Malicious code in etoro-aggregator (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 (d7d5f0fb8c06c23afad28686a3d3d689dfc5a3786c73bff2c569fd8b55f2b4ad) The package's preinstall.js lifecycle script executes automatically on `npm install` and performs reconnaissance on the installer host. It collects hostname, username, current working directory, platform, and the output of OS commands including `whoami /all`, `ipconfig /all` / `ifconfig`, `tasklist` / `ps aux`, directory listings of `/`, `C:\`, and the user's home, and a dump of environment variables. The collected data is transmitted via HTTP GET and POST to the hardcoded bare IP endpoint `http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/v4/...`. The package's declared main is an empty stub and its description ("Internal service client library") combined with the implausibly high version number `99.0.2` is consistent with a dependency-confusion attack targeting an internal `etoro-aggregator` name. The manifest plus the preinstall script constitute the entire payload; installing the package leaks installer host identity, network configuration, filesystem structure, and environment variables (which routinely contain credentials and tokens) to an attacker-controlled endpoint.
