Malicious code in @siriusbeyond/ui (npm)

CISA 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.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

The lifecycle commands are wrapped in `2>/dev/null || true` to suppress errors and hide the exfil from the installer during `npm install`. A README framing this as a dependency-confusion proof of concept does not change the behavior: the package auto-executes credential-context reconnaissance and host fingerprinting against installer machines and transmits the results to an attacker-controlled Telegram channel.
