Techno-geeks having fun
Some time ago, on the forums of amateurs to play sports betting (specifically on football), there was a rumor about people who thoroughly know the results of the “contract” matches in European divisions.
“Thorough knowledge” was confirmed by the expulsion of an archived archived Excel file with the results before the start of the series of games. Two passwords - to the archive and Excel - were sent after the end of the series of games. After that, the results of the matches really showed in Excel. Riddle?
The authors demanded quite substantial money for their knowledge.
How it was: The password was entered twice: on unzipping and when opening the Excel file. When opening Excel, the password was requested by the VBA script. The password itself was a 9-digit sequence in which the results of the matches were encrypted. Then the VBA script decrypted the password and scattered the data in the cells.
Elegantly, huh?
