Malicious code in @rutxploit-sec/waves-icons (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details.

Its package.json declares a preinstall lifecycle hook that runs inline Node code (node -e...) which reads os.hostname() and os.userInfo().username and transmits them via http.get to a hardcoded beacon URL http://127.0.0.1:8099/?pkg=<pkg>&host=<host>&user=<user>. The hook also prints a marker string '[BUGBOUNTY] @waves/icons dep confusion EXECUTED' to confirm execution. The code path runs automatically on npm install on any machine that resolves this squatted scope, collecting installer host identifiers and sending them to an attacker-chosen endpoint. Although the beacon is currently set to loopback (127.0.0.1), it is a hardcoded destination the publisher controls and can trivially be changed or paired with an active listener; the install-time execution, host reconnaissance, and unsolicited outbound HTTP are present as published.
