Malicious code in @coopeuch/components (npm)
GitHub lists this malware advisory for @coopeuch/components. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.

## Source: amazon-inspector (042f083be94ae23751c73b5a73c0f11e4e9ecafd9ee9f1caa8c05b367ac71de8) The package declares a `postinstall` script (postinstall.js) that runs automatically on `npm install` and collects a broad set of installer-side identifiers: hostname, username, uid/gid, home directory, platform, non-internal network interfaces with MAC addresses and CIDRs, configured DNS servers, internal reverse-DNS name, container runtime indicators, `npm_*` environment variables including the configured registry and scoped registry settings, CI marker variables, and the consuming project's package.json name, version, and declared dependency range for this package. The collected payload is POSTed as JSON to `https://collector.oob.s4yhii.com/_npm-poc/beacon`, and a DNS lookup beacon is issued against a subdomain of `*.oob.s4yhii.com` that encodes the package name as a label. The package is published under the `@coopeuch` scope at an implausibly high version `1.999.999` and specifically introspects the consumer manifest's declared dependency range and the installer's configured registry — a shape consistent with a dependency-confusion squat against an internal scope.

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
