Malicious code in keroeltopkkk (npm)
Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (2758c1a2619db534fdc8e2981e051769b20641492d12ff984e333446e0c734e3) The package ships a single server.js that is wired into every npm lifecycle hook (preinstall, install, postinstall, prepare, prepublish, preprepare, postprepare). On npm install the script reads os.hostname() and issues an HTTPS GET to the hardcoded endpoint https://eo8f3m3ho26a0nm.m.pipedream.net/, sending the installer's hostname and the package name as query parameters to an author-controlled pipedream.net webhook collector. The package has no other functionality: package.json carries an empty description, a placeholder ISC license, a name resembling a token, and version 99.99.99 — the canonical shape used to probe whether a private/internal package name resolves against the public npm registry (dependency confusion). The exfiltrated hostname discloses internal build-host or developer-machine identifiers to the beacon operator.
