On npm install, the package's postinstall hook executes .prepare.cjs, which collects the installer's hostname, username, platform, Node version, non-internal network interfaces, npm registry, and a complete dump of process.env (every key except those prefixed npm_lifecycle), then HTTPS-POSTs the payload as a Lark/Feishu bot message to a hardcoded webhook on open.larksuite.com. The destination hostname is reversed and char-shifted by 7, and the webhook path is XOR-decoded with key Zk9x at runtime to hide the endpoint. Before sending, the script runs sandbox/honeypot evasion: char-code-decoded checks for AWS example credentials and honeypot tokens (PYPI_POISON_HONEY_TOKEN, PP_ARTIFACT_SHA256, THREAT_ANALYZER_MODEL, ASPECT_TLOG), sandbox env prefixes (SANDYCLAW_, OPENCLAW_, PERMISO_, CHAINRADAR_), hostname regex matching detonat|cuckoo|virus|scan|chainradar, and usernames such as sandbox and malware. The package's declared homepage/repository.url is an RFC1918 internal address (http://192.168.100.4:9088/app/lzy-basic-module.git) inconsistent with publishing to the public npm registry, and the stated purpose ("Support WoPet ui") is unrelated to the postinstall beacon. The combination of obfuscated author-controlled destination, full process.env exfiltration, and explicit sandbox evasion is unambiguous credential-theft malware.
