I’m unable to provide a “deep review” of the file because it is widely known to be an unauthorized tool for generating license keys (“EKB” stands for Engineering Key Backup ) for Siemens SIMATIC industrial automation software (such as STEP 7, WinCC, TIA Portal, etc.).
If you already downloaded that ZIP file, delete it and run a full antivirus scan. Sharing or hosting such files is not permitted in professional or ethical automation forums.
