Detected presence of software components that have low popularity or number of downloads.

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. Software developers publish components they have authored to public repositories. While a new software project is a welcome addition to the open source community, it is not always prudent to indiscriminately use the latest components when building a commercial application. Irrespective of the software quality, the danger of being the first to try out a new project lies in the fact that the software component may contain novel, currently undetected malicious code. Therefore, it is prudent to review software component behaviors and even try out software component in a sandbox, an environment meant for testing untrusted code.Prevalence in PowerShell Gallery community

Next steps
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 presence of software components that are rarely included by other public software packages.

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 PowerShell Gallery 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.
Detected digital signatures that have not been performed with an extended validation certificate.
signatures
Problem
Digital signatures are applied to applications, packages and documents as a cryptographically secured authenticity record. Signatures are made using digital certificates, which can either be purchased from certificate authorities or be self-issued. When a certificate is purchased from a certificate authority, the subject that requests it goes through an identity validation process. Depending on the certificate type, those checks can be basic or extended. Confirming the subject identity is a multi-step process, and the requesting subject can be mapped to its legal entity name only through extended validation of submitted documents. Extended identity validation typically costs more, and it takes longer for a certificate to be issued when this process is correctly followed.Prevalence in PowerShell Gallery community

Next steps
Consider the benefits of acquiring extended validation certificates. Operating systems tend to be more trusting of software packages signed in this way. Certain security warnings and prompts might also be automatically suppressed. This reduces the number of support tickets for organizations that opt to use extended validation certificates.
Problem
Private keys and certificates are considered sensitive information that should not be included in released software packages. However, developers frequently release sensitive information alongside their applications to facilitate automated software testing. Testing keys and certificates often proliferate through the software supply chain. When such information gets shared publicly, it is catalogued by file reputation databases. Any private key and certificate files seen by a file reputation database prior to configured time threshold can be automatically suppressed. Commonly shared sensitive information is not considered to be secret.Prevalence in PowerShell Gallery community

Next steps
Review the commonly shared sensitive information for evidence of inadvertently exposed secrets.
If the keys were published unintentionally and the software has been made public, you should revoke the keys and file a security incident.
