Default Re: Mumbling about MP security

The methods of cheating discussed in this forum (with the exception of Taqwus) seem to focus on alteration of *data* files of the game in question, in two forms:

1. The machine on which the game was hosted was compromised and the fatherland file was edited to change game state. Than the modified, but structurally valid fatherland file was used the hosting Dominions 2 system generate the next turn

2. Either trn or 2h files were modified such that an illegal (but structurally valid) 2h file was returned to the server, which failed to detect the inconsistency in the game state.

Both of these methods assume that the hosting installation of Dominions was operating correctly on the input it was given (although it may be insufficiently paranoid).

If 1) is the true scenario than this clearly need not be the case, the attack would have had access to the executable, configuration information, and runtime state during hosting.

Even if the attacker does not have root access on the hosting server, there is the possibility of a remote exploit in Dominions, either through structurally invalid 2H files or attacks through the network connection.
In short, it may be that the server was coerced to generate invalid turn files, rather than failing to detect subtle modification of an otherwise valid input.

I won’t speculate further as to how this could be carried out.

Of course, the devs may have reason to rule these sorts of attacks out.
