About the issueโ
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. Certificates have a validity period during which they can be used to create signatures. 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. We detected that the digital signature was not countersigned for time-stamping, and that the signing certificate has expired. Failing to countersign software components may result in application errors and availability outages.
How to resolve the issueโ
- Acquire a new certificate and re-sign the software component.
- Apply the optional time-stamping countersignature during signing.
- With Microsoft SignTool, you can specify the trusted remote time-stamping server using the /t or /tr parameter.
Incidence statisticsโ
ReversingLabs periodically collects and analyzes the contents of popular software package repositories for threat research purposes. Analysis results are used to calculate incidence statistics for issues (policy violations) that Spectra Assure can detect in software packages.
This section is updated when new data becomes available.
Total amount of packages analyzed
- RubyGems: 183K
- Nuget: 644K
- PyPi: 628K
- NPM: 3.72M
Total detections per repository
For every repository, the chart shows the number of packages that triggered the software assurance policy. In other words, it shows how many packages in each package repository were found to have the specific issue described on this page. This information helps you understand how common the issue is across different software communities.
If a repository is absent from the chart, that means none of the packages in that repository triggered this policy during analysis, or the policy was not used during analysis.
Distribution of total detections by project popularity
For every repository, the chart shows how many of the total detections belong to the Top 100 (1-100), Top 1000 (101-1000) and Top 10 000 (1001-10 000) most downloaded projects. This information helps you understand the impact of the issue within each community, making it clearer when the issue affects the most popular projects.
If the chart shows zero values for all of the top project groups, that means all detections were in unranked projects (lower than 10 000 on the list of most downloaded projects).
