Description
The npm package longzy-basic-ui version 2.0.3 contains malicious code that executes during installation. Its postinstall script collects extensive environment data including hostname, username, platform, Node version, network interfaces, npm registry, and most environment variables, then exfiltrates this information to a concealed webhook on open.larksuite.com. The malware employs obfuscation and sandbox/honeypot evasion techniques to avoid detection. The package metadata is inconsistent with its public registry presence, indicating malicious intent. This behavior constitutes credential-theft malware.
