  • testt22esttestNuGet package containing malicious code

The testt22esttest NuGet package was found to contain malicious code. This incident was identified and documented by the OpenSSF's malicious packages initiative, which tracks and catalogs known malicious software packages across multiple ecosystems.\n\nThe package was published to the NuGet package repository and could have been downloaded by developers who depended on it. The malicious nature of the package was confirmed and reported through GitHub's advisory system (GHSA-7jjw-38rf-79jg).\n\nThis appears to be a case of a deliberately malicious package being published to a public package repository, likely as a test case or proof-of-concept by the OpenSSF project to demonstrate supply chain risks.
