machine authentication code MAC key. The hash value is added to the encoded view state data and the resulting

However, threat actors also use machine keys from publicly available sources in code injection attacks to create malicious ViewStates used by ASP.NET Web Forms to control state and preserve pages

Code injection is a computer security exploit where a program fails to correctly process external data, Other approaches must be taken, however, when dealing with injections of user code on a user-operated machine, which often results in privilege elevation attacks. Some approaches that are used to detect and isolate managed and unmanaged

Code injection refers to attacks that involve injecting malicious code into an application. The application then interprets or executes the code, affecting the performance and function of the application. Code injection attacks typically exploit existing data vulnerabilities, such as insecure handling of data from untrusted sources.

An unattributed threat actor has been observed exploiting publicly disclosed ASP.NET machine keys to perform ViewState code injection attacks, delivering the Godzilla post-exploitation framework. Over 3,000 publicly disclosed keys have been identified as potentially vulnerable to this attack method.

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

Code Injection is the general term for attack types which consist of injecting code that is then interpretedexecuted by the application. This type of attack exploits poor handling of untrusted data. These types of attacks are usually made possible due to a lack of proper inputoutput data validation, for example
