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. Open source projects are the intellectual property of their respective authors. At any time, the authors may choose to completely remove the software component from a public repository. This often occurs when a software project reaches its end-of-life stage, or when the software authors lose interest in maintaining the project. This kind of removal frees up the software package name, its unique software identifier in the public repository, for other developers to use. However, new software project owners might have malicious intent. Threat actors are continuously monitoring popular package names in case their unique identifiers suddenly become available for hijacking. Once the software projects falls under new ownership, the new maintainers may opt to use the project popularity to spread malware to unsuspecting users.

Next steps

Inspect behaviors exhibited by the detected software components.
If the software behaviors differ from expected, investigate the build and release environment for software supply chain compromise.
Revise the use of components that raise these alarms. If you can't deprecate those components, make sure that their versions are pinned.
Avoid using this software package until it is vetted as safe.

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. Developers that use open source components within their applications can specify the exact version of the component their application depends on. However, since components are frequently updated, some developers opt to always use the latest version of the software component. This helps reduce the number of vulnerabilities that open source components can introduce in the application. However, it does expose the developer and the build environment to risks associated with software supply chain attacks. Should a threat actor hijack the ownership of the software component publishing account, or even its publishing token, they could issue a malicious update that can infect the build environment or the application itself. To ensure that the build system updates the software component to a malicious version, threat actors often set the version number to an unusually high value. If a build system is instructed to use the latest component version, it will install the component with the highest version number, and execute its code.

Is tslib malicious or is it safe to use?

The npm package tslib has been removed from registry. It was scanned for malware, software tampering, risky behaviors, exposed secrets and known vulnerabilities. Malware or tampering has been detected, making it unsafe to use. The package contains risks, and the analysis results should be reviewed before it is used. Visit the Issues and Behaviors sections of the analysis for more details.

Is tslib popular?

The npm package tslib ranks among the top 10 projects in this community. It has 43B recorded downloads. A package's popularity is not a good indicator of its safety, visit the SAFE Assessment section to see the full analysis of package deployment risk categories.

How do I secure tslib once it is in my app?

Since we can't know when or where malicious attacks will happen, we recommend tracking how tslib behaviors change over multiple software releases. By adopting differential analysis in your release process, you can detect unexpected changes to a tslib version, which can prevent advanced software supply chain attacks. Read how our technology can help prevent future attacks similar to SolarWinds and 3CX.

Did you know...

... that you can use ReversingLabs’ Spectra Assure platform to perform regular risk assessments of packages you develop in-house?

We recommend continuous software safeness monitoring through CI/CD integrations and pre-release/deployment checks. In addition to basic package information found on this page our platform offers rich reports for developers and DevSecOps that help them remediate all reported issues.
