Malicious code in simplisafe-gatsby (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 (564baff2e47527f159c52c527e1ea2b93d73625f94737f4397cff99311871a18) On `npm install`, the package's preinstall hook (`package.json` declares `"preinstall": "node index.js"`) executes index.js, which collects the installer's hostname, username, home directory, DNS configuration, package metadata, and the contents of /etc/passwd and /etc/hosts (via fs.readFileSync), then POSTs the collected data over HTTPS to a Burp Collaborator subdomain at xpqamgvad3ok4bc11xar5t7q8he820qp.oastify.com. The package has no advertised functionality (empty author, empty description, single recon payload file) and its name is consistent with a dependency-confusion attempt against SimpliSafe's internal Gatsby package namespace. Any machine that runs `npm install` against this name will leak system identity and local-account information to the attacker. ## Source: ghsa-malware (28fdfe170233a2cc83320ece5c3ee4b6480017f27a0d1b2fb00e1048903a023b) 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.
