Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

                "put %s\n"
                "ls \n"
                "EOF\n",
                ftp_ip,
                ftp_port ? ftp_port : 21,
                ftp_uname ? ftp_uname : "an****ous",
                ftp_pwd ? ftp_pwd : "an****ous",
                src_dir, out_file);
        fclose(f);

        if (chmod("ftp.sh", S_IRUSR | S_IWUSR | S_IXUSR) < 0) {
                sigma_dut_print(dut, DUT_MSG_ERROR, "Failed to chmod ftp.sh");
                unlink("ftp.sh");

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
