@jenish094/providers@3.3.2
Package that contains all the providers of j-stream
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package is not proven malicious, but its automatic unpinned npx preinstall creates a genuine unresolved install-time supply-chain risk. The obscured runtime endpoint appears tied to its streaming-provider functionality rather than a confirmed attack.
Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
npm installation triggers preinstall; application use triggers provider scraping.
Impact
The install hook adds an avoidable external supply-chain execution path; no concrete data theft or system mutation was found.
Mechanism
Automatic unpinned npx execution and runtime streaming API requests.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The preinstall hook automatically runs an unpinned package through npx during installation.
- A provider decodes an obscured external API URL and sends requests to it at runtime.
Evidence against
- The inspected bundle contains no filesystem harvesting, shell execution, environment access, or persistence code.
- The runtime network code is structured as streaming-provider scrapers and uses caller-supplied fetcher controls.
- There is no self-dependency or package code that mutates the consumer project.
