when u hack the client side, the server side does not synchronize.
when u use the hacked octopus card (client side) to buy something, those shops (e.g. welcome supermkt, manning, watsons etc) proxy side will execute the order but then later, the server side will send error message and escalate to investigation.
如他不貪心, 只買自己要用的生活物品, 在以下情況買:
(1)跨2區去買. e.g. if u live in CWB, u cross two districts to tin hau to north point
or to wanchai to admiralty/central
(2)買時, 帶粗框眼鏡, 帶cap
(3)著深色沒logo的外套
(4)只買自用不轉售
可惜他貪大了, the clue he was caught was, proxy sides are all from manning/watsons and commodities are mostly ..... milk pwder.
又用了, 自己單一個account 上auction house.
本來他可永遠不被捕.
有心思(to hack octopus by stealing a device), 有技巧, 卻用在錯的地方.
希望有朝一日, 他會去看 movie "catch me if u can", 將聰明用得其所去幫助社會/雞構/公司/需要被幫的人.
