The advisory explicitly states the entire package is malware (CWE-506) designed to exfiltrate cryptocurrency wallets, but no specific functions are disclosed in available sources. The npm registry entry now shows a security placeholder rather than original code, and there are no commit diffs/patches to analyze. Without access to the original malicious implementation details or function names from historical versions, we cannot confidently identify specific vulnerable functions. The malware's behavior would likely involve file scanning and network exfiltration functions, but these cannot be mapped to concrete code paths with the provided information.
