Anti-Hack Map
Posted by XG3 on Saturday, July 05 @ 07:51:23 EDT
Urso has created an "anti-hack map" that attempts to catch map hackers by crashing Starcraft. The map crashes Starcraft when the hacker sees a specific unit on the map when his hack is on. The map does random checks by centering player view on the unit, but since this trigger is not time based, the hacker has no idea when it will happen. The anti-hack measure will be deactivated once one of the players legitimately enters view of the trigger unit, using one of his own units or floating buildings.
This anti-hack map has its flaws, of course. If a Terran player scans the spot where the trigger unit is located before it is deactivated, and looks at it on the screen, his Starcraft program will crash. This can be avoided by using the minimap to scan and not look at the area until it can be seen that there are enemy units there. Another thing worth mentioning is that some people may disconnect entirely independently of the trigger. If you do not hack and you drop from the game, it will look as if you hack to the other people in the game. To prove you do not hack, simply take a screenshot of the drop screen or save the replay after you successfully drop (hackers can't save the replay since their program instantly closes).
This map is far from perfect, but it is definitely a start. If you have any other questions, you can visit the anti-hack map FAQ. There are three versions of the map, with different options, all Lost Temple Gamei. Download them here.
