About the issue
Uniform Resource Locators (URLs) are structured addresses that point to locations and assets on the internet. URLs allow software developers to build complex applications that exchange data with servers that can be hosted in multiple geographical regions. URLs can commonly be found embedded in documentation, configuration files, source code and compiled binaries. One or more embedded URLs were discovered to link to the file attachments hosted on Discord. Attackers often abuse popular web services to host malicious payloads. Since file-sharing services URLs are typically allowed by security solutions, using them for payload delivery increases the odds that the malicious code will reach the user. While the presence of Discord file-sharing locations does not imply malicious intent, no software should be directly linking to a Discord file attachment. An increasing number of software supply chain attacks in the open source space leverages the Discord file-sharing service to deliver malicious payloads.
How to resolve the issue
- Investigate reported detections.
- If the software should not include these network references, investigate your build and release environment for software supply chain compromise.
- You should delay the software release until the investigation is completed, or until the issue is risk accepted.
- Remove all references to flagged network locations.
