How to configure Hashcat to append some data?

Why do you not just mention the error message ?

I guess it's this:
Quote:Integer overflow detected in keyspace of mask: ?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3

The problem now is not the syntax, but the infeasibility.

Just do the math. It's mathematically infeasible. You are trying to brute-force 16 unknown bytes: 16*16*16*...*16*16*16 = 16^16 = 18,446,744,073,709,551,616

as you can see, that's a very huge number. A tremendous large keyspace. It's impossible to find 16 random bytes within a reasonable amount of time (within dozens of years). You could just play around and make the unknown part shorter or reduce the number of bytes in the custom charset and see how many years it would take for instance if only 0123456789 was allowed and how quickly the time needed increased with increasing number of chars in the charset etc
