Analysis

selfsigned-certificate@1.0.0 is a backdoored SSL-certificate generator. When generateCertificates(10) is called (a magic count value), the module POSTs to hxxps://jetpack[.]cv/wp-json/selfsigned-certs/v3/init with a hardcoded Basic-auth credential ([account]), base64-decodes the response, and executes it via eval() — arbitrary remote code execution from the attacker-controlled endpoint. The remote payload is served at runtime, not shipped in the tarball. C2 endpoint: hxxps://jetpack[.]cv/wp-json/selfsigned-certs/v3/init.
