The code appears to be a legitimate BUAA classroom extraction utility, not malware. However, it handles highly sensitive browser credentials: it decrypts local cookies, derives a bearer token, and stores plaintext cookies and authorization data in a reusable cache. The cache and temporary cookie copy should be protected with restrictive permissions, minimized, and preferably replaced with an OS-secure credential store or short-lived session handling. Use is unsafe on shared or compromised systems until this credential-storage issue is addressed.
