Problem
Software developers use programming and design knowledge to build reusable software components. Software components are the basic building blocks for modern applications. Software consumed by an enterprise consists of hundreds, and sometimes even thousands of open source components. Open source communities depend on the work of thousands of software developers that volunteer their time to maintain software components. Software developers build up the reputation of their open source projects by developing in public. Modern source code repositories have many social features that allow software developers to handle bug reports, have discussions with their users, and convey reaching significant project milestones. It is uncommon to find open source projects that omit linking their component to a publicly accessible source code repository.Prevalence in NuGet community

Check the software component behaviors for anomalies.
Consider exploratory software component testing within a sandbox environment.
Consider replacing the software component with a more widely used alternative.
Avoid using this software package until it is vetted as safe.
Detected digital signatures that have been countersigned for time-stamping an excessive number of times.
signatures
Problem
Digital signatures are applied to applications, packages and documents as a cryptographically secured authenticity record. Signatures verify the origin and the integrity of the object they apply to. For application signatures, or digital code signing, it is recommended to countersign the signatures for time-stamping. Countersigned software components have their signature period validity extended past the signing certificate expiration date. Such signatures are considered valid indefinitely. However, time-stamping only needs to be done once per signature. Applying an excessive number of countersignatures may cause validation issues and availability outages.Prevalence in NuGet community

Consult the certificate authority code signing documentation.
With Microsoft SignTool, you can specify the trusted remote time-stamping server using the /t or /tr parameter.
Detected digital signatures that rely on a weak digest algorithm for integrity validation.
signatures
Problem
Digital signatures are applied to applications, packages and documents as a cryptographically secured authenticity record. Signatures verify the origin and the integrity of the object they apply to. The integrity validation relies on the cryptographic strength of the encryption and the hash verification algorithm. If either of the two is considered weak by current standards, there is a chance the signed object could be maliciously modified, without triggering the integrity failure check.Prevalence in NuGet community

Next steps
Create signatures with strong ECC key-length of at least 224 bits, or RSA key-length of at least 2048 bits, and use SHA256 as the hashing algorithm. While encryption key-length upgrade does require you to obtain a new certificate, the hashing algorithm can freely be selected during signing.
With Microsoft SignTool, you can specify the hashing algorithm using the /fd SHA256 parameter.
