The cat-and-mouse battle between game makers and cheat makers has seen plenty of inventive twists and turns over the years. Even amid that backdrop, though, Dota 2 stands out for a recently revealed "honeypot" trap hidden inside the game's memory buffer.

In a blog post this week, Valve revealed the existence of this trap, which was released as part of an earlier update to the game. Valve says that update included "a section of data inside the game client that would never be read during normal gameplay." But that memory could be read by third-party cheat tools that used exploits to sniff out (and share) internal data that is normally invisible to players.
