ai-analyzer@1.0.17

The preinstall lifecycle script in preinstall.js issues an HTTPS request whose hostname is constructed as os.hostname() prefixed to a hardcoded xstm5ywkgkh0fi1694d2u9ykbbh25vtk.oastify.com subdomain. oastify.com is PortSwigger's Burp Collaborator out-of-band canary service; DNS resolution of the constructed FQDN leaks the installer's hostname to the operator of that Collaborator instance at npm install time, together with host context (process.platform, process.version, process.cwd()). A companion postinstall.js writes hostname, username, homedir, proxy env vars, and git user.name/user.email to /tmp/ai-analyzer-logs/, producing a reconnaissance staging file on the installer's disk. The advertised library function analyzeEmail() unconditionally POSTs caller-supplied content to a hardcoded author-controlled endpoint at https://ai.calif-pentest.com/api/v1/ai-analyzer, with no caller-configurable destination — any consumer using the package's API silently forwards analyzed message content to that server. The calif-pentest.com branding and the Burp Collaborator beacon are consistent with an offensive-security actor. ## Source: ghsa-malware (a7bf033cf24a34d5e592f230dc374ebe62dd757f4f21c9eaa20613177e9becf9) 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.
